For many years, people had to rely on eyeglasses to correct different eye conditions, such as nearsightedness, farsightedness and astigmatism. Modern contact lenses, however, were a game changer. They have allowed many people to see clearly without using traditional eyeglasses, but some don’t feel comfortable wearing them throughout the day. This led to the development of orthokeratology (ortho-k) lenses, which are only meant for overnight use.
Clear View Vision Care, a local eye clinic, discusses how ortho-k can help improve your vision.
What Is Ortho-K?
Refractive errors, such as myopia, hyperopia and astigmatism, are often caused by the irregular shape of the surface of the eye (cornea). With orthokeratology, the gas permeable contact lenses are used in corneal reshaping. This type of contact lens is highly porous, which makes it comfortable for overnight use. It’s also a good alternative for people who are looking for a way to improve their vision without surgeries.
Who Can Benefit From It?
Ortho-k lenses are most effective for people with nearsightedness, but they can also correct astigmatism, hyperopia and presbyopia. Children that are too young for LASIK and people who participate in contact sports are also good candidates for orthokeratology. Visit your local eye doctor to find out whether this corneal reshaping treatment is a good option for your eye condition.
What Are the Expected Results?
Your eye care specialist will aim for 20/20 vision after ortho-k, but 20/40 eyesight is an acceptable result. The latter is the legal minimum for driving in most states in the country. After wearing ortho-k lenses overnight, you can will have clearer vision for at least one day.
