Advanced Surface Ablation (ASA) Laser Eye Surgery

ASA or “advanced surface ablation” is an advanced form of PRK, or “photorefractive keratectomy,” the predecessor to LASIK eye surgery. It is a type of vision correction surgery to treat nearsightedness (myopia), farsightedness (hyperopia), astigmatism or presbyopia. If you already have glasses, laser eye surgery can be life-changing. PRK surgery reshapes the cornea for vision clarity. Dr. George Waring and his professional staff at the Waring Vision Institute have been involved in the development of modern vision correction treatments, and the clinic is a premier destination for advanced vision correction.

What to Expect During
ASA Laser Surgery

You may need to undergo the ASA procedure if you are not a candidate for LASIK, and have thinning corneas, corneal scarring or have a profession that is considered “high contact.” Your prescription for glasses or contacts should be stable for approximately 12 months before undergoing laser vision correction.

In ASA surgery the epithelium, or the outer layer of the cornea, is gently removed. The surgeon will then use a special excimer (a specialized ultraviolet laser) to reshape the cornea. The treatment will fine-tune and fix small imperfections in the curvature of the cornea. The laser is extremely accurate and the procedure very quick. The surgery only takes about 10 minutes per eye and is relatively painless. The portion of the epithelium that was removed will grow back on its own within a few days while you wear a special bandage contact lens. A LASIK flap is not required in ASA, therefore, many people who were not candidates for LASIK may benefit from ASA.

Recovery
After PRK

After the surgery is complete you will be evaluated briefly. Once you are cleared to leave, you will need to be driven home by a family member or friend. Some common side effects of the procedure are:

  • Mild pain or discomfort
  • Sensitivity to light
  • Glare or halos around objects or lights
  • Dry eyes
  • Difficulty seeing at night

Side effects are usually mild and can be managed with medication. It’s vital to the healing process to follow all aftercare instructions. Most clients can drive a vehicle within one to three weeks after surgery, but it can take up to a few months to restore clear and stable vision. The results of PRK surgery are remarkable. Most clients greatly reduce or even eliminate their need for glasses or contacts, and in some cases people enjoy better than 20/20 vision.
