Custom PRK

What is PRK?

PRK (Photorefractive Keratectomy) is a laser refractive procedure to correct nearsightedness, farsightedness and astigmatism. PRK is a surface ablation procedure similar to LASIK. It involves removing the outer layer of the cornea (the epithelium) and re-sculpting the cornea with the excimer laser. Custom laser treatment is available with PRK . After the laser application, the surgeon places a soft bandage contact lens on the eye to allow the epithelium to heal over the operated area.

PRK has been performed since 1980’s and prior to LASIK, it was the most commonly performed laser vision correction procedure. PRK is similar to LASIK and uses the excimer laser to reshape the front surface of the cornea, but unlike LASIK there is no flap created during the procedure. This procedure is generally recommended for patients with thinner corneas, mild irregularities of the corneal surface, and patients with mild ocular dryness because it is less disruptive to the corneal nerves.

After the Procedure

After PRK, patients may feel some discomfort and experience slightly blurred vision for approximately 4 days as the epithelium heals. Patients are instructed to use steroid eye drops over several weeks, requiring frequent follow-ups with their eye doctor. Shortly after the bandage contact lens is removed normal activities can be resumed, although it can take a several weeks for optimal vision to stabilize.
