Step 2 - The Protective Flap
LASIK's main advantage is in reshaping the corneal tissue (stroma) from the inside. This preserves the cornea's sensitive top layer of cells. Formerly PRK reshaped the cornea by removing the actual surface tissue of the cornea.
- Dr. Ashraf at the Atlanta Vision Clinic first will completely numb your eye using an "eye drop" anesthesia.
- Next an eyelid holder will be placed over your eye to help prevent you from blinking.
- Lastly, an instrument called a microkeratome creates the protective corneal flap. While you may feel a little pressure you will feel no discomfort.
