LASIK safer than contact lenses

Written By: | December 20, 2011

A review of recent research has led investigators to conclude that LASIK may be the safer option, especially in the long run.

Like any surgery, LASIK has its risks, including fluctuating vision, dryness and halos, particularly during the early healing period. However, the risk of significant loss of vision was calculated at 1 in 10,000 (0.01%).

The risk for developing a serious contact lens infection was calculated to be significantly higher, at approximately 1 in 100 (1.0%) over 30 years of use, with the risk of serious vision loss at 1 in 2,000 (0.05%).

Direct comparison is difficult, as complications due to surgery usually are noted shortly after surgery, whereas the risks associated with contact lens wear – eye sensitivity, chronic allergies, dry eye syndrome, contact lens intolerance – accumulate over years. Unsafe practices, such as wearing contact lenses overnight, using contacts longer than recommended, or using tap water to store contacts can significantly increase the risk of infection and other complications.

For these reasons, contact lens are considered a medical device by the FDA and a yearly examination is required for renewal of contact lens prescriptions.
