The Science and Art of Scleral Lenses
   
   

Until now, all scleral RGP lenses were fit using trial lenses. The final fit was only as good as the number of trial lenses available, the time available to both patient and practitioner, plus the expertise and skill of the practitioner. Scanning technology is now available to measure the cornea out to the sclera where edge design is critical. Global Refractive Solutions has pioneered in designing one-of-a-kind lenses for the ideal fit on any eye -- surgical or non-surgical.

 
Presription change after LASIK surgery Mini-scleral lens in place corrects refraction on LASIK surgery patient  
  This 3D image represents how the prescription changes across the pupil in an eye that had LASIK surgery. Note how the prescription varies from about +1.00 to -7.00, an 8 diopter spread across the pupil.

The same eye with a GRS-designed mini-scleral lens in place, resulting in a uniform refraction or power across the entire pupil.

  Computer generated image of how this post-LASIK patient might see a point light source in the dark based upon wavefront aberrometry.

The same eye measured with a GRS-designed mini-scleral lens on the eye. The lens restores higher order aberrations to normal levels resulting in a point source appearing as a point source.
