PRK: A LASIK Alternative
PRK (photorefractive keratectomy) is a vision correction procedure that has been performed since 1995 to correct nearsightedness, farsightedness and astigmatism. The precursor to LASIK, this procedure is still performed today on patients who are not LASIK candidates due to thin corneas or other conditions. Even if you have been turned down for LASIK, you may still be able to achieve clear vision through PRK.
Like LASIK, PRK involves the use of an excimer laser to reshape your cornea, allowing light to properly focus on the retina (the back of the eye) for clear vision.
How PRK Differs from LASIK
Dr. Pernelli utilizes the same technology for PRK as he does for advanced iLASIK surgery; however, the first step is somewhat different. Rather than creating a flap on the corneal surface, David R. Pernelli, MD, gently removes the outermost layer of corneal tissue (epithelium) using the iFS Advanced Femtosecond Laser to allow bladeless access to the underlying corneal tissue for the reshaping process.
The remaining steps for reshaping the cornea are the same and also use the WaveFront guided technology and the Star S4 IR Excimer Laser with Activetrak technology to provide superior results.
Recovery is slightly longer than with LASIK because the eyes need time to regenerate the epithelial layer on the cornea. Most people demonstrate very similar outcomes to those who have Advanced LASIK surgery performed.
“I have performed LASIK surgery on two nephews and PRK surgery on my younger son – all on the same day – and their visual outcomes have been virtually the same.”
Is PRK Right for You?
The only way to find out if LASIK or PRK is right for your eyes is to have a comprehensive exam by an ophthalmologist. Generally, if you have overall healthy eyes, a stable vision prescription and are at least 18 years of age, you may be a good candidate. Your corneal thickness and eye health must be examined in depth to determine your candidacy.
