We’ve been there: we’ve lost a contact on vacation and forgotten to pack extras, broken our glasses when the baby took them off the table and left them on the floor. We’ve even lost our beloved (and expensive) prescription sunglasses at a day on the lake. Sometimes the hassle of glasses or contacts gets to the best of us, which is why we at Thom Eye and Laser Clinic are proud to offer Retinal laser surgery to help correct astigmatism (usually caused by an irregularly shaped cornea in the eye), myopia (commonly known as nearsightedness), and hyperopia (farsightedness). Interested in having one of these problems corrected? Keep reading to learn the basics of Retinal Laser Surgery and how it differs from LASIK surgery.
It’s likely that you’ve heard of LASIK surgery, but did you know that Retinal Laser Surgery (also known as PRK, which stands for photorefractive keratectomy) is actually older than LASIK? Yes, PRK was a precursor to LASIK surgery, but that doesn’t mean it’s outdated. Actually quite the opposite: PRK is best suited for certain eye issues.
How are they similar?
Both PRK and LASIK aim to correct vision problems via the use of lasers. They reshape the cornea so light entering the eye can be properly focused on the retina (resulting in clearer vision). Often, the vision results are similar in patients after either surgery is performed.
How are they different?
Depending on your eye health, you may not be a good candidate for LASIK surgery. Essentially, to be a good candidate for LASIK, your eyes must have a certain amount of cornea thickness. PRK is suitable for patients who may have a thinner cornea than LASIK requires, as the procedure doesn’t create a corneal flap on the patient’s eye.
Recovery time for PRK may be longer than recovery time for LASIK, since the eye must regrow epithelial cells after the procedure. Patients who have had LASIK may recover their vision quicker, though PRK patients do not have the risk of flap complications.
