Another blade free laser vision alternative is a procedure called PRK or Photo Refractive Kertectomy. PRK has been performed in the United States since 1995 and was the first laser refractive procedure approved by the FDA. It was considered the most common refractive procedure prior to its predecessor LASIK. Both LASIK and PRK are considered laser vision correction procedures. PRK delivers the same visual results as LASIK but with a slightly longer recovery time.
A common misconception has been that patients with Astigmatism cannot have these procedures. Very early in laser vision correction’s history this was correct, however, technology has become so advanced that patients with nearsightedness, farsightedness, astigmatism or a combination can all benefit from laser vision correction with the VISX Star S4 Laser. Scheduling a complete dilated consultation with Dr. Herschel will allow you the opportunity to find out which procedure will give you your personal best vision.
With all laser vision correction procedures, there are two steps. The first step is in preparing the cornea, the front of the eye, to be treated. The second step involves the use of an excimer laser to reshape the cornea so light will focus properly into the eye and on the cornea to create clearer, better vision without glasses or contact lenses. The difference between PRK and LASIK is in the first step. With PRK there is no corneal flap created as in LASIK and the full treatment is placed on the surface of the cornea. Any complications which can arise during the creation of a corneal flap are eliminated when having PRK. This often provides a comfort level to many patients who have been hesitant to move forward with the LASIK procedure.
During the PRK procedure the Herschel Lasik team will walk you through every step. They will coach you from beginning to end. You will lie down in a comfortable reclining chair and be positioned directly under the laser. You will be given a series of eye drops, one of which will numb your eyes. An eyelid holder will be gently placed between your lids to help keep you from blinking. The doctor will ask you to look at a target light for a short time while the VISX Star S4 excimer laser sends pulses of light to the cornea to painlessly reshape the cornea. The laser treatment generally takes less than a minute. Once the procedure is completed, the Lasik team will escort you into an exam room to rest momentarily before Dr. Herschel returns to review your post operative instructions with you and any person who may have accompanied you that day. These instructions may include having a bandage contact lens in the eye to encourage more rapid healing and getting plenty of rest over the next couple of days.
If you are considering PRK, it is important to consider that Dr. Herschel was involved in coordinating the stage III FDA trials on Myopic (nearsighted) PRK and later, hyperopic (farsighted) PRK while working with the world renowned Dr. Marguerite McDonald. Also consider Dr. Herschel is a corneal specialist who has performed thousand of vision correction procedures and continues to offer his patients the most advanced vision correction options available.
