PRK

Serving Oklahoma City, Norman, Edmond & nearby areas of Oklahoma

At Hummel Eye Associates in Oklahoma City, PRK (Photorefractive Keratectomy ) has been available for many years. Since the FDA approval of LASIK, most surgeons recommend that procedure over PRK. If you have been told that you’re not a good candidate for LASIK, you might still be a candidate for PRK. It’s an older procedure than LASIK and no corneal flap is created.

PRK is an option if you have:

  • Thin corneas
  • Large pupils
  • Recurrent corneal erosion
  • Corneal scars
  • Corneal dystrophy

PRK can correct low to moderate nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. We first create a 3-D map of each cornea. The two maps show in microscopic detail all the exact contours of your eyes. Using this data and his own skill, Dr. Hummel devises your treatment plan and based on this plan, the computer will guide the laser during surgery.

Contact lens patients will be asked to stop wearing lenses for a period of time before your eyes are measured and mapped. Contact lenses alter the shape of the cornea and we must get an accurate reading in order to make the correct adjustments. The length of time you must go without your contacts will depend on what type you wear.

The Procedure
Like LASIK, PRK does not require general anesthesia. We will give you an oral sedative to help you relax, and anesthetic eye drops to prevent discomfort.

  • Dr. Hummel will use an instrument to hold your eyelids open so that you do not blink.
  •  Dr. Hummel will remove a very thin layer of surface cells from the cornea. This gives him access to the second corneal layer, the stroma, where the reshaping occurs
  • A cool beam laser, called the VISX Excimer laser, is used to reshape the stroma by vaporizing pre-determined tiny pieces of tissue.
  • A bandage contact lens is placed on the eye and you will be given anti-inflammatory and antibiotic eye drops.

The procedure itself only takes a few minutes, but you should plan to spend a couple of hours in our Laser Center. You can leave shortly after your surgery, but you will need to have someone drive you home. In most cases, only one eye is treated at a time.

Recovery
The bandage contact is removed about two or three days after surgery, when the surface epithelium has regrown. You will have multiple follow-up visits, usually one day, three days, one week, one month, three months, and six months after the procedure.

The final results are similar to those of LASIK, but your vision may be blurry for the first few days after surgery, and it can be several months before you enjoy the full results.

The big advantage of PRK is that if you have extra thin corneas, and therefore can’t have LASIK, you can still have vision correction. That’s because no flap is created. The amount of corneal tissue removed in PRK is less than a flap requires. If you have questions, please Contact us to set up an initial consultation.
