PURPOSE To describe the use of argon laser iridoplasty following implantation of a multifocal intraocular lens (IOL) to improve visual function. METHODS Argon laser spots of 500-mW power, 500-μm spot diameter, and 500-ms duration were placed in the midperipheral iris in the area in which the iris was encroaching on the IOL. RESULTS Argon laser iridoplasty provided statistically significant ...
PURPOSE To determine the efficacy of the astigmatism correction following toric intraocular lens (IOL) and toric phakic IOL (pIOL) implantation in eyes with no previous ocular surgery and in postkeratoplasty (PKP) eyes. In addition, changes in corneal astigmatism were determined. METHODS Astigmatism was analyzed in 35 eyes with an AcrySof toric IOL, 35 eyes with an Artiflex toric pIOL, 50 eye...
UNLABELLED This article presents an extensive overview of best clinical practice pertaining to selection and use of multifocal intraocular lenses (IOLs) currently available in the United States. Relevant preoperative diagnostic evaluations, patient selection criteria, counseling, and managing expectations are reviewed, as well as how to approach patients with underlying ocular intricacies or ch...
In the current era of presbyopia-correcting intraocular lenses (IOLs), toric IOLs and aspheric IOL technology, the practice milieu is changing. Informed consent takes on newmeaning when the surgeon and the patient decide together which IOL technology represents the best fit for a particular life style and its visual demands. Customizing IOL choice is no longer optional; it is essential to the p...
PURPOSE To analyze intraocular lens (IOL) orientation data from an online toric back-calculator (astigmatismfix.com) for determining if differences were apparent by lens type. METHODS A retrospective review of astigmatismfix.com toric back-calculations that included IOL identification and intended orientation axis. RESULTS Of 12,812 total validated calculation records, 8,229 included intend...
PURPOSE To determine the refractive cylinder effect of rotating a toric intraocular lens (IOL) and identify the sources of refractive astigmatic surprise after toric IOL implantation. SETTING Private practice, Melbourne, Australia. DESIGN Experimental study. METHODS Vergence formulas using a standard reduced eye model were used to bring all lens powers to the corneal plane. Double-angle v...
