Rigid gas-permeable contact lens–assisted cataract surgery in patients with severe keratoconus
Journal of Cataract and Refractive Surgery, 2014 We describe rigid gas-permeable (RGP) contact lens-assisted cataract surgery in patients with severe keratoconus. During cataract surgery in cases with severe keratoconus, the intraocular images are distorted and visual perspective is lost because of irregular corneal astigmatism.

Acute rigid gas permeable contact lens intolerance
Contact Lens and Anterior Eye, 2001Rigid gas permeable (RGP) and polymethylmethacrylate (PMMA) lens wearers occasionally report episodes of acute intolerance which is experienced upon lens insertion. In this paper, we report two cases of such intolerance in which the probable cause was contact lens inversion.

Rigid gas permeable contact lens and corneal topography
Ophthalmic and Physiological Optics, 2001SummaryWe investigated the effect of high Dk daily wear rigid gas permeable contact lenses on corneal topography. Eight young myopic subjects wore hard contact lenses for 21 days. Corneal topography was monitored using the EyeSys system. It was measured every day during the next 21 days after the fitting.

Corneal tomographic changes during corneal rigid gas-permeable contact lens wear in keratoconic eyes
British Journal of Ophthalmology, 2020Background/Aims We aimed to investigate the refractive changes in the posterior corneal surface in keratoconus (KC) associated with wearing spherical corneal rigid gas-permeable contact lenses (corneal GPs) with apical touch or three-point touch fitting ...

Clinical Investigation of the Paraperm EW Rigid Gas-Permeable Contact Lens
Optometry and Vision Science, 1987Paraperm EW is a high oxygen flux silicone/acrylate rigid lens material currently under clinical investigation for extended wear. The purpose of this paper is to report the clinical findings after 12 months of a 2-year investigation of 18 patients fitted with this material. Fifteen were successfully wearing Paraperm EW lenses at 1 year.
