Air bubble-induced intraocular lens opacification in hydrophobic intraocular lens following posttraumatic cataract surgery: A first-ever case report

TNOA Journal of Ophthalmic Science and Research, 2017
A 19 year old male presented with complaints of diminution of vision in right eye. He had undergone cataract surgery in right eye elsewhere 6 years ago for firecracker injury. On examination, eccentric pupil is noticed with intraocular lens (IOL) opacity.

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.

Femtosecond Single‐ and Double‐Pulse Fabrication of Periodic Nanostructures on Stainless Steel for Surface‐Enhanced Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
Periodic submicron features are fabricated on 304 stainless steel using single and double femtosecond laser pulses. By adjusting polarization, fluence, and inter‐pulse delay, 1D and 2D nanostructures are formed. Enhanced hydrophobicity and dense surface‐enhanced Raman spectroscopy hotspots enable analyte detection down to 10−10 M with good ...
