Myopia and Overnight Vision Correction
Let’s begin with “Myopia.” Exactly what is it?
Myopia is the medical term for “nearsightedness,” a condition affecting nearly three million Americans a year, where a refraction error of the cornea hinders light to bend properly, making objects far away appear blurry. While this condition is technically chronic, recent advancements in the eye industry have made it possible for people with low Myopia to temporarily correct their vision through a process called Orthokeratology, or “Ortho-k.”
Orthokeratology—What is It?
Orthokeratology is a form of reversible, refractive correction involving the overnight use of gas-permeable contact lenses to reshape the contour of the cornea while you sleep. These oxygen-intense, “breathable” lenses work to temporarily reverse the effects of Myopia during the night so the wearer can experience clear vision the following day without the use of glasses or contacts. Ortho-k is used primarily to slow the progression of mild Myopia in adults and children, although it can aid in the temporary correction of low-degree astigmatism, hyperopia, and presbyopia as well.
The Orthokeratology Process
Orthokeratology involves a three-step process:
1. Initial examination,
Corneal Topographer will be used to determine the shape of your cornea and measure the refractive error of the cornea.
2. Fitting & Training,
We will order a set of lenses based on your corneal measurement and your eye sight strength, we will walk you step by step through insertion and removal procedure and explain in detail about all the solutions and eye drops that you need.
3. Treatment phase & Follow Ups,
Candidates use their prescription Ortho-K contact lenses while sleeping for at least six to eight consecutive hours each night and return for evaluation in one-to-two-week. Candidates may need to wear disposable soft lenses or glasses throughout the day during the correction phase. On completion of the treatment, only the prescribed overnight contacts need to be worn.
Remember, there is always the risk of infection without proper eye and lens care, so practice good hygiene and schedule routine follow-up eye appointments!
We anticipate an initial treatment period of three months. Most patients will be able to see comfortably within the first 72 hours of treatment without additional correction, however, full treatment may not be achieved for 1-2 weeks.
Am I a Candidate for Ortho-k?
The best candidates for Orthokeratology are children between the ages of eight and 12 who have progressive Myopia. If early stages of nearsightedness are caught soon enough, Ortho-k can sometimes help with restoring vision in children, because the custom lenses “mold” the eyes overnight to hinder or encourage the growth of cells. Ortho-k also works well with adolescents and young adults with mild or moderate Myopia, or for adults under the age of 40 who aren’t interested in LASIK or other eye corrective surgery. If you suffer from Dry Eye Syndrome or have severe Myopia, Ortho-k is not recommended.
If you have any questions and would like to learn more about Ortho-k, schedule an appointment with EyeClinic Medical.
Our eye care professional Dr. Hamid Hashemi will be able to help you determine your candidacy, costs, benefits, and risks of the process.
