The eyes are numbed entirely with a topical anesthetic eye drop. During the surgery, people cannot feel anything that is happening while the laser is reshaping their cornea. They see a flurry of lights but feel nothing.
Following PRK the eyes may feel irritated and sensitive to light. This starts once the numbing drops have worn off 20 minutes after surgery and lasts days until the eyes have healed. After the PRK surgery is complete, the surgeon will place a Contact Lens over the eye to act as a shield protecting the eye as it heals. The Contact Lens will help to decrease the discomfort otherwise felt, and help the eye to heal faster.
Instead of taking the contact lens out every night, like a normal lens, this Bandage Contact Lens stays in the eye until the surgeon removes it once the eye has healed, days after surgery. For some people, the irritation following PRK is mild and does not stop them from doing the things that they would normally do. Others will prefer to stay inside in dim light until the eyes heal.

Vision will be improved immediately following surgery, but it will get even better in the coming weeks. As the effects of the numbing eye-drops wear off, people may experience moderate discomfort in the eye.
Other side-effects can include sensitivity to light, tearing, blurry vision, a sense of burning or dryness, and itching. These symptoms may last for three to five days as the eye heals. Medicated eye drops are used during this time to prevent infection and inflammation.
Discomfort during this phase is common and usually can be managed with over-the-counter painkillers and preservative-free artificial tears. Patients should avoid exercise during this time, and wear polarized UV blocking sunglasses while outside.
Around day five, the surface of the cornea will complete its healing. The procedures also differ in terms of recovery time and side effects. People having PRK can also expect to feel more discomfort afterward and experience more side effects, such as corneal haze. Deciding between the two can be difficult unless you have specific conditions that require that you do one or the other.

Someone may also choose PRK if their profession causes them to be at much greater risk of getting hit in the eye and causing flap movement e. Both procedures are also equally safe—the main differences are the time it takes to heal and frequency of post-surgery visits.
