LASIK vs. Epi-LASIK

Advances in refractive surgery technology have resulted in a variety of options to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Two of the most common options available today are LASIK and Epi-LASIK. It is important to understand some of the differences in these procedures so that you choose the right one for your unique vision correction needs.

LASIK and Epi-LASIK are very similar procedures. Both use an excimer laser to reshape your cornea so that light focuses properly on your retina. However, there is a difference in the way each of these procedures access the underlying layers of corneal tissue. In Epi-LASIK, only the epithelium (the outermost layer of the cornea) is separated from the underlying corneal tissue. In LASIK, a thicker corneal flap is required to access the deeper layers of the cornea.

These varying techniques have several important implications for patients:

• LASIK generally results in a quicker recovery time; however, there is also a higher rate of flap complications
  
• Epi-LASIK will have a longer recovery time which requires special bandage contact lenses to be worn to promote proper healing; in general, it may take as long as six months to notice the full results of the procedure
  

The thickness of your cornea will generally determine whether you are a better candidate for LASIK or Epi-LASIK. In general, people with thin corneas may experience better results with Epi-LASIK. At your initial consultation, your ophthalmologist will conduct a thorough examination of your eyes to determine the ideal procedure for you.
