LASIK, which stands for laser-assisted in situ keratomileusis, also commonly referred to as laser eye surgery or laser vision correction, is the most popular form of refractive surgery for the correction of myopia, hyperopia and astigmatism.
For clear vision, the eye’s cornea and lens must bend (refract) light rays properly. This allows images to be focused on the retina. Otherwise, the images will be blurry. This blurriness is referred to as a refractive error and is caused by a difference between the shape or curvature of the cornea and the length of the eye.
In Buffalo, Dr. Atwal performs LASIK surgery by using a laser to reshape the eye’s cornea, improving visual acuity. For many patients LASIK provides a permanent alternative to eyeglasses or contact lenses.
During the LASIK procedure a flap of corneal tissue is created. This flap is then peeled back so that the laser can reshape the corneal tissue underneath. Once the reshaping is complete, Dr. Atwal replaces the flap. The cornea will naturally hold the flap in place, so no stitches are required.
Although LASIK has helped millions of people improve their vision and reduce their need for glasses or contacts, not everyone is a good candidate for the procedure. You must be at least 18 years old, have healthy eyes and a stable prescription that is within the range that LASIK can correct. It’s also important to consider the risks and rewards and make sure you have realistic expectations.
Potential LASIK risks may include:
- Corneal infection
- Corneal scarring or permanent problems with the cornea’s shape, making it impossible to wear contact lenses
- Decrease in contrast sensitivity, even with 20/20 vision, objects may appear fuzzy or gray
- Dry eyes
- Glare or halos
- Light sensitivity
- Night driving problems
- Reduced vision or permanent vision loss
