Refractive Surgery Specific or RSS™ lenses feature a unique aberration control reverse geometry design which fits the unusually flat post-surgical central cornea. *Available with Reclaim multifocal optics.
The RSS Refractive Surgery Specific corneal GP lens has a unique reverse geometry design to ensure proper fitting of the unusually flat post-surgical central cornea. The lens provides proper clearance of the central cornea without excessive vaulting, while allowing mid-peripheral alignment, and providing good centration and stable vision. Each fitting curve offers a broad range of central base curves to fit all eyes and a choice of three (3) peripheral edge configurations (standard, flat, steep) optimizing tear exchange and comfort.
The aspheric central base curve coupled with unique reverse geometry provides good centration and stable vision. The design is indicated for patients who have undergone refractive surgery procedures such as Radial Keratotomy (RK) or LASIK. It may also be used for patients who have undergone penetrating keratoplasty with the result of a central cornea that is flatter than the peripheral cornea. The RSS is easy to fit from topography or keratometry readings or can be fit using diagnostic lenses if so desired. The lens provides correction of refractive errors and irregular astigmatism and is very predictable.
The lens is available in any GP material, has a standard diameter of 10.5 mm, but is available in diameters that range from 9.5 mm to 12.0 mm. The parameters include FITTING CURVES that range between 39.00D to 46.00D in 1.00D increments, CENTRAL BASE CURVES are available 1.00D to 9.00D flatter than the FITTING CURVE in 0.50D increments and powers from +20.00D to -20.00D.
