More than 60 percent of adults wear glasses. Since the invention of laser surgery at Columbia University in the 1970s, contact lens and eyeglass wearers dreamed of the day they could throw away their eyeglasses and contact lenses.
As the lasik surgery is more perfected through the years, many people are taking advantage of this miracle surgery. In lasik surgery, a flap is cut in the eye. A laser beam is flashed in the flap to reshape the cornea, correcting the nearsighted or farsighted problem. Then,the flap is replaced. There’s a downside. While most people tend to have no problems with the surgery, the problems with the surgery depend on whether the flap was cut too thin or too thick.
Unfortunately, even if the laser surgery is successful, about 50 percent of people who have the surgery performed will need to wear glasses in a couple of years. Once the flap is cut, there’s a chance that it could open again. http://www.tvshowupdate.com/dr-oz-lasik-eye-surgery-work-complications-long-last/
Lasik surgery is created to treat people who are nearsighted, farsighted, and have astigmatism. Like any other surgery, there are many risk factors. During the first few months following laser surgery, patients have reported such eye problems as extra light sensitivity, dry eye, reduction in vision sharpness, glare and halos in their vision, and vision sharpness is reduced. On the plus side, these are temporary effects that heal within 3-6 months. http://www.allaboutvision.com/visionsurgery.
Just 15 years after Mel B of the Spice Girls had laser surgery, she was blinded in her left eye. Usually, recovery takes more than a year. Today, lasers can remove corneal tissue and badly effect vision quality permanently. There are going to be some other examples. http://lasikcomplications.com/
There are eye diseases that include post LASIK extarsia and eye infections. Post LASIK extarsia is when the cornea bulges, causing blurred vision. Eye infections are another of the eye diseases that can happen. This is when the eye becomes red and starts oozing. Striae is when flap that was created during the surgery causes wrinkles on the cornea, distorting vision.
Other eye problems include irregular astigmatism and Epithelia ingrowth. Astigmatism is a slight curvature of the cornea. Usually, this makes it difficult for people to wear contact lenses. Irregular astigmatism is when people see double vision or ghosting. This isn’t correctable with glasses or special contact lenses.
Epithelia ingrowth is another eye problem that can happen with laser surgery. The epithelium is located under the tear film of the eye. In laser surgery when cells begin to grow under the cornea flap, then bumps can occur. When bumps develop on the cornea flap, this is called epithelial ingrowth. Most of the time, these cells will die and be absorbed into the cornea, creating no problems. Sometimes these epithelial cells will remain on the cornea flap and steal nutrients away from the cornea. http://www.usaeyes.org/lasik/faq/epithelial-ingrowth.htm
If a person really wants to have laser surgery, he or she should consult a good physician and get a referral with an ophthalmologist. This is easily achieved if you are living in Singapore. You can get such service from a good Singapore eye centre which operates under strict guidelines by Singapore’s Ministry of Health.
