LASIK is the acronym used for laser in-situ keratomileusis. As popular surgery, this method is used to correct vision for patients with astigmatism, nearsightedness, and farsightedness. When one is looking for surgeons who have specialty in LASIK eye surgery San Antonio offers the best place to consider visiting. San Antonio is home to several eye doctors with a lot of experience and specialty in this process.
In most surgical procedures that use laser to rectify vision, reshaping of corneas is the primary concept relied upon. The correction of cornea is done to allow for the focusing of light on retinas correctly. LASIK achieves perfect focusing of light going through the cornea onto the retina. From the retina, focused light can then be passed into the brain through the nervous system for processing.
This kind of surgery has been done on many people with successful results being achieved. However, it is not a procedure that can be done on everybody. There are certain prerequisites that need to be fulfilled in order to qualify as a candidate for the process. The first requirement is that one must be over the age of 18 years. Some surgeries require people to be over the age of 21 years.
Candidates must be 18 and above because the vision of younger people continues to undergo changes up to or over that age. At the time of surgery, the individual must not be pregnant or nursing. The measured refraction of eyes is usually affected by pregnancy or nursing of babies. Oral prednisone, Accutane and other prescription medicines also make people who are taking them unsuitable for surgery.
Healthy eyes and good general health are two major requirements. If one is myopic, they cannot undergo the process. Refraction in their eyes must be stabilized first prior to surgery. There are certain medical conditions that exclude patients from being good candidates. These conditions herpes infection of eyes, include retinal disease, cataracts, glaucoma, rheumatoid, diabetes, arthritis, and lupus.
There are several advantages associated with this surgical procedure, making it very recommendable. The first benefit is that it functions perfectly. It has been determined that about 96 percent of all patients attain the vision they desire after undergoing the process. This number can be increased with further enhancements. During the process, numbing drops are dropped into the eyes, which makes the whole process very painless.
This process is very instant in producing results. Correction in vision is achieved immediately after surgery or one day afterwards. No stitches are involved and there is no need for wearing bandages. Since vision is prone to continue changing with age, adjustments can be done later to correct effects to vision caused by aging. Dependence on eyeglasses and contact lenses is often reduced a lot.
This surgery is not all perfect because it has some disadvantages associated with it too. First of all, it is a very complicated process that needs a lot of skills to execute successfully. In case of a mistake, the damage it causes to vision cannot be reversed. Additional risks associated with the process include vision loss, decrease in contrast sensitivity, severe dry eye syndrome, and severe night vision problems.
