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.

Contact Lenses for Colour Vision Deficiency - Optometrist

Many of us may not aware that there is contact lenses for colour vision deficiency at Malaya Optical KL. Colour vision deficiency, commonly known as colour blindness, is a condition where an individual has difficulty distinguishing between certain colours. This occurs due to the malfunction or absence of certain types of cones in the retina, which are responsible for detecting colours. The most common types of colour vision deficiency involve red-green colour blindness, but there are also blue-yellow deficiencies and total colour blindness, though these are much rarer.

Prevalence and Causes:

Colour vision deficiency affects approximately 1 in 12 men and 1 in 200 women worldwide. The condition is usually inherited and is more common in men due to its linkage to the X chromosome. However, it can also occur due to aging, eye diseases, or exposure to certain chemicals.

This test involves identifying numbers or patterns within a series of coloured dot patterns.

A person with colour vision deficiency will not achieve a passing score while testing the Ishihara plates. After several examinations and once we have detected the issues, the patients will be given a pair of sample colour vision deficiency contact lenses depending on what type of colour vision defect they are. This can help us as an eye care practitioner to note down the number of plates a patient can perceive with and without wearing the colour vision deficiency contact lenses.
