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 ...

OBJECTIVE AND METHOD To describe a surgical technique that enables diffractive lenses with open-loop haptics to be centered on the chosen optical axis. To perform this, the desired axis must initially be marked on the cornea, the rhexis must be aligned with this, and once the intraocular lens (IOL) is implanted in the capsular bag, it is aligned by intracapsular rotation to match the central ri...

PURPOSE To compare higher order aberrations (HOA) in AcrySof SN60AT and Acrysof IQ SN60WF intraocular lenses (IOLs) and natural crystalline lenses in an age-matched population. METHODS Sixty-nine eyes of 55 patients were examined. Group I included AcrySof spheric lenses, group II AcrySof aspheric lenses, and group III included patients with the natural crystalline lens. The HOA data were obta...

Aim: To design an accommodating intraocular lens with extended accommodative range that can be adapted to current standard phacoemulsification and endocapsular implantation technique. Method: Ray tracing analysis and lens design; cadaver eye implantation. Results: Ray tracing analysis indicated that axial movement of an exaggerated converging anterior optic linked by spring loaded haptics to a ...

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...

PURPOSE To evaluate intraindividual visual acuity, wavefront errors and modulation transfer functions in patients implanted with two diffractive multifocal intraocular lenses. METHODS This prospective study examined 40 eyes of 20 cataract patients who underwent phacoemulsification and implantation of a spherical multifocal ReSTOR intraocular lens in one eye and an aspheric Tecnis ZM900 multif...
