Eyesight problems such as nearsightedness, hyperopia, and astigmatism can be treated by a medical procedure generally known as LASIK, or laser eye surgery. According to the American Academy of Ophthalmology, laser eye surgery necessitates the usage of a laser to reshape the cornea in the front of a person's eye. When effective, this procedure improves the ability for the eye to focus on things. Nonetheless, there are several disadvantages to contemplate before experiencing this process.
As of 2010, there have been no medical studies to determine the long-term effects of laser eye surgery. The US Food and Drug Administration reports these possible dangers: visible disturbances, such as glare, halos and/or double vision; poor nighttime vision, and the improvement of severe dry eye syndrome (the individual cannot produce enough tears to keep the eye moist). The development of some of these symptoms is a risk each patient requires when undergoing laser eye surgery.
Laser eye surgery may not be as successful at correcting the eyesight as a man hopes. As an example, the American Academy of Opthalmology reports the patient's eyesight may be over- or under-corrected, that might require the patient to nevertheless wear eyeglasses or contact lenses. The US Food and Drug Administration notes the results are normally somewhat less great when the procedure can be used to correct large "refractive errors," significance vision that is exceedingly inferior. For patients who were originally farsighted, the outcomes of the process may diminish with age. Even if vision is 20/20 after the process, the person may have to use corrective lenses as he ages.
The FDA reviews that most health care insurance will not pay for laser eye surgery, meaning the cost for the procedure is out of pocket. This may be compared with the out of pocket price for contacts or eyeglasses, particularly when an individual has health insurance that can pay all or a percentage of those prices.
The FDA reports there are some signs that change the eyes one to three times post-operation and other symptoms that may continue around six months. The symptoms that most usually solve within a few days are light pain/suffering, burning, scratchiness and over-production of tears/watery eyes. Symptoms that generally solve between a month and one week are bad nighttime vision, glare, gentle sensitivity, fuzzy or blurred vision and dry eyes. There may be changes in eyesight up to half a year. There may also be a chance that the physician will recommend additional operation to fix issues or to enhance the vision correction.
