Correcting Myopia with LASIK

Diagram of a normal eye

Myopia is a refractive defect of the eye. It can be described as the condition in which the eyeball is elongated. It prevents light rays to focus on retina and the image is focused in front of the retina, forming a blurred image. Myopia or nearsightedness affects a large number of people. People commonly rely on glasses and contact lens to correct the problem.

Nowadays, however, more people are opting for LASIK surgery for myopia, because it’s safe and effective. With LASIK eye surgery, people who suffer from myopia would be free from their glasses and contact lens. Many sportspersons and people in the entertainment industry go for LASIK to correct their nearsightedness. LASIK is a short procedure that takes not more than 10 to 15 minutes and the patient can see clearly in just a few days. There’s no requirement to stay in the hospital after the surgery and the complete process takes less than two hours. Let’s look at laser eye surgery for myopia in more detail.


How It Affects the Body?

People suffering from myopia cannot see objects clearly at a distance. The condition is prevalent among school going children, but the condition typically stabilizes after the age of 20 years old. There are different types of myopia such as axial myopia and refractive myopia. People who have a high glucose level may also suffer from myopia caused by the swelling of lens and accumulation of sugar alcohol in the lens.

Myopia can happen due to environmental factors, close viewing of TV and computer screen, reading in dimly lit places or poor exposure to sunlight during infancy. People can suffer from induced myopia due to the exposure to certain drugs, increased level of glucose, toxins, exposure to chemicals, and even the use of encircling bands which are used for retinal detachment.

What Can Happen if it is Left Untreated?

Some of the myopia symptoms include headaches, eyestrains, and fatigue, especially when the patient has to drive, work or play. Untreated myopia can result in glaucoma and night blindness. 

What Is Lasik Is And How It Can Be Used To Correct Myopia?

People suffering from myopia generally require myopic correction for less than 10 dioptre, which is an ideal condition for LASIK surgery. The cornea which is the main part of the eye contains epithelium, stroma, and endothelium layers. During the surgery, lasers are used to modify the curvature of stroma and reshape the cornea. Argon-Fluoride excimer laser can be used to correct refractive error. The main benefit of LASIK eye surgery is that it can cure eye defects without the need for stitches because the laser beams can reach deep tissues to provide the desired changes.

Most people who suffer from myopia find LASIK very effective and LASIK is the best option for those whose vision has stabilized and still needs improvement. People who are above the age of 40 years should be
careful before going for the surgery, as they maybe a higher risk of complications. LASIK is safe for people who suffer from stable myopia with the suitable corneal thickness needed for the surgery. However, LASIK eye surgery is not recommended for pregnant women.
