Check out my article in GP Insights on scleral lens fenestrations.
The Scleral Lens Education Society, in partnership with B+L, has put together a comprehensive video on the application/removal and care of scleral lenses.
Improvements in specialty lens designs have made this contact lens modality a viable option for patients who have mild to moderate keratoconus. Generally, these soft lenses have center thickness 4X greater than standard soft lenses, which allows them to mask surface irregularity caused by keratoconus. When necessary, they can be manufactured using silicone hydrogel material that increase oxygen to the corneal surface. Specialty soft lenses for keratoconus can be a successful alternative when standard GP designs fail secondary to comfort issues.
The 2012 Global Specialty Lens Symposium was held in Las Vegas from January 26-29th. Over 450 contact lens practitioners from all over the world participated in this year’s meeting, and scleral lenses were a popular topic. I was honored to have been selected to present two lectures, one of which included information about managing post-operative corneal irregularity with scleral lenses.
Scleral Lenses can range in diameter from 12.5mm to 25mm. I generally use scleral lenses that are 18mm for most cases of corneal irregularity or ocular surface disease.
