The use of hydrophilic soft contact lenses for dispensation of pilocarpine is described. The release rate of pilocarpine from three materials of different water content was estimated and from this the surface concentrations were calculated. It is estimated that PolyHEMA can after 15 hours provide a 1 per cent surface concentration of pilocarpine, whereas higher water content materials (70 and 8...

PURPOSE This study is a cross-sectional analysis of the types and prevalence of contact lens (CL)-related complications among CL wearing patients seen in a university clinic setting. METHODS Data on CL material and design, care system, and ocular complications were recorded and statistically analyzed for CL wearers. RESULTS Of the 572 patients (846 eyes) recruited during the study, approxim...
purpose: to determine the sensitivity and specificity of confocal scan in the diagnosis of fungal and acanthamoeba keratitis based on the results of corneal and/or contact lens case smear and culture. method: confocal scan and corneal and/or contact lens case smear and culture were performed in all patients with a clinical diagnosis of infectious keratitis who were referred to labbafinejad medi...
