Is the laser eye surgery dangerous?
Laser eye surgery is generally considered safe, but it should not compare it to "without risk", because all surgery involves risk. Although countless patients retired glasses or contact lenses with a vision of 20/40 or better, there are many considerations before you decide to laser eye surgery and not everyone is a candidate. In addition to complications, there may be side effects. Indeed, a small percentage of people see worse after laser eye surgery. The first step is to move the epithelium or the highest corneal layer. This can be done by techniques of "surface ablation" or "flap cutting". The second step uses an excimer laser to evaporate a small amount of tissue to transform the cornea to achieve the right vision. The Excimer Laser follows one of several technologies that differ in their ability to accurately map and transform the eye and carry different results. Both steps Carry their own related risks specific to the specific procedure used.
A good surgeon certainly helps ensure ABY laser eye surgery safer, but infection after surgery is always a risk and runs higher with surface ablation techniques, such as board and lasek verses cutting techniques such as lasic. Infections can usually be treated with drops and usually do not lead to long -term problems, although serious complications could cause temporary loss of vision or worse. The healing process associated with surface ablation techniques is longer and more unpleasant compared to the lassist.
Thecorneal boom is common after the surface ablation techniques, but usually disappears with time, although not always. Hazika cannot be repaired with glasses or contact lenses. Another laser procedure can be recommended using advanced technology, such as CustomVue Wavefront to target in scarring tissue.
LASIK THAT procedures Use a microcheratoma blade to cut the valve with the risk of cutting the valve instead of leaving it suspended. If the valve is irreparable or could occurunusual permanent damage or loss of vision. Even successful blade procedures can leave small imperfections or scars in the tissues of the cornea, which can lead to blurred vision - lack of crispy previously achievable by repair lenses. Advanced types of laser eye surgery can usually repair the imperfections created by a microcheratoma blade. (For example, CustomVue Intralasik uses a laser rather than a corneal blade, in addition to using advanced laser excimer techniques to target imperfections that have left other less advanced forms of laser eye surgery, making this form of laser eye surgery.
Due to the probability that a small amount of scar tissue can result from many types of eye surgery in 20/20, it may not be seen 20/20 as a vision of 20/20 has experienced before surgery with correction lens. Also, the risk of ending vision that is via corrected or under repair is not neoBirds, because the accurate reaction of the eye to laser surgery is unpredictable. In this case, it may still be necessary to wear glasses or lenses or to improve the result can be recommended for a second operation.
Some patients report sensitivity to light, glare, night vision problems and/or double vision problems after surgery. In most cases, these effects retreat over time, but there are no guarantees. The shape of the eye can also change as one aging, eventually requires a second procedure or use of glasses or contacts. The problem is not just, is a safe laser eye surgery, but are your expectations realistic?
various excimer lasers are approved by the FDA to work with certain technologies and for vision correction that falls within a specific extent. You can also learn more about the dangers of what you can look forward to before and after surgery and how to find a good doctor.
people who are pregnant, have diabetes, have problems with binocular seeIt has very dry eyes, thin cornea or very large pupils are just a few examples of those who are not good candidates for laser eye surgery. Before you decide whether to see if the laser eye surgery is safe for you, make sure your ophthalmologist to discuss the advantages and disadvantages of different techniques that relate to your specific needs.
