Photorefractive Keratectomy (PRK)

Photorefractive Keratectomy (PRK)

Dr. Irwin Azman is a true expert when it comes to treating patients with Photorefractive Keratectomy surgery complications and problems.

The laser eye surgery intends to correct poor vision as well as astigmatisms by reshaping the cornea to enable light to focus onto the retina.

Despite the high volumes of successful  Photorefractive Keratectomy (PRK) procedures, many patients have long lasting side effects. While members in the eye care community all consider the procedure safe, these PRK side effects can occur if there are any underlying issues prior to the surgery

Patients often confuse Photorefractive Keratectomy with LASIK since they are both laser eye surgeries performed for visual enhancement. The primary difference between the two surgeries is the point on the cornea that the laser is used. During LASIK the flap on cornea is cut with a hand held blade, called a micro-keratome, or a laser then another laser is used to flatten the cornea. Photorefractive Keratectomy instead directs the laser onto the cornea in order to flatten it.

The outer layer of the cornea (the epithelium) is completely removed and discarded during Photorefractive Keratectomy. During this process, Bowman’s membrane is destroyed, completely ridding the smooth layer in the eye that is composed of collagen fibers, which ultimately hold the cornea in its perfectly round shape.

As a result, Dr. Azman works with countless patients who developed irregular corneas following their Photorefractive Keratectomy surgery.  These post PRK patients often complain of symptoms that include dry eyes, blurred vision, the inability to see well at night and even chronic pain.

Global Complex Eye Care specializes in abnormal corneas and has a variety of treatment options that restore the vision damaged by a misshaped cornea. One remedy, one such option can be a gas permeable scleral lens.

These large diameter contact lenses cover the cornea as well as the sclera (the white part of the eye) enabling patients with bulging corneas to wear them comfortably. Scleral lenses also have a special liquid that fills the space between the back surface of the lens and the front surface of the cornea. This liquid protects the compromised corneal tissue.

Other post-Photorefractive Keratectomy failure treatments may include eyeglasses, soft contact lenses, hybrid contact lenses, piggy-back contact lenses, CRT corneal reshaping therapy, corneal cross-linking, or intacs.
