Potential risks and complication of laser eye surgery
Except for visual benefits and technological improvements of laser eye surgery, there are still certain risks and complications of the surgery. Patients who are considering a laser eye surgery should be very clear of both the surgical options and potential risks through making a thorough discussion with the surgeon. Some problems are widely reported on corrective laser eye surgery.
In most cases, laser eye surgery can create clear vision and remove the need of eyeglasses or contact lenses. However, the surgery can not ensure a 100% success rate that there are still certain vision correction issues. It is hard to predict the level of effectiveness of a specific surgery. In very rare cases, some people report a worsened vision or little effect from the surgery. And some patients can still not get rid of corrective lenses.
Corneal haze is another side effect that occurs during the healing process of PRK or LASIK procedure. Corneal haze can cause a fuzzy and affect the vision. Fortunately, this condition is usually not serious and will go away on its own. No permanent visual effect will be left. However, there are also rare cases that corneal haze does not resolve itself, which requires further laser treatment.
Eye infections are also rare in laser eye surgery. Common consequences of an eye infection include discomfort and delayed healing process. Modern technologies can actually control the infection rate at a quite low level.
Halo effect is also one of the potential complications of LASIK or PRK procedure. It is widely known that halo effects usually occur in low light and dark conditions. Those LASIK recipients who suffer halo effect always have difficulty in night driving. Actually this effect is caused by the pupil enlarging.
Flap complications are only possible in LASIK recipients, because only LASIK cut a corneal flap during the surgery. Potential flap complications include damage to the flap and complete loss of the flap, which are caused by flap detachment or tearing.
Some patients also report that the visual effects of laser eye surgery gradually regress over time. In this case, a second surgery is needed.
