Everyone values the ability to see and will try their best to take care of their eyesight. However, despite their best efforts, people suffer from various eye diseases that cause them to wear corrective lenses and glasses. There are also eye problems such as hyperopia (farsightedness) and myopia (nearsightedness) that affect people of all ages. One way of treating such eye diseases is by using Laser-assisted in-situ keratomileusis (LASIK) surgery. Lasik is a refractive surgery that bends light rays to focus on the retina for sharper vision. Before patients undergo the LASIK surgery, it is important for them to know about some of the risks involved.
Before correcting vision problems with LASIK surgery, an eye surgeon will evaluate the thickness and shape of the cornea. People with irregularly-shaped or very thin corneas may not be the best candidates for this procedure. In some instances, Lasik eye surgery may involve the risk of undercorrections. These risks will occur if the eye surgeon removes very little tissue from the eye, meaning that the patient does not get the results they desired. Undercorrections mostly affect nearsighted people, and the best way to correct them is by using an enhancement (refractive) surgery.
Another common risk that patients with eye problems encounter is their vision going back to what is was before it was corrected. The problem mostly afflicts people with wounds that heal abnormally, pregnant women, and persons with hormonal imbalances.
A different risk of LASIK eye surgery is overcorrection. Such cases occur when surgeons remove a lot of tissue from the eyes of their patients. When compared to undercorrection, this problem is much more difficult for experts to rectify.
Patients who undergo LASIK eye surgery are also at risk of Astigmatism. This issue occurs when the tissue removal during surgery is uneven. A Singapore eye centre professional may recommend contact lenses, eyeglasses, or additional surgery to take care of the problem. Patients may also end up with visual changes or loss after the surgery as a result of several complications. Some patients also experience blurred vision, a condition that was absent before the surgery.
Night Vision Problems
After some people undergo the surgery, it becomes difficult for them to see at night. They may have double vision, halos whenever there are bright lights, and glares.
Drops in Tear production
After undergoing LASIK surgery, some people may experience reduced tear production. The problem is temporary and may last up to six months after the surgery. In such instances, the eyes may feel dry during the healing process. Dry eyes will reduce the ability to see clearly. A Singapore eye centre doctor may recommend the use of eye drops to deal with the temporary problem. If the problem is severe, patients can ask surgeons for the available corrective options. Among these is the placement of special plugs in the tear ducts that will also prevent the fluid from draining from the eyes.
Flap problems are other risks of LASIK eye surgery that can lead to complications such as inflammation, excessive secretion of tears, and infections. The problems occur when doctors remove or fold back the flaps during the surgery.
