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.
The health of the eyes and the general health of the individual must also be perfect. People who are myopic cannot undergo the process. They should allow enough time for their refraction to stabilize before undergoing the process. People with medical conditions such as glaucoma, arthritis, lupus, rheumatoid, diabetes, retinal disease, cataracts, and herpes infection of the eyes among others are not good candidates.
Several benefits are associated with this method, making it preferable. Firstly, it is perfect in producing results. Success rate in this process is over 96 percent. There is also the possibility of increasing the percentage by incorporating enhancements. The procedure is also painless because patients have numbing drops put in their eyes.
Results are achieved instantly in this process. It takes one day or less for the desired vision to be attained after surgery. The process does not involve stitches and patients do not wear bandages. Loss in vision that occurs with age after surgery can be corrected through adjustments in the process later on. People depend on contact lenses and eyeglasses less after undergoing the process.
Certain disadvantages are also associated with this surgery too. To begin with, it is a technically complex process. Although rare, mistakes can occur, which may cause irreversible damage to vision. Other risks associated with the procedure include vision loss, severe night vision problems, decrease in contrast sensitivity, and severe dry eye syndrome.
