Keraring Procedure

In cases of progressive Keratoconus, or in those who are no longer able to wear contact lenses comfortably, an advanced treatment option available today is implantation of intra-corneal ring segments known as Kerarings.

This implant is composed of 1 to 2 semi circular segments made from a biocompatible material known as PMMA.  PMMA has a long history of safety and efficacy for intraocular implantation, having been used for over 50 years in the manufacture of intraocular lenses that are implanted during cataract surgery.

The Keraring procedure can achieve the following outcomes:

  • Flatten the cornea, reducing its cone-like shape
  • Regularise the corneal surface, reducing distortions and improving the quality of vision
  • Slow down progression of Keratoconus, stabilising the corneal shape and delaying or avoiding the need for corneal transplantation
  • Reduce myopia & astigmatism caused by Keratoconus, although there is no guarantee that glasses or contact lenses won’t be needed after the procedure
  • Improve the patient’s tolerance and comfort to contact lens wear

This treatment can be combined with topography-guided PTK and CXL to maximise the best possible outcome for each individual patient.
