Background: Surgical teaching seems to be in conflict with the contract between surgeon and patient. We carried out a study to determine the prevalence of consistent disclosure to patients that a resident will perform part or all of their cataract surgery procedure.A second objective was to investigate the effect of such disclosure on patients' willingness to undergo the procedure.Methods: We sent...
Background: Cataract surgery in a population with mild levels of functional impairment was studied in the Regional Evaluation of Surgical Indications and Outcomes (RESIO) project.The RESIO investigators assessed the overall visual function assessment (VFA) score before and after surgery. In this study we reanalysed available RESIO data to better understand the findings for individual VFA items in...
Background: Maximum mydriasis and corneal clarity during intraocular surgery are important to ensure operational safety. However, repeated instillation of mydriatic and anti-inflammatory ophthalmic solutions during surgery may affect compliance and may damage the corneal epithelium.We developed an ophthalmic solution containing tropicamide, phenylephrine hydrochloride and diclofenac sodium, and compared...
Background: Intravitreal injection of triamcinolone acetonide appears to be a promising treatment for a variety of proliferative, edematous, neovascular and inflammatory ocular disorders. Reported complications include intraocular pressure (IOP) elevation, cataract formation, retinal detachment, vitreous hemorrhage and endophthalmitis.The purpose of this investigation was to report the complications...
Background: Ocular surface-related discomfort is the main reason for stopping contact lens wear. We carried out a study to evaluate the efficacy of preservative-free artificial tears containing 0.9% sodium chloride on ocular surface signs and symptoms in contact lens wearers experiencing discomfort and its possible influence on the duration of contact lens wear.Methods: We studied 49 contact lens...
Background: A higher than expected rate of anophthalmia/microphthalmia (A/M) for 1999 was noted in both the Alberta Congenital Anomalies Surveillance System (ACASS) and the Canadian Congenital Anomalies Surveillance System (CCASS).Since this increase was at variance with the previous 19 years, we performed a review to determine whether the increase was true and, if so, the possible explanation.Methods:...
Background: It has been postulated that migraine and glaucoma may have common vascular causative factors. Significant sex-based differences in the incidence of many important ocular conditions raise the possibility that estrogens may have direct effects on the eye.We performed a study to determine the effect of the menstrual cycle on standard achromatic automated perimetry (SAP) and short-wavelength...
