LASIK vs. LESA™: What’s the Difference?

LASIK vs. LESA™: What’s the Difference?

If you wear glasses or contact lenses, there may be times when you wish you could take them off and toss them aside for good. You’d love to go corrective lens-free, but, like most people, you couldn’t function well for more than a few minutes without your lenses!

The good news is that you have alternatives to eyeglasses and contacts. The eye care specialists at Advanced Laser & Eye Center of Arizona, home of MyEyesToday.com, offer innovative vision correction surgeries, including LASIK and LESA™, so you can say goodbye to regular corrective lens use.

LASIK and LESA are similar in some ways, but they also have some important differences. Here, our providers explain some of the variations between LASIK and LESA.

LASIK: State-of-the-art laser surgery

LASIK stands for “laser in situ keratomileusis.” It’s an outpatient procedure that uses laser energy to adjust the shape of your cornea, which plays an important role in your vision.

The cornea is the transparent, dome-shaped layer located at the front of your eye. When you look at something, light passes through your cornea, which bends and focuses the light. When the light hits your retina in the back of your eye, the light is converted into electrical signals that travel to your brain.

When the shape of your cornea changes, it doesn’t bend and focus light properly. As a result, you may experience vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

LASIK uses an advanced laser to reshape your cornea and improve your vision. It’s a safe, effective, minimally invasive outpatient procedure that may reduce or eliminate your need for contact lenses and eyeglasses.

LASIK has some limitations. For example, we don’t recommend it for presbyopia, which is the age-related eye condition that necessitates reading glasses. In addition, LASIK may not eliminate the need for eyeglasses or contacts in people with very weak vision. 

Patients who receive LASIK may require touch-up procedures in the future so they can continue to see well without glasses or contacts.

LESA: A change of lenses

LESA stands for “lens of the eye surgical alteration.” LESA is what’s known as an intraocular lens exchange procedure, which replaces your eye’s lens with a new, artificial lens. Like your corneas, your eyes’ lenses help bend and focus the light as it enters your eye and travels to your retina. 

LESA is a minimally invasive outpatient procedure that can improve your vision. It offers some advantages that LASIK does not.

For example, LESA can usually restore your ability to see up close and far away. What’s more, it’s less likely than LASIK to cause dry eyes. And it’s more likely than LASIK to eliminate the need for reading glasses in older patients.

Our practice is the first in the nation to offer and promote the LESA. For many patients, LESA offers permanent vision correction that lasts the rest of their life.
