Elimination Of Eye Problems By Getting Eye Surgery
Science and technology go hand in hand when it comes to innovation of new techniques. We have seen enough miracles of science and technology in the last couple of years and continue to do so. One such area where this amalgamation has produced happy results is human body. Earlier, a man had to suffer loss of vanity due to weak eyes. Putting on eye glasses caused headaches, putting on lenses may improve the looks but it is tiresome putting them on everyday. Those problems have been exterminated with the mixing of computer technology and medical science. Now you can think about getting eye surgery done and regain strong sight.
Laser and non-laser eye surgery are well known and popular means of improving your eye sight and regaining the lost focus. In laser surgery, a laser is used as a means for reshaping cornea. LASIK, LASEK, PRK and Intra Lenses are the types of refractive laser surgeries one can choose from to improve their vision.
LASIK treats nearsightedness as well as farsightedness apart from astigmatism. During LASIK surgery, the surgeon uses an excimer laser, makes the flap at the outer and middle layer of cornea and removes the tissue under the flap. LASIK surgery takes around a minute to finish per eye. IntraLense is closer to LASIK with the only exception being, an additional laser is being used in place of a blade to cut the flap in the outer layer or epithelium.
LASEK is quite similar to LASIK with the only difference being here the flap is cut not from the middle layer of the cornea but only the epithelium. Patients with thin cornea should go for LASEK surgery despite the fact that it causes more discomfort than LASIK and the patient needs some time to heal.
PRK or photorefractive keratectomy cures one of mild to medium farsightedness and nearsightedness as well as astigmatism. To correct the vision, all the surgeon needs to do is remove the tissue from the epithelium. He doesn’t need to cut flap in this case. Such surgery takes around a minute and doesn’t need much time to heal.
Non Laser Eye Surgery involves the usage of low heat radio waves or cutting of surface of the eye to reshape the cornea. Non laser eye surgery includes methods like implantable and no maintenance contact lenses that are put behind the iris. These are used for curing severe cases of nearsightedness and farsightedness. One needs around 20 minutes to get this surgery done.
Another method is getting intraocular lenses implanted while removal of cataract, replacing the natural lens. It cures mild to medium cases of near and farsightedness. The last option of astigmatic keratotomy incisions corrects astigmatism where bulky regions of the cornea are reshaped with the help of a blade. It is suggested that one goes for LASIK or PRK instead of going for astigmatic keratotomy incision.
It must be noted that all surgeries involve a certain minimal risk and may have possible side effects. Consult an ophthalmologist before you go for any surgery.
