Scleral Contact Lenses
Although larger and more intimidating than Rigid Gas Permeable (RGP) contact lenses, Scleral contact lenses are significantly more comfortable. Instead of sitting on the cornea as RGP lenses do, these lenses actually rest on the sclera (the white of the eye, and hence their name) and vault over the cornea.
These lenses are the perfect marriage of the comfort of a soft contact lens, and the vision quality and acuity of an RGP.
Where Scleral contact lenses absolutely shine is with patients who have irregularities in their cornea, the most common of which is keratoconus. Because these lenses vault over top of the cornea, the fluid underneath the lens helps fill in the gaps because of any corneal irregularity to help regain lost potential of visual acuity.
We have had many keratoconus and post-corneal transplant patients achieve 20/20 or better visual acuity with these lenses when this was impossible with their standard glasses and contact lenses.
