Most normal activities can resume within 48 hours. Those who receive PRK, however, can expect a longer recovery — about a month — and some minor pain due to the corneal surface removal. Although LASIK may cause dry eyes for up to three months and can be managed with artificial tears , the odds of it becoming a permanent issue are rare. Another uncommon side effect: nighttime glare or halos.
The treatment zone is much larger now, covering the entire cornea. Whether they choose LASIK or PRK, many patients view the prospect as life-changing — and a means to enjoy even basic activities that once were hindered by poor vision. Any trauma to a flap such as getting poked by a tree branch or fingernail could dislodge it — even years after surgery, Hood says.
At that time, he or she will confirm that your vision is within the legal standard for driving. At that visit, your doctor will determine if more follow-up visits are necessary. While you will be permitted to work the day after your procedure, it is recommended that you take a couple of days off to rest.
You should also refrain from strenuous exercise for the week after your surgery, as it can hinder the healing process. You should also avoid wearing eye makeup for a week, as well. Once you resume wearing makeup, you should use new products to avoid the risk of infection. These are given to help speed up the healing process, fight bacteria and infection, and combat dry eye syndrome. This is common and can take up to two weeks to resolve.
While your eye sight will likely be fuzzy and hazy initially, it should stabilize and continue to improve within the first few days after surgery. I usually ask patients to go home and keep their eyes closed for a few hours. After four to six hours, patients may feel relatively comfortable with their vision.
Most patients feel very comfortable with their new vision by the next day. However, this may depend on the severity of your eyesight prior to the procedure. Excimer lasers also can correct astigmatism by smoothing an irregular cornea into a more normal shape.
After the laser ablation reshapes the cornea, the flap is then laid back in place, covering the area where the corneal tissue was removed.
The flap seals to the underlying cornea during the healing period following surgery. LASIK laser eye surgery requires only topical anesthetic drops, and no bandages or stitches are required. Your eye doctor will perform a thorough eye exam to ensure your eyes are healthy enough for the procedure.
He or she will evaluate: the shape and thickness of your cornea; pupil size; refractive errors myopia, hyperopia and astigmatism ; as well as any other eye conditions.
The tear film on the surface of your eyes also will be evaluated, and a precautionary treatment may be recommended to reduce your risk of developing dry eyes after LASIK. Usually, an automated instrument called a corneal topographer is used to measure the curvature of the front surface of your eye and create a "map" of your cornea. With wavefront technology associated with custom LASIK , you also are likely to undergo a wavefront analysis that sends light waves through the eye to provide an even more precise map of aberrations affecting your vision.
Your eye doctor also will ask you about your general health history and any medications you are taking to determine if you are a suitable candidate for LASIK.
You should stop wearing contact lenses for a period of time advised by your doctor typically around two weeks before your eye exam and before the LASIK procedure. This is because contact lens wear can temporarily alter the natural shape of your cornea.
Before your LASIK surgery begins, numbing eye drops are applied to your eye to prevent any discomfort during the procedure. Your doctor may also give you some medication to help you relax. Your eye will be positioned under the laser, and an instrument called a lid speculum is used to keep your eyelids wide open.
The surgeon uses an ink marker to mark the cornea before creating the flap. A suction ring is applied to the front of your eye to prevent eye movements or loss of contact that could affect flap quality.
