Nearsighted? Farsighted? Astigmatism? What Can LASIK Correct?

Many people hear about laser eye surgery and think, “Seeing without glasses? That sounds great! But can it fix my eyes?” The answer is that it depends. Not every condition that negatively impacts someone’s vision can be corrected by LASIK. For example, cataracts, macular degeneration and glaucoma cannot be corrected by LASIK and require a different procedure. The good news is that today we have more technology available than ever. Most people looking to improve their vision can be candidates for some kind of vision correction procedure these days.

So, what exactly does LASIK do?

When the cornea isn’t shaped properly to the eye, it causes light to not focus clearly. LASIK is a non-invasive eye surgery which uses a laser to reshape the cornea with a beam of cool light. Once LASIK has been performed, the light entering the eye can focus on the back of the retina properly which creates better vision. Prior to LASIK surgery, numerous tests will be performed to determine the condition of the eye and amount of correction needed.

Since there are many different things that could cause an eye to not be able to see clearly, what conditions can LASIK correct? The three main conditions with a cornea that LASIK can treat are:


1) NEARSIGHTEDNESS: Also called myopia, nearsightedness is an eye condition in which you can view objects up close clearly, but things farther away may appear blurry. Myopia occurs if the eyeball is too long or the cornea is too curved which causes the light entering the eye to not focus properly. People with myopia can have difficulty clearly seeing a TV screen from across the room, a whiteboard in school or while driving. This condition may be inherited, or developed depending on how a person uses their eyes. Those who spend considerable time reading, working at a computer, or doing intense close visual work are more likely to develop myopia. LASIK does an excellent job correcting nearsightedness.

 

2) FARSIGHTEDNESS: Also called hyperopia, farsightedness is the inability to see near objects as clearly as distant objects. Hyperopia occurs if the eyeball is too short or the cornea isn’t curved enough for the eye which causes the light entering the eye to not focus properly. Common signs of hyperopia include difficulty concentrating and maintaining a clear focus on near objects, eye strain, and fatigue. LASIK is a great option to correct this condition.

 

3) ASTIGMATISM: Astigmatism is a relatively common eye condition involving an irregular curvature of the cornea. Many people have some degree of astigmatism on top of nearsighted or farsightedness, even if it’s only minor. Physical irregularities in the cornea cause distortion of the viewed image on the retina. As a result, vision becomes blurred or doubled at any distance, and can lead to eye discomfort and headaches. Today, LASIK can correct astigmatism by reshaping the cornea as well.
