Correcting Radial Keratotomy (RK) Complications

Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness) that was developed in 1974. It has been superseded by newer operations, such as photorefractive keratectomy (PRK), LASIK, Intra-Lasik, Wavefront Lasik, and others. Although rarely done now, millions of people underwent RK in the 80’s and 90’s around the world with over a million procedures done in the United States. In addition, many of these RK patients had LASIK in an attempt to undo damage caused by their initial RK surgery.

With the RK procedure, incisions are made on the cornea with a scalpel (knife). These tiny cuts flatten the surface of the cornea and reduce nearsightedness. The surgeon may make additional cuts to flatten the misshapen part of the cornea for those people who have both astigmatism and nearsightedness. The long term results of radial keratotomy (RK) complications have truly been horrific for many people. Numerous problems occurred years later. These include:

• Loss of Best Corrected Visual Acuity
• Severe Dry Eye
• Unstable or Fluctuating Vision
• Double or Triple Vision
• Irregular Astigmatism
• Halos, Glare, and Reduced Night Vision

Many RK patients also underwent additional RK procedures followed by one or more LASIK procedures. In every instance, the additional procedures only exacerbated the problem. In recent years, advances in specialty lenses including Scleral lenses and other unique advanced lens technologies have become available which will allow patients to see clearly and comfortably once again, without the risk of further surgery.

The images below show how one of our patients, Sharon B., sees at night after having RK surgery vs. how she now sees with a Scleral lens.

Times Have Changed – Technological Advances at Global Complex Eye Care 

Contact lenses are not what they used to be… even two years ago. Technological advances have greatly improved contact lenses and lens care products – revolutionizing vision correction.

Scleral Contact Lens
Scleral contacts are large-diameter gas permeable contact lenses specially designed to vault over the entire corneal surface and rest on the “white” of the eye (sclera). In doing so, scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by Keratoconus, Lasik failures, post-surgical complications, and other corneal irregularities.

Because scleral lenses are designed to vault the corneal surface and rest on the less sensitive surface of the sclera, these lenses often are more comfortable for a person with corneal irregularities. A special liquid fills the space between the back surface of the lens and the front surface of the cornea. This liquid acts as a buffer and protects the compromised corneal tissue. Scleral lenses are designed to fit with little or no lens movement during blinks, making them more stable on the eye, compared with traditional corneal gas permeable lenses. These lenses are almost always very comfortable and the vision provided by them is extremely good. The great majority of patients are able to wear their scleral lenses almost all of their waking hours without problems.

Dr. Irwin Azman prescribes scleral contact lenses for a variety of hard-to-fit eyes, including patients with Stevens-Johnson Syndrome, Radial Keratotomy and Lasik Complications and failures, Keratoconus, Corneal Ectasia, Post-Surgical Vision Loss, and Pellucid Marginal Degeneration.
