Risks with LASIK
You have probably spent ages agonizing over whether or not you should undergo a specific surgery, especially if it is an elective procedure and not absolutely vital to your good health. You are correct; it is not always an easy thing to decide upon. However, you should weigh the benefits and the detriments against your current health and the risk ratios that your physicians have come up with.
With LASIK eye surgery the most common risks that you can experience are undercorrection of the procedure, overcorrection of the surgery, failed surgery (which really just means that it was not a successful procedure) and even loss of sight. There are more effects that you are at risk to experience, but one of the first conversations you should have with your optometrist and physician is if you are healthy for this procedure regardless of the risks. If you are not healthy enough to qualify for this surgery, it is not a good option for you.
