Debunking Myths About LASIK Surgery
LASIK, or laser-assisted in situ keratomileusis, is a refractive surgery that corrects vision problems such as nearsightedness, farsightedness, and astigmatism. This procedure uses a specialized laser to reshape the cornea, which is the clear front part of the eye, enabling light entering the eye to be properly focused onto the retina. The goal of this procedure is to reduce or eliminate their dependence on glasses or contact lenses. LASIK surgery is common, but misconceptions about it persist. Here’s information debunking myths about LASIK surgery:
Myth 1: Anyone Can Get LASIK
A common misconception is that anyone who wears glasses is automatically eligible for laser vision correction, but this is not true. Ideal candidates for LASIK surgery are individuals over 18 years old who have had a stable vision prescription for at least one year. Doctors perform thorough screenings, assessing if you qualify for a safe and effective surgery.
Who Is a Good Candidate?
Doctors look for healthy corneas with sufficient thickness to withstand the reshaping process. Certain conditions may disqualify an individual, including severe dry eye syndrome, thin corneas, or autoimmune diseases that affect healing. Women who are pregnant or nursing are usually advised to wait, as hormonal changes can temporarily alter vision prescriptions.
What Is Surgery Like?
The entire process takes less than 30 minutes for both eyes, and LASIK surgery begins with the creation of a thin flap on the cornea’s surface using lasers. The surgeon lifts this flap to access the underlying corneal tissue. A laser then removes microscopic amounts of tissue to reshape the corneal curvature according to each person’s prescription. Once the reshaping is complete, the surgeon repositions the flap, where it adheres naturally without stitches.
Myth 2: LASIK Results Are Always Permanent
Many people assume that once they undergo LASIK, their vision will remain perfect for the rest of their lives. The reshaping of the cornea is permanent, but the eye itself is a living organ that changes over time. Natural aging processes still affect the eyes regardless of previous surgeries.
Almost everyone develops presbyopia around the age of 40, a condition where the lens of the eye loses flexibility, making it difficult to focus on close objects. This means someone who had LASIK in their 20s may still need reading glasses later in life. Some individuals may experience regression, where the eye slightly returns toward its original prescription, though this is less common. In these instances, an enhancement procedure might be an option to fine-tune the vision.
Myth 3: LASIK Is Painful
Fear of pain is an understandable barrier for many people concerning surgical procedures, but LASIK surgery doesn’t cause pain. This is because the surgeon applies numbing eye drops to completely anesthetize the surface of the eye beforehand. During the procedure, you may feel a brief sensation of pressure on the eye, particularly when the corneal flap is created. After the anesthesia wears off, it is common to experience some discomfort, often described as a gritty sensation or mild burning, similar to having an eyelash in the eye. Your eyes are healing, but these symptoms should stop on their own after a week.
