Understanding the Vision Conditions LASIK Can Treat

If you don’t have perfect vision, you’re not alone. In fact, only one in three American adults have 20/20 vision, and about 195 million Americans wear contact lenses or eyeglasses to correct their vision. Somehow, being in the majority isn’t all that comforting or fun when every day starts out with you searching for your eyeglasses or going through the cleaning and rinsing ritual for contact lenses.

And, the older you get, the more challenging the visual changes can become, especially if you wear eyeglasses. You may wear one pair of glasses to drive to work, then put on computer glasses during your work day, and then switch to readers at the end of the day as you wind down with a favorite book.

Do you wish you could ditch your glasses or contacts and just see clearly like people with perfect vision do? Thanks to LASIK® surgery, you may be able to do just that. In this blog, the highly skilled providers at the Tayani Institute explain what LASIK surgery is and the vision issues it can treat.

LASIK surgery explained

In order for you to see clearly, your cornea and lens must work together to bend — or refract — light so it focuses on the retina. The retina then receives this visual information and relays it to the optic nerve, which sends the image to your brain. Any issues along the way can create refractive errors, which can lead to blurry vision.

This is where LASIK surgery comes in. LASIK — which stands for “laser in situ keratomileusis — uses laser technology to change the shape of the cornea to allow light to bend correctly. Procedures are performed at the office and can permanently fix many common refractive errors.

The FDA approved LASIK surgery in 1999, and it has become one of the most popular elective surgeries in the United States. This is no doubt due to the fact 96-98% of LASIK patients end up with 20/20 vision.  

Vision issues LASIK surgery can treat

LASIK surgery can address many common refractive errors, such as astigmatism, farsightedness (hyperopia), and nearsightedness (myopia). 

Astigmatism

One of the most common refractive conditions LASIK surgery treats is astigmatism. Astigmatism results from an unequally round or misshapen cornea, which prevents light from bending properly to provide sharp images.

As a result of this physical anomaly, people with astigmatism experience blurry vision. Astigmatism is often associated with other refractive errors, such as nearsightedness and farsightedness, but it’s a separate condition.

Farsightedness

When people suffer from farsightedness, also called hyperopia, objects close up are blurry, and objects in the distance appear much clearer. Typically, farsightedness is hereditary, and you’re born with the condition. Sometimes this condition can get detected early through school eye tests or by noticing you can’t see the chalkboard clearly. 

Nearsightedness

The opposite issue is true for people with myopia or nearsightedness. In this case, your vision is clear up close, but objects in the distance appear blurry. LASIK surgery is particularly effective for mild and most moderate levels of nearsightedness. Like farsightedness, nearsightedness also tends to run in families. In some cases, it develops gradually, while in other cases, it can happen rapidly. It typically worsens in childhood and adolescence.  

If you’re ready to kick your glasses and contact lenses to the curb, schedule an in-depth LASIK consultation to find out if LASIK refractive surgery is right for you. To learn more, book an appointment online or over the phone with the Tayani Institute today.
