A novel large diameter rigid gas-permeable corneal contact lens design for keratoconus. [PDF]
J OptomTo assess the fitting process and clinical feasibility of a novel large diameter rigid gas-permeable (RGP) corneal contact lens (CL) presenting regular or reverse geometry for managing keratoconus (KC). The lens was designed to rest on the peripheral cornea and vault over the cone, aiming to enhance visual quality, comfort, and corneal physiology.32 KC

Rigid gas‐permeable contact lens for visual rehabilitation in aphakia following trauma [PDF]
Australasian journal of optometry, The, 2012 The aim here was to study the safety and efficacy of fitting a rigid gas-permeable contact lens (RGP CL) for visual rehabilitation in patients with ocular trauma.A retrospective study was performed on 17 aphakic eyes of patients (16 men and one woman) after surgery for ocular trauma. RGP CLs (including nine brown-tinted lenses) were fitted unilaterally
