Risks and side effects of LASIK

As with any surgical procedure, LASIK surgery has some possible risks and side effects that must be taken into account. A specific end result cannot be guaranteed, although it can be closely predicted based on data from thousands of previous cases. Side effects are usually minimal following LASIK surgery. During the first few days after surgery, most people can expect to experience at least some of these effects:
• Increased sensitivity to light or glare.
• Gritty and burning sensation in the eyes.
• Slightly drier eyes.
• Decreased visual clarity in dim light.

In most cases, these effects decrease and eventually disappear as the eye heals. Occasionally, some may persist.
Serious complications are fortunately very rare. Some of these include infection, wrinkles in the flap, epithelial in growth and increased or decreased response to correction. These complications are treatable with medication or further surgery.
