Post Surgical Lenses
Special Reverse Geometry

This design is best suited for Post Lasik and Post RK corneas that show the flat, central ablation zone with steeper cornea curvature from the mid-periphery out. The standard lens diameter is 11.2 mm with a 9.0 mm back optic zone and a reverse secondary curve option.


Post Lasik: The topography at right shows the classic flat central zone created by ablating the cornea.
RK Corneas: Some of these corneas will have the flat central zone and others will not. If the topography shows the flat central area surrounded by a steeper peripheral area, use a reverse geometry lens. If it does NOT have the flat appearance in the center, use the standard Dyna Intra-Limbal lens design.
Post Penetrating Keratoplasty - Sunken Grafts: The graft area sinks resembling a Post Lasik topography. A reverse geometry option is needed.
