Each eye is unique. Each eye condition is also unique.
Vision quality is largely determined by the size and shape of our eyes. With a healthy eye, light rays entering the eye are focused directly on the retina to form a sharp image, which is then sent to the brain via the optic nerve, resulting in a visual image. This results in a refractive error such as nearsightedness, farsightedness and astigmatism an irregular curvature of the cornea. Refractive errors are very widespread and affect people of all ages. Light rays are focused directly on the retina to create a clear image.
Refractive errors occur when the curvature of the cornea, the main determining factor of refractive power, is not aligned with the length of the eye.
As a result, the light rays are prevented from focusing directly on the retina. When the eyeball is too long, the light rays are focused in front of the retina. Distant objects appear blurry, those up close are clear.
Light rays are focused in front of the retina. When the eyeball is too short, the light rays are focused behind the retina.

Laser surgery involves the use of laser to change the shape and focus of the cornea to achieve perfect or near perfect vision. However, to be eligible for it, a patient should be over 18 years of age with stable eyesight for at least a year, and should not have a history of any significant eye condition such as glaucoma or ulcers, Dr Millicent Grim, specialist ophthalmologist and Laser specialist at the Gulf Eye Centre, Dubai, said.
There are other criteria as well to guarantee successful results. It is a decisive factor because less depth of tissue in the eye would make it difficult for surgical efficacy. Pregnant women, however, are not permitted to undergo the procedure until six weeks after delivery if they are not nursing. The pupil size, moistness of the eyes, and the thickness and curvature of the cornea are the main factors that are evaluated by the laser specialist to make the decision.
Depending on the tests, the ophthalmologist will be able to determine whether a patient needs the LASIK or surface laser procedure.

In LASIK, a thin flap is created on the cornea, corneal tissue removed and reshaped, which helps change the focus, and the flap closed, Dr Grim explained. In most cases, patients need only one laser procedure to achieve the desired results. However, 5 to 10 per cent of patients usually need another follow-up enhancement laser surgery three months later, Dr Grim said.
With over a 98 to per cent success rate, laser eye surgery has become one of the most common cosmetic surgeries with speedy and impressive results. Yet, there are many who remain wary of the risks. One of the common post-surgery risks of laser vision correction, if done when all conditions are not satisfactorily met, said Dr Grim, is low vision. Dr Pramod Warhekar, consultant ophthalmologist at Mediclinic City Hospital, pointed out that for many individuals over the age of 40, undergoing the procedure will not guarantee that they will not need glasses. According to Dr Warhekar, the mono-region approach is more common among women than men, as they are more self conscious about having to wear glasses.
