An inductive approach to classifying all toric Fano varieties is given. As an application of this technique, we present a classification of the toric Fano threefolds with at worst canonical singularities. Up to isomorphism, there are 674,688 such varieties.

The aim of this study was to compare the visual performance of Acrysof ReSTOR and Acrysof Natural intraocular lenses (IOLs) following cataract surgery. A randomized prospective study was performed in which 64 eyes (51 patients) were divided randomly into two groups. Monofocal IOLs (Acrysof Natural) were implanted into 34 eyes (27 patients) and multifocal IOLs (Acrysof ReSTOR) were implanted int...

Blue light can damage retina and cause age related macular degeneration. After cataract surgery and lens removal retina stays unprotected. Blue light filtering intraocular lenses (IOL) increase protection of the retina. In our prospective study we investigated clinical results after bilateral implantation of Acrysof Natural IOL to 30 patients (N = 60 eyes). In a control group (N = 60 eyes, 30 p...

PURPOSE To evaluate the efficacy, stability, predictability, and patient-reported outcomes of bilateral toric intraocular lens (IOL) implantation in cases of cataract with preexisting astigmatism. SETTING Fourteen universities, hospitals, or private practices, Canada. METHODS Patients with cataracts and corneal astigmatism from 1.00 to 2.50 diopters (D) were included in a prospective study ...

PURPOSE To evaluate mesopic visual acuity and visual quality as measured by objective scatter index (OSI) in pseudophakic eyes with long-term follow-up after implantation of hydrophobic acrylic lenses made from two different lens materials. SETTING This study was carried out in a private clinic. DESIGN This study was an observational cohort study. METHODS This pilot study included 181 eye...

OBJECTIVE To compare the lifetime costs of freeing astigmatic patients from spectacles after bilateral cataract surgery implanting toric intraocular lenses (IOLs: i.e., Acrysof Toric) versus monofocal IOLs, in France, Italy, Germany and Spain. METHODS A Markov model followed patient cohorts from cataract surgery until death. Prevalence rates of patients not needing spectacles and the types of...

PURPOSE To evaluate the refractive and visual outcome of toric IOL implantation for correction of pre-existing corneal astigmatism following cataract surgery. MATERIALS AND METHODS In this retrospective study, 56 eyes of 30 patients who underwent implantation of toric IOL following regular phacoemulsification were divided into two groups based on the types of toric IOL implanted: group 1 pati...

purpose : to evaluate the efficacy, safety, predictability and stability of implantable collamer lens (icl) and toric icl for the treat­ment of high myopia and high myopic astigmatism methods : in this prospective nonrandomized clinical trial, 95 eyes of 51 patients who underwent icl (31 eyes) and toric icl (64 eyes) implantations were participate in eye research center, department of ophthalmo...
