Scanning Electron Microscopy of Hydrophilic Contact Lenses
Archives of Ophthalmology, 1972 Hydrated hydrophilic lenses of three different manufacturers (Griffen, Kontur, and Bausch and Lomb) were prepared for scanning electron microscopy utilizing air drying, freeze drying, and critical point drying techniques. Air dried lenses demonstrated artifacts analogous to those commonly seen in soft biological tissues when prepared in this manner ...

Towards improving the biocompatibility of prosthetic eyes
Heliyon, 2021 Prosthetic eyes are currently manufactured using Poly(methyl methacrylate) (PMMA) which is not an ideal material because it is hydrophobic. While significant research has investigated the benefits of hydrophilic materials for contact lenses, no such ...

Evaluation of thermal disinfection procedures for hydrophilic contact lenses [PDF]
Applied and Environmental Microbiology, 1978 The kinetics and efficacy of moist heat disinfection for hydrophilic contact lenses were investigated by using representative microorganisms of ophthalmic concern and several heat-resistant species. In replicate challenges, 80 degrees C for 10 min and 75 degrees C for 5 min were proven efficacious for moist-heat disinfection.
