What Conditions Does LASIK Eye Surgery Correct?

Many people experience visual errors which necessitate the need for corrective eyewear like glasses and contact lenses periodically or all the time. The highly effective LASIK eye surgery can reduce or sometimes eliminate dependence on such eyewear. Furthermore, the procedure has an impressive 96 percent success rate, according to the Journal of Cataract & Refractive Surgery. 

But what does LASIK eye surgery correct in terms of specific visual errors? As an ophthalmologist of more than 20 years, Dr. Laurence Sperber of New York, NY, regularly recommends and performs LASIK to correct nearsightedness, farsightedness, astigmatism, presbyopia, and a number of higher order aberrations.

LASIK is an especially popular option for patients whose vision suffering from presbyopia as they get older. 

LASIK for Nearsighted Patients

Patients who suffer from myopia, more commonly referred to as nearsightedness, cannot clearly see items at a distance. This makes driving, watching television, and even walking safely from point to point difficult or potentially dangerous.

LASIK eye surgery allows Dr. Sperber to change the shape of a nearsighted patient’s cornea by removing microscopic amounts of tissue. As a consequence, 99 percent of patients can expect at least 20/40 vision after their eyes have fully healed and a full 90 percent of patients report their eyesight at 20/20 post-LASIK.

LASIK for Farsighted Patients

Hyperopia, commonly called farsightedness, is essentially the opposite of myopia and is caused by a cornea that is too flat. Rather than having difficulty seeing objects far away, patients with hyperopia cannot clearly see objects that are close to their eyes. Even reading an email on a tablet or smartphone can be challenging without corrective glasses or contact lenses.

Patients...with farsightedness are likely to see improvements of at least 20/40 vision.

By creating more of a curve in the cornea during LASIK eye surgery, Dr. Sperber can correct farsightedness. Like patients with nearsightedness, those with farsightedness who are excellent candidates are likely to see improvements of at least 20/40 vision.

LASIK for Patients With Astigmatism

Astigmatism, a condition that causes the cornea to be irregularly shaped, can occur in people with myopia or hyperopia. The LASIK treatment reshapes the cornea to bring the patient’s vision as close to 20/20 as possible.

LASIK for Patients With Presbyopia

Presbyopia, a type of farsightedness that commonly develops as we age, can also be corrected with LASIK. However, the correction protocol for patients with presbyopia is to use the LASIK process to make one eye more nearsighted and the other eye equally farsighted. When the eyes work together, they naturally overcome presbyopic issues.

LASIK for Patients with Higher Order Aberrations

Where lower order aberrations like nearsightedness, farsightedness, and astigmatisms affect the cornea, higher order aberrations are imperfections of any refractive part of the eye, including the cornea, lens, and tears. These can lead to halos, double vision, and poor night vision. With advancements in custom wavefront LASIK technology, these aberrations are now treatable, as well. 

Can Your Visual Error Be Corrected With LASIK?

If you know or think you have any of the aforementioned conditions, you may be a candidate for LASIK. However, you cannot be certain without a more thorough, personalized examination. After all, other pre-existing conditions and concerns such as glaucoma, cataracts, and overall patient health have to be taken into consideration when evaluating a patient for LASIK.
