Orthokeratology—What is It?

Corneal Refractive Therapy is a non-surgical treatment that uses special contact lenses to reshape the cornea of the eye while you sleep, without altering the physiology of the eye.


This 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.


What To Expect From CRT?

Those who start CRT may begin to notice better vision in as little as just a few days, however, most patients will want to allow up to two weeks to gain the full results of treatment. It is important to note that the results of CRT are reversible and will only remain as long as the wearer continues the nightly use of the contact lenses.

CRT is a perfect solution for individuals who have mild to moderate nearsightedness, may not be candidates for LASIK surgery, or who do not want to undergo a surgical procedure to correct their vision. Patients who are active and wish to have sharper vision without having to worry about the daily use of glasses or contacts during the day have found CRT an ideal solution.


Dr. Bhakta at Planet Vision Eyecare can discuss whether CRT is appropriate for you. If you like the idea of waking up each morning with clearer vision without having to wear glasses or contacts during the day, call our Lake Worth eye doctor and find out more about how you can safely correct your vision – all while you sleep!


Is CRT Safe?

CRT was approved by the Federal Drug Administration in 2002 and has been approved for use in all ages of patients. While there have been no serious adverse risks related to wearing CRT lenses, those who have trouble using contacts should discuss their concerns with their eye doctor before proceeding with treatment.


How long do the lenses last?

Dr. Hetel Bhakta recommends replacing your CRT lenses once a year. During your visit to our Lake Worth eye care office, our eye doctors and orthokeratology experts will discuss with you the proper care techniques for your lenses so that they will last as long as possible.


Why Choose Orthokeratology?

For those with mild or moderate Myopia, Ortho-k is a great option, especially for sports-related activities or when working in environments containing debris or dust. Ortho-k can also be an effective pre-LASIK treatment that can temporarily stall the need for corrective eye surgery. In addition, the fast, painless and safe process makes Ortho-k a practical solution for children who have Myopia.


​​​​​​​How Costly is Ortho-k?

Unfortunately, most insurances do not cover the total cost of Ortho-k. Additionally, costs will vary depending on your eye doctor and your unique prescription. The general, two-set lens and appointment package can range anywhere from $900 to $1,800.
