When most people think of eye surgery today, LASIK is what often comes to mind. However, before LASIK, there was PRK (photorefractive keratectomy). PRK is still widely performed and differs from LASIK because it involves removing the top layer of the cornea instead of creating a flap.
While PRK might sound more intense than LASIK, it actually has a lower risk of complications. However, the recovery time is longer compared to LASIK.
Short-Term Recovery
PRK surgery is typically painless thanks to pain medication and numbing eye drops used during the procedure. The first 48 hours post-surgery can be uncomfortable, so doctors usually prescribe drugs like Vicodin and tetracaine drops to manage pain. For the next few days, patients should limit their physical activity and avoid straining their eyes, such as by reading or using computers.
Long-Term Recovery
About five to seven days after PRK surgery, the temporary bandage lenses are removed, and most patients can resume their daily activities. However, they should still avoid vigorous exercise and activities that could potentially injure the eyes, like boxing or karate.
One major difference between LASIK and PRK is the time it takes to see the surgery’s full effects. While LASIK patients often notice improvements within a week, PRK patients might need up to six months to fully appreciate the benefits of the surgery. During this period, their vision will improve, but it may not be perfect immediately after the surgery. It’s important for patients to manage their expectations accordingly.
A Patient’s Role in Recovery
To get the best results from PRK surgery, patients should actively participate in their recovery. Doctors often recommend taking Omega 3 supplements to prevent dry eyes and skin. Omega 3 is found in fish and can be taken as a pill or consumed by eating fish twice a week.
Patients should also avoid factors that can cause dry eyes, such as looking directly into fans or staring at screens for prolonged periods, especially in the first week after surgery.
Ongoing Recovery
Recovery from PRK surgery is a long-term process and might not progress as quickly as some patients hope. In rare cases, if the desired results are not achieved within six months, a second surgery might be necessary. This possibility is usually discussed beforehand, and reputable doctors often include this option in the treatment package at no extra cost. The recovery process for a second surgery is similar to that of the first one.
Even after successful surgery, patients need to continue protecting their vision. This includes using vitamins and supplements like Omega 3, keeping their eyes moist with drops, wearing sunglasses outdoors, and limiting screen time.
By following their doctor’s advice, patients who undergo PRK surgery can ensure they achieve satisfactory results for both themselves and their doctors.
