When considering lasik surgery, it is critical to understand not just the potential benefits, but the risks involved as well. In this article, we will touch on some of the risks associated with having lasik surgery. In order to set your expectations and make the right choice, speak at length with your doctor until you fully understand all of the risks of lasik eye surgery.

20/20 vision is by no means guaranteed, particularly if your eyesight requires a high degree of correction. You may find after your initial lasik surgery that contacts or glasses or additional enhancements in the form of more surgery are required. Do not undergo the procedure with the expectation that your vision will be perfect afterward. It may be or it may not.

To maintain their health, your eyes require tears to keep them moist and comfortable. In some cases, patients develop chronic dry eye following lasik surgery due to their eyes being unable to produce tears sufficiently. While it is normal post lasik for your eyes to feel dry and require the use of drops, this condition can linger causing severe discomfort and requiring further treatment.

Seeing halos, starbursts and glares in darker settings such as at night is a possibility post lasik surgery. You may find yourself unable to drive at night without your eyeglasses. These issues may lessen as time passes or they may warrant additional surgery.

Lasik eye surgery is a newer type of surgery. The long term effects and effectiveness of the procedure are not altogether clear. You must be willing to accept the risk that comes with undergoing a procedure for which extensive data does not exist.

Most people who wear eyeglasses or contact lenses would be quite happy no longer having to rely on them all the time so the potential benefit of lasik surgery is easy to understand. It is extremely important, however, to understand the risks as well. If you are considering lasik eye surgery, speak with your doctor and weigh the potential benefits versus the risks before you make your decision.
