Therapeutic use of soft contact lenses.
Soft contact lenses are widely used for correction of refractive errors and in diseases related to corneal surface irregularities. In this case series we have used soft contact lenses in treatment of patients having bullous keratopathy, corneal ulcer, dry eye, trichiasis and corneal perforation. Soft contact lenses were found to be superior than conventional method of treatment and they have re...
متن کاملPermeability of hydrophilic contact lenses.
Oxygen permeability and water diffusion characteristics were determined for several types of hydroxyethyl-methacrylate hydrophilic contact lenses and a silicone contact lens material. A twoto fourfold difference in the diffusion rates for capillary flow of water was found among the different hydrophilic lenses. Oxygen permeability studies demonstrate that the hydrophilic lenses are capable of t...
متن کاملEvaluation of thermal disinfection procedures for hydrophilic contact lenses.
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.
متن کاملOcular Drug Delivery through pHEMA-Hydrogel Contact Lenses Co-Loaded with Lipophilic Vitamins
Ocular drug delivery through hydrogel contact lenses has great potential for the treatment of ocular diseases. Previous studies showed that the loading of lipophilic vitamin E to silicone-hydrogel contact lenses was beneficial in ocular drug delivery. We hypothesized that vitamin E loading to another type of popular hydrogel contact lenses, pHEMA-hydrogel contact lenses, improves ocular drug de...
متن کاملEffect of conventional hard and hydrophilic soft contact lenses on the corneal epithelium. Comparative study in tissue culture.
The evolution of pathological changes in the corneal epithelium may be studied by tissue culture methods. We have examined the effects of conventional hard contact lenses and hydrophilic soft lenses, in order to study the effect of the direct pressure of such lenses on the corneal epithelium and the effect of prolonged oxygen deprivation on cell growth. We have also observed the time of onset o...
