Correct Your Impaired Vision through PRK Surgery
PRK surgery is an established, effective surgery offered at our Northglenn, CO, practice to correct impaired vision. At Montgomery Eye Care, this procedure is often recommended as an alternative treatment for patients who do not qualify for LASIK. It involves the removal of the epithelium and reshaping of the underlying cornea with a high caliber excimer laser to treat nearsightedness, farsightedness, and astigmatism. Dr. Montgomery and his team provide quality care, advanced technology, and superb customer service with a no-pressure approach for each patient that walks through our door.
What Is PRK Surgery?
PRK surgery (photorefractive keratectomy) was the first laser eye surgery performed to reshape the cornea and correct minor to moderately impaired vision. This procedure is often recommended when patients do not qualify for LASIK eye surgery, due to thin corneas and large pupils.
When the cornea, the thin outermost layer of the eye, is misshaped, it prevents the retina from processing images properly, leading to distorted vision, blurriness, and trouble focusing. During PRK surgery, Dr. Montgomery uses an excimer laser to remove the epithelium and reshape the corneal tissue to help the cornea refract light properly and improve vision. The overall procedure takes less than 15 minutes and produces long-lasting results.
Determining Your Candidacy
PRK is often recommended for patients with thin corneas, large pupils, or patients who are unable to undergo a subsequent LASIK surgery. During your initial consultation, Dr. Montgomery will perform a thorough eye exam and a series of tests to ensure that you are an ideal candidate for this procedure.
Due to the nature of this surgery, it is imperative that you have no signs of glaucoma or other eye abnormalities. In addition to a desire to be free of glasses and contact lenses, in order to qualify for PRK you must also:
- Be in good overall health
- Be over the age of 18
- Have stable vision
- Not have an autoimmune disease
- Not have diabetes or arthritis
- Not be pregnant or nursing
Once candidacy has been determined, Dr. Montgomery will review preoperative and postoperative instructions with you to ensure you have a smooth recovery and optimal results.
How Is PRK Performed?
You will need to have someone drive you to and from the procedure. Before beginning the procedure, Dr. Montgomery will numb your eyes with local anesthetic eye drops and place a speculum over the eye to prevent blinking.
A map of your eye will be programmed into the computer, which allows the laser to deliver precise and accurate results.
Dr. Montgomery will gently remove the epithelial layer of the cornea with the bladeless wavefront Ziemer LDV femtosecond laser and then carefully reshape the cornea with the Alcon WaveLight® EX500. These excimer lasers are extremely safe and efficient. A map of your eye will be programmed into the computer, which allows the laser to deliver precise and accurate results.
