What is vision correction? Vision correction is a sub-specialty of ophthalmology which employs various techniques to improve the natural focusing power of the eye for patients interested in reducing their dependence on glasses or contact lenses. This is called refractive eye surgery.

The two most common techniques are radial keratotomy (RK) and photorefractive keratectomy (PRK) and both change the curvature of the cornea. To become better acquainted with us be sure to familiarize yourself with our qualifications and accomplishments, and the various refractive surgery procedures available at the American Eye Institute.
If you are thinking of vision correction surgery, trust your
eyes to surgeons with experience, integrity, and academic
reputation. The American Eye Institute (AEI) includes
ophthalmologists who have had over 15 years experience in the
specialty of vision corrections surgery (refractive surgery).
This includes 15 years experience with radial and astigmatic
keratotomy (RK and AK) and 5 years experience with
photorefractive keratectomy (PRK). They were the first surgeons
on the west coast to perform PRK for the correction of myopia in
normal eyes. The refractive surgeons of the AEI have achieved
national and international reputations in the field of vision
correction.
