For people that are tired of using glasses or contacts, it might be time to consider the procedure known as LASIK. It is a form of refractive surgery which in full denotes laser assisted in situ keratomileusis. Even people who undergo this procedure might still need glasses when they drive at night or when they need to read as they age. In considering LASIK San Antonio TX residents need to know what the procedure involves.
The outcome of the procedure is dependent on an individual and their refractive error. Other factors also affect results. People who suffer from moderate or mild nearsightedness get the best outcomes after Lasik procedures. If degree of nearsightedness is considerably high, or for people with astigmatism and farsightedness, results are less predictable. Usually, images within eyes are formed on the retina which is found at the back of eyes. If one suffers from near or far sightedness, these images are focused elsewhere, leading to blurriness in vision.
Individual specialists may specialize in different types of LASIK procedures. The difference in the procedures is minor and none can be said to be superior to the others. There is photorefractive keratectomy, PRK, in which the top surface of the cornea is scrapped away rather than forming a flap. The corneal abrasion will take several days to heal, which will result in moderate pain and blurred vision for a short time.
In general, laser surgeries will be most suitable for people with moderate level of refractive error. In addition to that, they must not have any other unusual problems with vision. Your surgical practitioner will ask questions about the eyes and general health. This is done to confirm that there are not conditions which may bring about complications. The conditions of eyes that may lead to complications are dry eyes, eye injuries and large pupils among others.
Those with large pupils are not the best candidates for LASIK since surgery will most likely lead to debilitating symptoms like glares, star bursts and halos. They could also see ghost images. If you have fairly good vision and you are still able to see properly using contacts or glasses, you may not need to go for Lasik, more so given the possible complications. Individuals taking part in contact sports like martial arts or boxing should also avoid Lasik treatment.
There are possible side effects and complications. One of the common ones is dry eyes in which there will be temporary reduction in production of tears. For the first 6 months following surgery, the eyes might feel unusually dry as healing takes place. Even after complete healing, there might still be a level of dryness.
There is also possibility of under corrections or under correction. If lasers remove very little tissue from the eyes, you might not get the best outcomes. Under corrections mostly happen in those that are near sighted. If too much tissue is removed, there will be over correction. It is more difficult to correct that under corrections.
The majority of persons that go for LASIK treatments end up with perfect vision. The results will stay for many years or decades. With time however, vision tends to deteriorate as refraction worsens. The vision will no longer be as excellent as it was after treatment.
