Wöhlk KE Keratoconus RGP Contact Lenses Malaysia
Advanced Rigid Gas Permeable Lenses for Keratoconus and Irregular Corneas
For most people, blurry vision can be corrected relatively straightforwardly with spectacles or conventional contact lenses.
But keratoconus is different.
Keratoconus changes the shape of the cornea itself. Instead of maintaining a relatively regular curved surface, the cornea becomes thinner and increasingly irregular, often developing a cone-like shape.
As the cornea becomes more irregular, ordinary spectacles may no longer provide the quality of vision a patient needs.
You may experience:
- Blurred vision despite updated glasses
- Increasing or irregular astigmatism
- Ghost images or double outlines
- Glare and halos
- Distorted letters
- Reduced contrast
- Difficulty driving at night
- Frequent changes in prescription
For suitable patients, rigid gas permeable (RGP) contact lenses can provide a very different approach to vision correction.
One specialised option developed specifically for keratoconus is the Wöhlk KE Keratoconus RGP Contact Lens.
Wöhlk KE is not currently available at Malaya Optical, but we are looking to introduce it to our specialty contact-lens portfolio in the future according to patient demand.
What Is Keratoconus?
Keratoconus is a condition affecting the cornea, the transparent front surface of the eye.
A healthy cornea normally has a relatively smooth and regular curvature.
With keratoconus, the cornea becomes thinner and changes shape. The resulting irregularity can produce irregular astigmatism and complex optical distortions.
This is different from ordinary short-sightedness or regular astigmatism.
In early cases, spectacles may still provide satisfactory vision.
As the cornea becomes increasingly irregular, however, patients may notice that even a carefully measured spectacle prescription no longer produces truly sharp vision.
This is one reason specialty contact lenses can become important in keratoconus management.

Why Can Keratoconus Make Vision Blurry Even With Glasses?
Spectacles are excellent at correcting conventional refractive errors such as:
- Myopia
- Hyperopia
- Regular astigmatism
Keratoconus can produce irregular astigmatism and higher-order optical aberrations that are much more difficult for ordinary spectacle lenses to compensate for.
A patient might therefore say:
“I’ve just changed my glasses, but everything still has shadows.”
or:
“The letters are clearer, but they still don’t look sharp.”
This doesn’t necessarily mean the spectacle prescription is wrong.
The irregular corneal surface itself may be affecting the quality of the image entering the eye.
This is where an RGP lens can work differently.
What Is Wöhlk KE?
Wöhlk KE is a rigid gas permeable contact-lens design developed specifically for keratoconus.
Rather than being an ordinary disposable contact lens, it is a specialty lens that requires individual assessment and professional fitting.
The lens is designed to allow practitioners to work with the unusual corneal geometry found in keratoconus.
This is important because no two keratoconic corneas are exactly alike.
The position of the cone, degree of corneal steepening, irregularity, prescription and severity can differ substantially between patients.
The objective isn’t simply:
“Choose the correct power.”
The optometrist also needs to determine:
“How should this lens fit this particular cornea?”
What Does RGP Mean?
RGP stands for Rigid Gas Permeable.
Patients sometimes call RGP lenses “hard contact lenses” because the lens maintains its shape rather than draping over the eye like a conventional soft contact lens.
However, modern RGP materials are designed to permit oxygen transmission.
The rigidity of the lens is actually one of its biggest optical advantages for an irregular cornea.
A soft contact lens largely follows the shape of the cornea underneath it.
An RGP lens maintains a regular front optical surface.
For keratoconus, that difference can be extremely important.
How Can Wöhlk KE Improve Vision With Keratoconus?
This is the concept we want every keratoconus patient to understand.
An RGP lens doesn’t simply place another prescription in front of the eye.
It can help create a more regular optical system over an irregular corneal surface.
When an appropriately fitted Wöhlk KE RGP lens sits on the eye, tears occupy the space between the back of the rigid lens and the irregular corneal surface.
This creates what is commonly referred to as a tear lens.
Together:
Wöhlk KE rigid optical surface + tear layer + irregular cornea
can help mask a significant portion of the optical irregularity caused by the anterior corneal surface.
For suitable keratoconus patients, this can result in vision that is significantly better than what can be achieved with spectacles alone.
This is one of the fundamental reasons RGP contact lenses remain an important form of visual rehabilitation for keratoconus.
Wöhlk KE Is More Than a Prescription
With ordinary spectacles, the prescription is one of the main pieces of information required to manufacture the lenses.
Keratoconus RGP fitting is considerably more complex.
The optometrist needs to understand factors such as:
- Corneal shape
- Corneal curvature
- Location of corneal steepening
- Degree of irregularity
- Lens position
- Lens movement
- Relationship between the lens and cornea
- Vision achieved through the lens
- Comfort
- Overall eye health
This is why Wöhlk KE should be professionally fitted rather than purchased like an ordinary contact lens.
What Makes Wöhlk KE Different From a Conventional RGP Lens?
Not all RGP lenses are designed in the same way.
A conventional RGP lens may work very well for many patients, including some people with keratoconus. However, keratoconus creates a much more complex fitting problem because the size, position, steepness and shape of the cone can vary considerably from one patient to another.
This is where a specialised keratoconus design such as Wöhlk KE can offer an important advantage.
Wöhlk KE provides the optometrist with a greater range of fitting parameters and design options specifically intended for irregular keratoconic corneas.
Instead of treating the cornea as though it has one standard shape, the lens can be selected and adjusted according to factors such as:
- Corneal curvature
- Overall lens diameter
- Base curve
- Peripheral geometry
- Eccentricity
- Corneal sagittal profile
- Size and position of the keratoconus cone
- Degree of corneal ectasia
- Toric or asymmetric fitting requirements
This additional customisation allows the optometrist to work towards a more appropriate relationship between the lens and the individual cornea.
Matching the Lens to the Size of the Keratoconus Cone
Keratoconus does not always produce the same type of cone.
Some patients have a relatively small, central cone, while others have a broader or more displaced area of corneal steepening.
Research into keratoconus RGP fitting has shown that matching the optical-zone and lens diameter to the size and location of the cone can improve fitting success. Smaller centred cones may require a different geometry from larger or more oval cones.
Wöhlk KE is specifically designed to give the practitioner flexibility when fitting these different corneal shapes.
Wöhlk’s own fitting guidance recommends changing parameters such as lens diameter, base curve and eccentricity according to the degree of corneal ectasia, with the aim of achieving an appropriate three-point fitting relationship while maintaining good tear exchange.
This is very different from simply choosing an RGP based on spectacle prescription.
Sagittal Height: Looking Beyond a Simple Corneal Curve
Another useful way to understand specialty lens fitting is through sagittal height.
Sagittal height describes how much the corneal surface rises or falls over a given diameter.
Two corneas can have similar central curvature measurements but very different overall shapes and sagittal profiles.
This becomes particularly important in keratoconus because the cornea is no longer symmetrical or regularly curved.
Research has demonstrated measurable differences in corneal sagittal height between keratoconic and healthy eyes, reinforcing why the overall three-dimensional shape of the cornea matters when selecting a rigid lens.
By considering the corneal topography, cone size and overall sagittal profile, an optometrist can choose a Wöhlk KE geometry that better corresponds to the patient’s individual cornea.
The objective is not simply to make the lens steeper or flatter.
It is to create a more balanced lens-to-cornea relationship.
Why Better Customisation Can Improve Lens Centration
Centration describes how well the contact lens remains positioned over the cornea and visual axis.
With keratoconus, achieving good centration can be challenging.
An irregular or displaced cone may cause a conventional RGP lens to:
- Ride too high or too low
- Move excessively
- Decentre away from the visual axis
- Tilt or rock on the cornea
- Produce inconsistent vision
- Create uneven pressure on the corneal surface
This is one of the areas where the additional customisation available with Wöhlk KE can be valuable.
By adjusting parameters such as:
diameter + base curve + eccentricity + peripheral geometry + toric design
the optometrist can work towards a lens that follows the individual corneal geometry more appropriately.
Wöhlk’s fitting recommendations specifically note that toric back-surface options can help reduce tipping or loss of lens position, while appropriate diameter and peripheral flattening can improve the distribution of the lens over an irregular cornea.
Better centration can potentially contribute to:
- More stable vision
- Better alignment of the optical zone with the pupil
- More predictable lens movement
- More even fitting characteristics
- Reduced lens displacement
- More consistent visual quality
However, the final result still depends on the individual cornea and must be confirmed through diagnostic fitting.
Wöhlk KE vs a Standard RGP for Keratoconus
| Feature | Conventional RGP | Wöhlk KE Keratoconus RGP |
|---|---|---|
| Rigid optical surface | Yes | Yes |
| Can mask irregular corneal optics | Yes | Yes |
| Specifically designed around keratoconus geometry | Depends on design | Yes |
| Multiple eccentricity options | Depends on lens | Yes |
| Wide diameter customisation | Depends on lens | Yes |
| Designed for different degrees of corneal ectasia | Limited in standard designs | Yes |
| Can be adjusted according to cone size and position | Depends on design | Greater fitting flexibility |
| Toric fitting options | Depends on design | Available |
| Ability to optimise centration | Depends on individual fit | Greater customisation may help |
| Requires diagnostic fitting | Yes | Yes |
This doesn’t mean that Wöhlk KE will automatically outperform every conventional RGP in every patient.
A well-fitted standard RGP may still provide excellent vision for some keratoconus patients.
The advantage of Wöhlk KE is greater fitting flexibility when the corneal geometry becomes more irregular or difficult to manage.
Why We Use Corneal Topography Before Choosing the Lens
This additional Wöhlk KE customisation becomes even more useful when combined with corneal topography.
At Malaya Optical, we use the OCULUS Keratograph to map the curvature and shape of the cornea.
The map helps our optometrists understand:
- Where the cone is located
- How large the area of steepening is
- How steep the cornea has become
- Whether the cone is central or displaced
- How asymmetric the cornea is
- How the peripheral cornea changes away from the cone
That information can help guide the selection of diagnostic Wöhlk KE parameters.
The lens is then placed directly on the eye and evaluated using fluorescein assessment.
In other words, we don’t simply choose a Wöhlk KE from a prescription.
We combine:
Corneal topography → cone assessment → lens geometry selection → diagnostic fitting → fluorescein evaluation → vision assessment → parameter refinement
This allows the fitting to be progressively customised to the individual cornea.
The Goal: A More Stable Optical System
Ultimately, all of this customisation has one objective:
to create the most appropriate relationship possible between the rigid lens, tear layer and irregular cornea.
When the lens centres well and remains stable, the regular optical surface of the RGP can remain better aligned with the patient’s visual axis.
For a person with keratoconus, that can translate into:
- Clearer functional vision
- More stable vision throughout the day
- Less fluctuation when blinking
- Better optical-zone positioning
- More predictable lens movement
- Improved overall lens performance
This is why Wöhlk KE is more than simply another RGP lens.
It is a specialised keratoconus fitting system that gives the optometrist greater control over how the lens interacts with an irregular cornea.
Mapping the Cornea With the OCULUS Keratograph
One of the most useful technologies when evaluating an irregular cornea is corneal topography.
At Malaya Optical, we use the OCULUS Keratograph.
Corneal topography creates a detailed map of the curvature and shape of the front surface of the cornea.
Instead of simply knowing:
“This patient has astigmatism.”
we can investigate:
“What does this patient’s cornea actually look like?”
The resulting maps allow our optometrists to evaluate the pattern and distribution of corneal curvature.
For keratoconus and specialty contact-lens fitting, this information can be particularly valuable.
What Can Corneal Topography Tell Us?
Depending on the individual case, corneal topography can help our optometrists evaluate:
- Corneal curvature
- Areas of corneal steepening
- Corneal asymmetry
- Irregular astigmatism
- Patterns associated with keratoconus
- Changes in corneal shape between examinations
- Information useful for specialty contact-lens fitting
For a patient with keratoconus, this provides information that an ordinary spectacle prescription alone cannot provide.
The prescription tells us about the vision correction.
Topography helps us understand the shape we’re trying to fit.
Why Diagnostic RGP Fitting Still Matters
A sophisticated corneal map is extremely useful, but a computer doesn’t replace what happens when the actual lens is placed on the eye.
Specialty RGP fitting involves evaluating a diagnostic lens directly on the patient’s cornea.
Our optometrists assess factors such as:
- Lens centration
- Lens movement
- Stability
- Vision
- Comfort
- Relationship between the lens and cornea
One particularly important technique is fluorescein assessment.
What Is Fluorescein Assessment?
During RGP fitting, fluorescein dye can be used to help visualise the tear layer underneath the lens.
Under specialised illumination, the fluorescein pattern allows the optometrist to assess how the lens relates to different areas of the cornea.
This can provide information about:
- Central fitting relationship
- Areas of greater or lesser clearance
- Tear distribution
- Lens positioning
- Peripheral relationship
- Overall fitting pattern
The optometrist can then determine whether the diagnostic lens parameters should be modified.
This combination of corneal topography + diagnostic fitting + fluorescein assessment + visual evaluation is an important part of specialty RGP fitting.
Why Does RGP Fitting Take More Time?
Patients sometimes wonder why a keratoconus contact-lens fitting isn’t as quick as buying ordinary disposable contact lenses.
The answer is simple:
We’re fitting an irregular cornea.
The first diagnostic lens isn’t necessarily the final lens.
The optometrist may need to evaluate different parameters and determine how changes affect:
- Lens position
- Movement
- Corneal relationship
- Vision
- Comfort
Once an appropriate design has been established, a customised lens can be ordered.
Follow-up remains important because the lens must then be evaluated during actual wear.
For specialty contact lenses, the fitting process is part of the treatment journey.
Wöhlk KE vs Ordinary Soft Contact Lenses
| Feature | Ordinary Soft Contact Lens | Wöhlk KE RGP |
|---|---|---|
| Corrects ordinary myopia | Yes | Yes |
| Corrects regular astigmatism | Depending on design | Yes |
| Specifically designed for keratoconus | Usually no | Yes |
| Maintains rigid optical surface | No | Yes |
| Can mask significant anterior corneal irregularity | Limited | Yes |
| Individual specialty fitting required | Standard fitting | Yes |
| Corneal topography useful | Sometimes | Particularly important |
| Fluorescein fitting assessment | Usually not required | Yes |
| Initial adaptation | Usually easier | May require adaptation |
| Customisation | Depends on lens | High |
An ordinary soft contact lens largely conforms to the cornea.
For someone with a significantly irregular cornea, that can limit how much of the irregular optical surface can be neutralised.
The Wöhlk KE lens maintains its rigid optical surface, allowing the rigid lens and tear layer underneath it to help compensate for irregular corneal optics.
Wöhlk KE vs Scleral Lenses for Keratoconus
Wöhlk KE isn’t the only option available to someone with keratoconus.
Malaya Optical also provides scleral contact-lens fitting.
Scleral lenses are considerably larger than corneal RGP lenses.
Instead of primarily sitting on the cornea, a scleral lens is designed to vault over it and land on the sclera, the white part of the eye.
A fluid reservoir remains between the lens and cornea.
Both approaches can provide excellent visual rehabilitation for suitable keratoconus patients, but they achieve the fitting relationship differently.
| Wöhlk KE / Corneal RGP | Scleral Lens | |
|---|---|---|
| Size | Smaller | Larger |
| Basic design | Rests primarily on cornea | Vaults cornea |
| Landing area | Corneal | Scleral |
| Irregular cornea correction | Excellent in suitable cases | Excellent in suitable cases |
| Tear/fluid layer | Tear lens | Fluid reservoir |
| Handling | Small RGP lens | Different insertion/removal technique |
| Adaptation | May take time | Different adaptation experience |
| Fitting | Specialist | Highly specialised |
| Best choice | Individual assessment | Individual assessment |
Is Wöhlk KE Better Than a Scleral Lens?
Not necessarily.
This is an important distinction because people researching keratoconus online often search for the “best keratoconus contact lens.”
There isn’t one lens that is best for every cornea.
A corneal RGP such as Wöhlk KE may provide excellent vision, movement and performance for one patient.
Another patient may achieve better comfort, stability or visual performance with a scleral lens.
Factors such as:
- Severity of keratoconus
- Corneal geometry
- Cone position
- Lens stability
- Comfort
- Eye health
- Previous lens experience
- Lifestyle
- Handling ability
can influence the decision.
At Malaya Optical, our objective isn’t to fit Wöhlk KE simply because it is available.
Our objective is to determine which specialty contact-lens approach is appropriate for the individual eye.
Does Wöhlk KE Stop Keratoconus From Progressing?
No.
This distinction is extremely important.
Wöhlk KE and other specialty contact lenses are primarily used for visual rehabilitation.
They can improve vision by compensating for the optical effects of an irregular cornea.
They do not cure keratoconus, and an RGP lens should not be presented as a treatment that stops the underlying condition from progressing.
A patient can potentially achieve excellent vision with an RGP while the underlying corneal condition still requires monitoring.
Contact Lenses vs Corneal Cross-Linking
Another common source of confusion is the difference between specialty contact lenses and corneal cross-linking (CXL).
They serve different purposes.
Specialty RGP or Scleral Contact Lens
Primary purpose: improve vision.
The lens compensates for irregular corneal optics.
Corneal Cross-Linking
Primary purpose: stabilise progressive keratoconus.
Cross-linking is a medical procedure performed by an ophthalmologist to strengthen corneal tissue and reduce the likelihood of further progression.
A patient may therefore potentially need:
medical management to stabilise the condition
and
specialty contact lenses to provide better vision.
These aren’t competing treatments.
They address different aspects of keratoconus.
What If Malaya Optical Suspects My Keratoconus Is Progressing?
If our optometrists identify findings that suggest further medical investigation may be appropriate, we can refer the patient to an ophthalmologist or corneal specialist.
The ophthalmologist can then assess whether additional investigation or medical treatment, such as corneal cross-linking, should be considered.
This is an important part of responsible keratoconus care.
An optometrist fitting a contact lens shouldn’t ignore what may be happening to the underlying cornea simply because the patient can see well through the lens.
Can I Wear Wöhlk KE After Corneal Cross-Linking?
Potentially.
However, this needs to be determined case by case.
After cross-linking or another corneal procedure, our optometrists need to consider factors such as:
- Current corneal condition
- Severity of keratoconus
- Corneal geometry
- Healing
- Previous treatment
- Current vision
- Eye health
- Recommendations from the treating ophthalmologist
Some patients can successfully return to or begin specialty contact-lens wear after their cornea has been appropriately assessed.
Is Wöhlk KE Only for Severe Keratoconus?
Not necessarily.
The need for specialty contact lenses isn’t determined simply by whether someone has been labelled “mild,” “moderate” or “severe.”
What matters is the individual’s:
- Corneal shape
- Visual quality
- Irregular astigmatism
- Vision achievable with spectacles
- Lens fitting characteristics
- Eye health
- Visual requirements
Some patients with relatively early keratoconus may still experience significant visual distortion.
Other patients may continue to achieve useful spectacle vision for some time.
The individual assessment matters more than the label.
Are RGP Lenses Only Used for Keratoconus?
No.
Rigid gas-permeable and other specialty contact lenses can also be considered for selected patients with other forms of irregular corneal optics.
Depending on the individual case, this can include:
- Irregular astigmatism
- Other corneal ectasias
- Certain post-surgical corneas
- Corneal scarring
- Previous corneal trauma
- Other irregular corneal conditions
However, Wöhlk KE itself is specifically designed with keratoconus fitting in mind.
Patients with other irregular corneal conditions may require different lens designs.
“My Glasses Are New, So Why Is My Vision Still Blurry?”
This is something we want more people to understand.
If you have repeatedly changed your glasses but still experience:
- Ghosting
- Shadows around letters
- Increasing astigmatism
- Poor night vision
- Glare
- Distortion
- Vision that never seems completely sharp
it doesn’t automatically mean you have keratoconus.
However, these symptoms can justify a more detailed assessment—particularly if your prescription or astigmatism has been changing.
Corneal topography can provide information about the shape of the cornea that cannot be obtained simply by measuring spectacle power.
Growing Awareness of Keratoconus in Malaysia
Specialty contact-lens fitting isn’t new at Malaya Optical.
Our optometrists have been fitting RGP contact lenses for many years, and we also fit scleral lenses for suitable patients.
However, we’ve seen increasing interest in keratoconus and specialty contact lenses in recent years.
Greater public awareness, improved corneal imaging technology and easier access to information mean more patients now understand that poor vision with spectacles doesn’t necessarily mean there are no other vision-correction options available.
For someone with an irregular cornea, specialty contact lenses can sometimes make a substantial difference to everyday functional vision.
What Happens During a Keratoconus Contact Lens Assessment at Malaya Optical?
Every patient’s journey is different, but an assessment may include:
1. Understanding Your Eye History
We discuss your diagnosis, symptoms, previous spectacles, previous contact lenses, corneal procedures and visual requirements.
2. Vision and Refraction
Our optometrist evaluates your current vision and determines what can be achieved through conventional correction.
3. OCULUS Keratograph Corneal Topography
We map the corneal surface to better understand its curvature and irregularity.
4. Diagnostic RGP Assessment
An appropriate diagnostic lens can be selected according to the clinical findings.
5. Fluorescein Evaluation
Our optometrist assesses the relationship between the diagnostic RGP and the cornea.
6. Vision Assessment
We evaluate the visual improvement achieved through the diagnostic lens.
7. Lens Refinement
Parameters can be adjusted according to the fitting pattern, vision, movement and other clinical findings.
8. Lens Ordering
Once an appropriate design has been determined, the customised specialty lens can be ordered.
9. Insertion, Removal and Care Training
Our team teaches patients how to handle and care for their specialty contact lenses correctly.
10. Follow-Up
We reassess vision, comfort, lens performance, fitting and eye health.
Specialty contact-lens fitting isn’t simply:
“What is your prescription?”
It is:
“What is your corneal shape, what optical problem are we trying to solve, and how can we create an appropriate lens-eye relationship?”
Wöhlk KE Is Coming to Malaya Optical
Wöhlk KE Keratoconus RGP lenses are not currently available at Malaya Optical.
We are looking to introduce Wöhlk KE into our specialty contact-lens portfolio in the future, depending on patient interest and demand.
When introduced, we intend to make Wöhlk KE fitting available through our Malaya Optical locations:
- Jalan Imbi, Kuala Lumpur
- Damansara Uptown, Petaling Jaya
- SS15, Subang Jaya
- Bandar Puteri, Puchong
Because Wöhlk KE requires professional keratoconus assessment and specialty fitting, we do not plan to sell it as a direct online purchase through ShopMO.
Interested in Wöhlk KE?
If you have keratoconus and are specifically interested in Wöhlk KE, send Malaya Optical a message and register your interest.
Your enquiries will also help us understand demand as we prepare to expand our specialty contact-lens portfolio.
You don’t need to wait for Wöhlk KE, however, if you’re currently struggling with keratoconus-related vision.
Malaya Optical already provides RGP and scleral contact-lens assessments for suitable patients with keratoconus and irregular corneas.
Why Choose Malaya Optical for Keratoconus Contact Lenses?
Keratoconus isn’t an ordinary spectacle prescription.
And a keratoconus RGP isn’t an ordinary contact lens.
At Malaya Optical, our specialty contact-lens service combines:
- Qualified optometrists
- Experience fitting RGP contact lenses
- Scleral contact-lens fitting
- Keratoconus and irregular-cornea assessment
- OCULUS Keratograph corneal topography

Most importantly, we don’t assume every keratoconus patient should wear the same type of lens.
For one patient, a corneal RGP may provide excellent vision.
For another, a scleral lens may be more appropriate.
Another patient may first require assessment by an ophthalmologist.
We fit the patient—not simply the diagnosis.
Frequently Asked Questions About Wöhlk KE and Keratoconus
What is Wöhlk KE?
Wöhlk KE is a rigid gas-permeable contact-lens design specifically developed for keratoconus. It requires professional assessment and individual fitting.
Can Wöhlk KE improve keratoconus vision?
For suitable patients, an RGP lens can provide substantially better optical correction than spectacles by creating a regular front optical surface and using the tear layer beneath the lens to help compensate for anterior corneal irregularity.
Can Wöhlk KE cure keratoconus?
No. Wöhlk KE is intended for visual rehabilitation. It does not cure keratoconus or replace medical management when progression requires further evaluation.
Is Wöhlk KE a hard contact lens?
It is a rigid lens, but the more accurate term is rigid gas permeable (RGP). Modern RGP materials are designed to transmit oxygen.
Is an RGP better than a scleral lens?
Neither is universally better. Both can provide excellent visual rehabilitation in suitable patients. Corneal shape, severity, comfort, stability and individual requirements help determine the appropriate option.
Does Malaya Optical fit scleral lenses?
Yes. Malaya Optical already provides scleral contact-lens fitting for suitable patients.
Does Malaya Optical have corneal topography?
Yes. We use the OCULUS Keratograph to map and evaluate corneal shape.
Does wearing an RGP stop keratoconus progression?
No. RGP lenses improve vision but shouldn’t be considered a treatment for stopping keratoconus progression.
What happens if my keratoconus appears to be progressing?
Where appropriate, Malaya Optical can refer patients to an ophthalmologist or corneal specialist for further assessment.
Can I wear an RGP after corneal cross-linking?
Potentially, but this must be evaluated individually according to the condition of the cornea, previous treatment, healing and clinical findings.
Is Wöhlk KE available at Malaya Optical now?
Not yet. We are looking to introduce Wöhlk KE in the future based on patient demand.
Can I register my interest?
Yes. If you’re interested in Wöhlk KE, contact Malaya Optical and let our team know.
Better Vision With Keratoconus May Still Be Possible
Being told you have keratoconus can be worrying—particularly when your glasses no longer provide the clear vision you once had.
But an irregular cornea doesn’t necessarily mean you have to accept permanently blurry or distorted vision.
For suitable patients, specialty RGP and scleral contact lenses can provide a new optical surface over the irregular cornea and substantially improve functional vision.
Wöhlk KE will provide another specialty RGP option for us to consider when it becomes available at Malaya Optical.
But the first step isn’t choosing Wöhlk, RGP or scleral.
The first step is understanding your cornea.
