The Orthokeratology Academy of America (OAA) is the leading body of orthokeratologists in the United States, formed to support, promote and advance orthokeratology(ortho-k) by providing quality education and scientific information on the subject of ortho-k to all its members. Dr. Abe is one of only fifteen Fellows in California. Less than one percent of U.S. optometrists have achieved Fellowship in the Academy. Fellowship status in the OAA is determined by doctor experience and expertise and follows a rigorous case evaluation and testing procedure. Those orthokeratologists who achieve Fellowship status are committed to adhering to the highest standards of care in this specialty.

Dr. Abe is proud to be the only Certified WAVE Contact Lens designer in the Bay Area and utilizes this advanced technology to custom design highly oxygen-permeable lenses including lenses for orthokeratology with astigmatism, hyperopic orthokeratology, myopia control, as well as for irregular corneas due to refractive surgery and for keratoconus.


Orthokeratology, or “ortho-k,” is the non-surgical process of reshaping the eye with specially-designed rigid gas permeable (GP) contact lenses. The goal of ortho-k is to reshape the front surface of the eye and thereby correct mild to moderate amounts of nearsightedness, farsightedness, and astigmatism. Other names for orthokeratology include CRT, corneal reshaping, corneal refractive therapy, and corneal molding among others.

*Many controlled clinical studies have continued to show that ortho-k can be effective in slowing or even halting the progression of juvenile onset or school myopia.*

How ortho-k works

The GP lenses for ortho-k are applied at bedtime and worn overnight. While you sleep, the lenses gently reshape the front surface of your eye (the cornea) to correct your vision, so you can see clearly without glasses or contact lenses when you’re awake. The effect is temporary – generally enough to get you through a day or two – so you must wear the reshaping lenses each night to maintain good vision during the day.

Who is a candidate for ortho-k?

Orthokeratology is frequently a good option for 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.

Ortho-k is particularly appealing for 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 ortho-k?

The goal for ortho-k is to correct your vision to 20/20 without eyeglasses or contact lenses during the day. In FDA trials of both CRT and VST 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 ortho-k 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 ortho-k.

How long does ortho-k take?

Though you may see some improvement in your vision after a day or two of overnight ortho-k, it can take several weeks for the full effect to be apparent. 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 ortho-k lenses.

Is ortho-k comfortable?

Some people have comfort issues when attempting to wear gas permeable contact lenses during the day. But since ortho-k GP lenses are worn during sleep, comfort and lens awareness are generally not a problem.

Cost of orthokeratology

Ortho-k 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, GP lenses used for ortho-k are more costly than most regular contact lenses. Therefore, fees for orthokeratology are higher than fees for regular contact lens fittings.

Can I have LASIK after ortho-k?

Yes, it’s possible to have LASIK surgery after orthokeratology. But because ortho-k 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 ortho-k lenses, so they can advise you how long you should wait before having the surgery.
