If you are planning to be free from glasses or contact lenses, then laser eye surgery is the thing for you. However, being zapped with high energy lasers has its price and it is not just about the money. Laser eye surgery complications can affect anyone who decides to undergo this sort of procedure and one should be fully aware and prepared for such risks, otherwise it could lead to some very nasty surprises.
By far, the most universal laser eye surgery complication is constant dry eyes. This is caused by the laser itself that not only burns off the inner corneal tissue, but also severs the corneal nerves that supply the tear glands. This results in a lack of feedback to the brain, which would normally signal the production of tears, and then dry eye syndrome occurs. Eye drops prescribed to you after laser eye surgery should be used to alleviate the symptoms of dry eye, such as pain, itching, burning, a sensation of something in the eye and a feeling of the eye sticking to the eyelid. If you still experience persistent dry eyes after 6 months after surgery, then it is likely to be a permanent side effect. Regular visits to the doctor prior to 6 months after surgery should have preceded such incidents from occurring.
Another one of the most common laser eye surgery complications is debilitating eye conditions. This manifests itself as night glare, haloes, starbursts and ghost vision. Night glare is the enhanced glare effect at night, which often means an increased recovery time to glare. This results in increased glare effects and makes it very difficult to see at night, especially in the presence of light. Haloes also happens around lights and it usually shows itself as halo rings around these lights. Starbursts are similar to haloes except that the lights appear to exude a sparkling or excessive shining effect, in the same way an especially bright star in the sky would appear. Ghost vision essentially results in double vision and creates something of a dazed effect. All of these symptoms are often in combination and can severely affect the patient's vision, especially at night. It may take some time to fully recover, probably about several months, before these symptoms veryly subside.
Under correction or over correction can also occur as a complication of laser surgery. In any case, this is due to the patient's healing rate, since it varies from person to person. Any difficulties in seeing clearly without glasses or contact lenses should be rectified with wearing glasses or contact lenses of a weaker prescription. The patient should also wait for their prescription to stabilize before before further eye surgery to completely correct their eyesight.
These are some of laser eye surgery complications that you can expect to experience after the surgery. With proper planning and knowledge, it should be reasonably possible to address any adverse effects of laser eye surgery and to achieve perfectly clear vision.
