Even if the promised good view everything else pushed in the head, they should ensure that they also consider the risks of Lasik surgery. In the worst case threatens the patient with a loss of vision.
As with any medical procedure there are also a Lasik surgery risks that one should be familiar with before the surgical correction of poor eyesight. Most of the existing figures is from clinics that offer LASIK surgery. This type of self-interest to a high success rate.
The Lasik surgery is still a relatively new process that is only practiced since 1998. Since the surgery technology is constantly being improved and developed. Therefore, statistics must be subject to the success of the operation which has been in the first years of application of the technology created in the U.S. Some of the complications that occurred were due to human error, since the surgeon often due to lack of experience made mistakes.
Statistical risk due to low modern methods
LASIK surgery is the risk of complications during and after the procedure, less than one percent. During surgery, a section of wafer-thin flakes removed the upper cornea and folded aside. After grinding the underlying cornea, the cornea covering elk back down and immediately sticks. Some of the risks involved are the necessary interface in this context, for example, the risk of infection.
Risk factor high refractive error
Overall, this form of eye surgery is very safe. The actual complication rate is also very low due to the good advice before the procedure and the proper screening. Most complications occur in previously high refractive error, i.e., with a myopia of less than -8 diopters and hyperopia in a more than +3 diopters. Therefore recommend reputable clinics in some cases on an operation. Also cracking the edge of the retina, increased eye pressure, or rheumatic diseases are arguments against an intervention, because patients would otherwise run the risk of irreparable deterioration of vision.
More complications arise in patients aged over 40 years. People who are older than 45 years need glasses as age vision problems are not resolved by Lasik surgery. Generally, the probability after a LASIK treatment still needed glasses or contact lenses, is in five to ten percent.
