Every pair of eyes is unique and that is why there are various LASIK alternatives to help every person gain visual freedom - crisp, clear vision with less dependence on glasses and contact lenses.

Patients who are nearsighted, farsighted, or have astigmatism could benefit from this procedure.

PRK is commonly known as "LASIK without the flap." The procedure treats the surface of your eye without a flap via a microscopic opening on the cornea (as is done in LASIK). Then, the laser treatment in PRK gently scrubs the surface of the cornea, eliminating all potential complications of a LASIK flap.

Who benefits most from PRK?

PRK may be used if your eye surgeon finds that you have thinner-than-average corneas, and there is not enough corneal thickness for a LASIK flap. Soft corneas have a greater chance of bending out of shape and are also not suitable for the creation of a corneal flap. Therefore, PRK is the alternative. Despite the slight discomfort of PRK compared to LASIK, Dr. Greenberg may recommend PRK over LASIK based on the results of your comprehensive eye examination. Our specialists will discuss which procedure better suits your visual needs during your consultation.


What are the results of PRK compared to LASIK?

The visual outcome is the same whether LASIK or PRK vision correction is performed. Both procedures are also equally safe—the main differences are the time it takes to heal and frequency of post-surgery visits.


What is the recovery time for PRK?

For patients receiving PRK, it may be several days before you feel comfortable returning to work and normal activity. Pain is usually quite minimal after surgery, although postoperative discomfort is a possibility.
