Advanced Surface Ablation
LASEK, PRK, and Epi-LASIK
Like LASIK and wavefront-guided custom cornea treatment, the Advanced Surface Ablation (PRK) procedure utilizes an excimer laser to reshape the cornea. It is used to correct nearsightedness, farsightedness, and astigmatism, and does not require the use of a microkeratome.
With Advanced Surface Ablation (PRK), the epithelium (or outer skin of the cornea) is removed and a laser is applied only to the front surface of the cornea. Once the laser treatment is performed, a soft contact lens is applied to the eye and left in place for several days. Advanced Surface Ablation (PRK) has a somewhat longer healing period than LASIK, and certain patients may experience slight discomfort after surgery.
