Renown scleral lens and topography innovator, exceptional contact lens specialist, popular lecturer and former GP Practitioner of the Year honoree Dr. Greg DeNaeyer provided a must see webinar on advanced scleral lens design applications. I always judge the quality of a GPLI webinar based on how excited I am at the conclusion – and the resulting sleep deprivation – and Dr. DeNaeyer’s was one of the best presentations we have ever had.
Some of the highlights included:
Residual cylinder correction: use of prism, toric and quadrant specifics haptics to assist in stability
Scleral lens multifocal candidates, design, fitting, and problem-solving
Wavefront correction benefits and software
Corneo-scleral topography: allowing for empirical design with very good alignment
Landing zone design: his research has found that 6% should have a spherical landing zone, 30% a toric, and 65% a quadrant-specific free-form design; the latter are necessary to prevent asymmetric edge lift or localized compression. When to use toric versus quadrant-specific designs is also discussed.
Custom scleral lens design for special cases including:
- Pinguecula
- Pterygium
- Conjunctival blebs
- Notched scleral lenses
Clinical cases accompanied all of the topics listed above
