GVR Scleral Lens over Extremely Thin (120 Microns) Keratoconic Cornea

This image shows a scleral lens over a extremely thin (120 microns thick) keratoconic cornea. While this eye never underwent LASIK or any other type of surgery, the purpose is to show how a well fit scleral lens can safely vault over a thinned out cornea. The top 2 lines represent the front and back surfaces of the scleral lens. The thinned out grey structure is the cornea. This patient has been able to successfully wear her scleral lens for the past 3 years. I have never seen a cornea perforated by a scleral lens.
