2020 Vision | Facts About LASIK

Published on: 05/11/2020

Several people nowadays are considering laser refractive surgeries such as LASIK to gain back their 20/20 vision and here's why.

The daily struggle of putting in glasses and contact lenses simply doesn't work for everyone. Without a doubt, it is difficult to fully focus without 20/20 vision. 

Surgical procedures with the aim to improve the eye's focusing power are called refractive surgery. LASIK or laser in-situ keratomileusis is one of the most performed eye surgery to correct several vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. This surgical procedure works by reshaping the cornea to allow the light to travel through properly onto the retina.

The Benefits of LASIK

In general, the chance of getting a 20/25 vision or better is pretty high after refractive surgery. In a study published by All About Vision, it revealed that about 99% of patients achieved their desired vision after a LASIK surgery, and around 85% of patients are also satisfied with their near-perfect vision.

In most cases, you only must undergo LASIK once in your life as the improved vision you get after this surgery is expected to be permanent. However, people with a low grade of nearsightedness tend to have the most success with refractive surgery according to research. Results depend on your specific refractive error and other factors. 

Before, During, and After the Surgery

To ensure that LASIK will be safe for you, your eye doctor will perform a thorough eye exam. This method covers the evaluation of your cornea, pupil, refractive errors, and other eye conditions. If you used to wear contact lenses, you will need to completely stop using it for at least a few weeks before the surgery as it changes the shape of your cornea. 

Part of the doctor's assessment is to look for signs of eye infection, inflammation, high eye pressure, dry eyes, and large pupils. This is to determine whether you can undergo the procedure safely. During the LASIK, your eye will be positioned under the laser and an instrument called lid speculum that is used to keep your eyelids wide open.

Numbing eye drops will be applied to your eye to avoid discomfort during the procedure. The doctor will ask you to focus on a point of light as this will help you keep your eye fixed while the laser starts to reshape your cornea. The surgery is performed on each eye separately and usually takes 30 minutes or less to be completed. 

After the surgery, you will experience blurred vision, a slight itch on your eye, and a little pain, but you will recover your vision quickly as these post-surgery effects are normal at first. You will be asked to wear sunglasses during the day and an eye protector at night until your eye heals. You will be given post-surgery medications and the doctor will schedule you a follow-up appointment one to two days after the LASIK.

Who Benefits From LASIK?

Almost everyone can benefit from LASIK as it is bound to enhance a person’s life by significantly improving one’s vision. This eye correction surgery is mostly recommended to young professionals, mom and dads, and people who have an active lifestyle as it also defeats eye strain and fatigue while staying away from the hassle of visual problems.
