What Are The Possible Risks Of Lasik Surgery?
Before you have laser eye surgery, you should be aware of the potential risks and side effects involved with any surgery. The chances of having severe vision-threatening side effects of laser eye surgery are very low. However, there have been a few cases of serious eye injury, requiring corneal transplant.
Excessive Corneal Haze Is a Common Occurrence After Laser Eye Surgery
Less than 0.1 percent of all patients suffer from corneal infection after Laser. This usually means an additional discomfort and slower healing, but no long-term effects after a number of years.
Under correction or overcorrection is also one of the most common side effects of laser eye surgery. A surgeon cannot predict precisely how your eyes will respond to treatment. This means you might need to keep wearing corrective lenses after surgery. In some situations, you can have another surgical procedure to improve the results.
After laser eye surgery, a few patients find their best-corrected vision withcontact lenses is worse than before. This is also one of the side effects of Laser eye surgery, usually resulting from irregular tissue removal.
Corneal haze is part of the normal recovering process after a laser procedure. It usually has no significant effect on your final vision and can be noticed only by an ophthalmologist with a microscope. However, in some cases, excessive haze can interfere with vision.
Regression is another possible side effect of laser eye surgery. For some patients, the eye returns to its initial state within a few months. A new surgical procedure is usually possible in such cases.
The halo effect can affect LASIK patients and is noticed in low light. As the pupil becomes larger, a second faded image forms due to the untreated part of the cornea. This can often interfere with night driving.
What Are Some of the Major Complications of Laser Eye Surgery?
Flap damage or loss is a more severe side effect of laser eye surgery. In some cases, instead of creating a hinged flap on the center of the cornea, the entire flap tissue comes off. This can usually be replaced after the laser treatment. However, in some cases, the flap can be damaged or lost.
A distorted flap is another side effect of laser eye surgery. It consists of a distortion in the shape of the cornea created during the healing process, which can result in a lower best-corrected vision.
Even when both the procedure and the healing process seem to go perfectly, there are some side effects that might still cause discomfort. Older patients, for example, cannot have both good distance and near vision in the same eye without wearing glasses or contact lenses. Patients suffering from myopia who could still read without glasses might no longer be able to do that after surgery. As with all surgeries, talking with your doctor before your procedure enables you to get a better understanding of the risks and complications that could occur with Laser eye surgery.
