Photo refractive keratectomy, in short PRK is one of the common laser eye surgery for refractory errors such as hyperopia (farsightedness), myopia (Nearsightedness) and Astigmatism (Cross vision). PRK is well tolerated in patients with thin cornea. In PRK surgery, epithelium (outer membrane) of cornea is lifted and pre-determined layer of corneal cells are removed which exposes thick corneal part called ‘stromal bed’. Then surface ablation and corneal reshape is done by using laser according to patient’s vision prescription. The entire process will take just minutes to complete but recovery is more gradual, may take three to six months to achieve stable clearer vision.

PRK after care is an important phase in recovery. Instructions by surgeon should be followed as instructed.
As soon as PRK is done, your eyes is devoid of natural barrier ‘epithelium’ which will regrow in 2-3 days. So contact lens or eye dressing is often applied. Though it is an out-patient procedure, you may require to take rest for sometime. It is good to have someone to drive for you as your eyes are ideally should be kept closed for 3-5 hours after the surgery to make sure that healing process is not hindered.

In 1-3 days after surgery, there are some discomforts such as irritation, burning sensation, swollen eye lids, tearing and light sensitivity which are quite normal as a result of inflammatory process. Using prescribed steroid based eye drops will reduce these discomforts. Wash your hands before administering eye drops to prevent cross contamination. Put your drops while leaning back and gently close your eyes. Do not rub your eye at any cost. It is a raw force may disturb the epithelial growth.

Applying ice pack for every 20 minutes is effective to reduce discomfort especially burning sensation and swelling. Prevention of infection plays a major role in healing process. Administer antibiotic eye drops as prescribed for first 2 months after surgery. In 3-4 days, it is better to avoid strong wind and sun light. Sun glasses or protective goggles should be worn. During first week, Water should not get into your eyes. Very importantly the soap, face washing gels and shampoo are strong irritants  to inflamed eyes. So care must be taken while washing face and hair. Do not get dirt and dust into eyes. Sun glasses should be worn outdoor and indoor if necessary. Better to wear protective goggles at night and during sleep for at least 2-3 weeks. Some of you may get lot of crusting at the eye lash margins. This is probably a result of low grade eye lash infection. Use a warm wash cloth to remove the crust.

Swimming should be avoided for several weeks. You are required to refrain from strenuous physical activities, sports and other visual demanding activities as instructed by your surgeons. Dryness and decreased blinking reflex may continue for several weeks after surgery. So remember to blink frequently. Use of artificial tears is also recommended to keep your eyes hydrated. Smoky rooms and highly perfumed room sprays should be avoided. Glare and loss of contrast at night is a part of normal healing process. This will fade gradually in 5-10 days. If you are struggling more with blurred vision, contact your surgeon. There are some eye drops which can help you while driving. But should be used as prescribed. Depends on the vision prescription and age you may require to use eye glasses or magnifiers for certain activities like reading and driving till your vision gets clearer and stable.

Regular eye check ups are essential to track your progress and to address any complications at the earliest. Number of follow up visits are determined by your surgeon. Drink plenty of water will enhance healing and keeps you hydrated. Remember ‘Perfect Vision’ is an unrealistic, your goal is to see well enough and function without lenses for most distance activities. So remain positive to adapt to normal vision fluctuations and enjoy your new vision.
