I was wondering what are the risks or side effects of refractive surgery and how common are they?

Need Thorough Eval: The most important part of the process is the screening. A thorough evaluation is done to make sure you are a good candidate. Most common risk is dry eye, glare, halos which usually lasts a few weeks to months. Some risk for infection and inflammation that can be treated. Risk for requiring an enhancement if your prescription is not fully treated. Rare risk of ectasia ( warping of the cornea).
