Any age restriction for Ortho-k?

No, both adults and children can wear Ortho-K lenses. The youngest patient we have was 6 years old, her mother worked with her every night and after 2 months, this cute girl was able to insert and remove the lenses by herself under her mom’s supervision. Also, we have few people in their 40’s and 50’s who love the freedom that Ortho-K brings to them. One eye was corrected for distance vision and the other for reading, this is known as “monovision”.

How quickly is my vision to improve with Ortho-K?

Your vision will improve after the first night and it will improve further and stabilise over the next two weeks of Ortho-K wear because your eye shape remodel with the treatment. For higher degrees of short-sightedness and astigmatism will take longer time to achieve optimum vision.

What prescriptions are suitable for Ortho-K?

Ortho-K typically works best for myopia (short-sightedness) between -1.00 to -6.00. The amount of astigmatism reduction depends on the type of astigmatism and amount. The upper limits for astigmatism reduction are 1.50 diopters of “with-the-rule” corneal astigmatism and 0.75 diopters of “against-the-rule” corneal astigmatism. Ortho-K will not have an effect on the internal astigmatism.

Conjunctivitis or Pink Eye - Optometrist

Conjunctivitis, or pinkeye, is an inflammation of the membrane covering the inside of your eyelids and the outer part of your eye. It is generally not serious but can be highly contagious.

Conjunctivitis often feels like you have something in your eye that you can’ t get rid of. There are many causes of conjunctivitis. Viruses are the most common cause. Other causes include:

Allergies (allergic conjunctivitis)
Bacteria
Certain diseases
Chemical exposure
Chlamydia
Fungi
Parasites (rarely)
Use of contact lenses (especially extended-wear lenses)

“Pink eye” refers to a viral infection of the conjunctiva. These infections are especially contagious among children.

Newborns can be infected by bacteria in the birth canal. This condition is called ophthalmia neonatorum, and it must be treated immediately to preserve eyesight.

Conjunctivitis is generally not a serious problem and often will go away by itself. You should still, however, see your doctor. Chronic conjunctivitis, if left untreated, can cause permanent eye damage.

Treatment

Treatment varies depending on what is causing the inflammation. Bacterial conjunctivitis is generally treated with antibiotic eyedrops or ointment. Viral conjunctivitis does not respond to antibiotics, but antihistamines and anti-inflammatory medications may help relieve your symptoms. Warm or cool compresses may help reduce itching and swelling.

Drug Therapies

Viral conjunctivitis: Generally, your doctor will let the virus run its course. Your doctor may prescribe antiviral eyedrops, such as acyclovir (Zovirax) or trifluridine (Viroptic). Treatment is supportive and may include ocular decongestants, and artificial tears. Cold compresses applied 3 times daily for 1 – 3 weeks may relieve discomfort.

Allergic conjunctivitis: Your doctor may recommend allergy shots over several months, to reduce your sensitivity to the allergen. Antihistamine eyedrops, such as over-the-counter antazoline phosphate (Vasocon-A) or prescription olopatadine ophthalmic (Patanol), may reduce swelling or itching. An oral antihistamine can help relieve itching. A cool compress may help relieve symptoms, too.

Bacterial conjunctivitis: is treated with antibiotic eyedrops, such as sodium sulfacetamide (Cetamide, Bleph-10), or azithromycin, or ointment such as erythomycin (E-Mycin), bacitracin, or neomycin.
