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.

Nikon Lens Coatings - Optometrist

Nikon lens coatings that are available are SeeCoat Blue and SeeCoat Plus UV.

Today’s eyeglass lenses are almost all made from an organic material called plastic resins which are lightweight and relatively impact resistant. Plastic Resins is different from ordinary plastic material due to their optical and mechanical properties.

Plastic Resin have a high purity and have the capacity to be polished with accuracy, resulting in greater transparency. They also include fine chemical components that yield high refraction indexes. This results in thinner lenses with protective properties such as UV cut.

However , if ever the lens can be scratch easier and it will cause reflection for wearers. In Nikon, to treat the lens, numerous coatings is applied on the surface of the lens. Up to 15 layers on each side is treated in order to maximise the performance. The base of the lens treatment is the varnishing hard coat layer. It protects your lenses from scratches.
