Who is a candidate for OVC?
- Nearsighted individuals who are too young for LASIK surgery or for some other reason are not good candidates for vision correction surgery. Because it can be discontinued at any time without permanent change to the eye, people of any age can try the procedure, as long as their eyes are healthy.
- People who participate in sports, or who work in dusty, dirty environments that can make contact lens wear difficult.
What results can you expect from OVC?
The goal for OVC is to correct your vision to 20/20 without eyeglasses or contact lenses during the day. In FDA trials of OVC lenses, more than 65% of patients were able to achieve 20/20 visual acuity after wearing the reshaping lenses overnight. More than 90% were able to see 20/40 or better (the legal vision requirement for driving without glasses in most states).
Success rates for OVC tend to be higher for mild prescriptions. Call our office to find out if your prescription is within the range that can be successfully treated with OVC.
How long does Overnight Vision Correction take?
- 1-2 days overnight for initial improvement.
- Several weeks for full vision correction.
- During this time, your vision will not be as clear as it was with glasses or contacts, and you are likely to notice some glare and halos around lights. It’s possible you may need a temporary pair of eyeglasses for certain tasks, like driving at night, until your vision is fully corrected by the OVC lenses.
Is OVC comfortable?
- Some people have comfort issues when attempting to wear gas permeable contact lenses during the day. But since OVC hard lenses are worn during sleep, comfort and lens awareness are generally not a problem.
Cost of Overnight Vision Correction
- OVC is a significantly longer process than a regular contact lens fitting. It requires a series of office visits and potentially multiple pairs of lenses. Also, hard lenses used for OVC are more costly than most regular contact lenses. Therefore, fees for OKC are higher than fees for regular contact lens fittings. The one time fee is less expensive than LASIK and depends on the complexity of the cornea.
Can I have LASIK after OVC?
- Yes, it’s possible to have LASIK surgery after orthokeratology. But because OVC lenses reshape your cornea, you must stop wearing the lenses for a period of time (usually several months) so your eyes can return to their original shape and stabilize. Be sure to tell your LASIK surgeon that you’ve worn OVC lenses, so they can advise you how long you should wait before having the surgery.
