PURPOSE To compare the astigmatic power of toric intraocular lenses (IOLs) obtained from the AcrySof, TECNIS, and iTrace toric calculator in patients with preoperative with-the-rule (WTR) or against-the-rule (ATR) corneal astigmatism. MATERIALS AND METHODS Fifty eyes with cataract and corneal astigmatism greater than 0.75 diopters were enrolled in each group (WTR and ATR). Keratometric values...

PURPOSE To evaluate refractive results with a low-cylinder-power toric intraocular lens (IOL) and the effect of preoperative corneal astigmatism orientation on results. SETTING Private practice, Jackson, Michigan, USA. DESIGN Comparative case series. METHODS This retrospective review of clinical records comprised patients with 0.75 to 1.38 diopters (D) of preoperative corneal astigmatism ...

We present the case of a 73-year-old patient who underwent successful phacoemulsification and toric intraocular lens (IOL) implantation to correct high stable astigmatism due to keratoconus and cataract. Preoperative refraction was –3.25 – 4.0 × 98°. A toric IOL (Acrysof SN60T6) with a spherical power of 16.5 D and a cylinder power of 3.75 D at the IOL plane and 2.57 D at the corneal plane was ...

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...

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...

PURPOSE To study the outcomes of toric and multifocal intraocular lens (IOL) implantation performed by resident surgeons. SETTING Parkland Health and Hospital System, Dallas, Texas, USA. DESIGN Case series. METHODS Patients seen between July 2008 and May 2011 and meeting inclusion criteria (including >1.0 diopter [D] of astigmatism in toric group and <0.75 D astigmatism in multifocal grou...

UNLABELLED This report describes 6 cases in which neodymium:YAG (Nd:YAG) laser anterior capsulectomy achieved limited success in treating negative dysphotopsia. In 5 eyes with the Akreos AO MI60L posterior chamber intraocular lens (PC IOL), the dysphotopsia symptoms resolved completely (3 eyes) and partially (2 eyes) depending on the extent of the Nd:YAG laser anterior capsulectomy. In 1 eye wi...
