Manual of Gas Permeable Contact Lenses by Edward S. Bennett OD MSEd, Milton M. Hom OD FAAO

By Edward S. Bennett OD MSEd, Milton M. Hom OD FAAO

Curiosity in prescribing inflexible fuel permeable (RGP) touch lenses is at the upward thrust, fueled by way of the elevated use of orthkeratology, bifocal lenses, and advances in corneal topography (making becoming easier). This concise and entire source presents necessary insurance for the prescribing and becoming of RGP lenses. in accordance with the authors' years of craftsmanship in becoming those lenses, this clinically orientated handbook additionally contains a spouse CD-ROM to demonstrate the appropriate techniques.

  • Content focuses in particular on inflexible gasoline permeable touch lenses so all of the crucial details wanted for prescribing and becoming is in a single, handy resource.
  • A significant other CD-ROM illustrates the tough becoming thoughts encountered with RGPs.

Today’s materials possess cross-linkers to enhance rigidity, while providing higher Dk values. However, one study has shown that the advantage of crosslinkers may not translate into measurable clinical benefits. 26 Do the new materials offer better flexure resistance? Although these newer generation materials may still flex on the eye, the problem is considered greatly reduced than during the days of Polycon. 27 However, the answer may not be that simple. Another study has shown that there is no correlation between permeability and flexure measured with autokeratometry.
