Radial Keratotomy Lens Treatment

Radial keratotomy was a treatment popular in the 1980s and 1990s that used a blade to cut incisions with the intention to correct myopia and astigmatism. While there may have been initial success, many have regressed and have become far-sighted. On top of this, there are many other
RK Txcomplications that have occurred:

  • permanent decrease in visual acuity
  • double vision
  • glare/halo
  • dry eye
  • irregular astigmatism

Fortunately, many of these complications can be improved with advancements in optometric technology. Some doctors may suggest additional surgery to smooth the cornea, like LASIK, but I believe additional elective surgery to an already compromised and weakened cornea may not be the most beneficial. A less invasive technique is preferred in my opinion: a gas permeable scleral contact lenses. I believe this modality is the best modality because of the therapeutic benefits and an increase in visual potential. Some of these therapeutic benefits include:

  • dry eye relief
  • irritation relief
  • non-fluctuating and stable vision
  • astigmatism correction

These benefits are achieved by the mechanism of a scleral lens. Since the lens is filled with saline, this saline will provide a smooth optical media for light to travel through to provide better vision thereby potentially eliminating blur, halo, glare, double vision, etc. Moreover, this interface also interacts with the cornea to provide a therapeutic environment. It is in my experience that a scleral lens will provide increased comfort and improved vision without the need for additional surgeries.
