SUBJECT: The main objective of our study is to evaluate the contribution of automated conjunctival recognition in the alignment of toric implants by comparing the automatic alignment optimized with Callisto™ to the manual marking of the horizontal axis. MATERIALS AND METHODS: We performed a prospective, descriptive, and monocentric study on patients undergoing cataract surgery with toric implantation (Asphina 709 Zeiss), operated by a surgeon with good experience in toricity, between September 2016 and March 2017...

PURPOSE: To compare the rotational stability, total misalignment, and visual and refractive outcomes achieved with a trifocal toric versus a monofocal toric intraocular lens (IOL). METHODS: In this prospective, interventional case series, eyes of patients consecutively scheduled for cataract surgery who had clinically relevant astigmatism were implanted with a FineVision Pod FT trifocal toric IOL or an Ankoris monofocal toric IOL (both PhysIOL SA, Liège, Belgium)...

We report the case of an emmetropic 32-year-old female with decreased uncorrected visual acuity and diplopia due to intermittent episodes of spasm of the near reflex. Neurologic, general, and ophthalmic examination could not find an organic cause. Attempts at spontaneous recovery, psychogenic therapy, and cycloplegic therapy were unsuccessful and the symptoms persisted for almost 5 years, leading to psychogenic distress. Final treatment with refractive lens exchange and implantation of a toric trifocal intraocular lens resolved the spasm of the near reflex, resulting in an uncorrected distance and near visual acuity of 20/20...

BACKGROUND: With increasing availability of toric intraocular lenses (IOL) for cataract surgery, real-world refractive outcome data is needed to aid the counselling of patients regarding lens choice. We aim to assess the outcomes of toric intraocular lens use in the non-specialist environment of a typical United Kingdom NHS cataract service. METHODS: A retrospective cohort study conducted at the Oxford Eye Hospital, Oxford University Hospitals NHS Foundation Trust, UK...

INTRODUCTION: The published literature on toric intraocular lenses (IOL) reports postoperative refractive cylinder less than or equal to 0.5 D in anywhere from 25% to 100% of implantations with both the Acrysof ® Toric and Tecnis ® Toric IOL, depending upon the article. However, the majority of articles tend to cite rates between 70% and 80%. PURPOSE: The purpose was to evaluate my personal outcomes for both models of toric IOL, in terms of one-month postoperative refractive cylinder, after implementation of new methods of IOL selection, calculation and implantation...

An impaired ocular surface adversely affects preoperative planning for cataract surgery, including intraocular lens (IOL) calculations, toric IOL axis and magnitude estimates, keratometry, and topography measurements. It also increases surgical difficulty. We performed a review to evaluate the connection between cataract surgery and dry eye and to determine the best management for these patients. Of the 16 papers included in this review, 6 were randomized controlled trials. Cataract surgery was shown to worsen ocular parameters and aggravate dry-eye disease...

PURPOSE: To determine whether use of a capsular tension ring (CTR) can increase refractive stability in patients with implantation of two different trifocal intraocular lenses (IOLs). METHODS: A prospective, consecutive series of eyes underwent refractive lens exchange with implantation of two different trifocal IOL designs: FineVision Micro F (non-toric) and FineVision POD FT (toric) (PhysIOL, Liege, Belgium). Power calculation was determined using the Haigis formula...

PURPOSE: To compare the prediction error in the calculation of toric intraocular lenses (IOLs) associated with methods that estimate the power of the posterior corneal surface (ie, Barrett toric calculator and Abulafia-Koch formula) with that of methods that consider real measures obtained using Scheimpflug imaging: a software that uses vectorial calculation (Panacea toric calculator: http://www.panaceaiolandtoriccalculator.com) and a ray tracing software (PhacoOptics, Aarhus Nord, Denmark)...

Prakhyat Roop
In existing designs of intraocular lenses (IOLs), optical outcomes are compromised even after perfectly executed surgery. The reason for this is misalignment of optical axis of the eye and its visual axis. There is a need to design an IOL which compensates for this misalignment and hence enhances the optical outcomes of cataract surgery. The present innovation attempts to fulfill this unmet need and optimizes optical outcomes of all IOLs of different optical profiles - spherical, aspheric, toric, and multifocal...

Toric intraocular lenses (IOLs) are the procedure of choice to correct corneal astigmatism of 1 D or more in cases undergoing cataract surgery. Comprehensive literature search was performed in MEDLINE using "toric intraocular lenses," "astigmatism," and "cataract surgery" as keywords. The outcomes after toric IOL implantation are influenced by numerous factors, right from the preoperative case selection and investigations to accurate intraoperative alignment and postoperative care. Enhanced accuracy of keratometry estimation may be achieved by taking multiple measurements and employing at least two separate devices based on different principles...

Background: To assess the clinical consequences of AcrySof toric intraocular lens (IOL) and Hoya toric IOL implantation to correct preexisting corneal astigmatism in patients undergoing cataract surgery. Materials and Methods: In this study, we examined 55 eyes of 45 patients with at least 1.00 D corneal astigmatism who were scheduled for cataract surgery. After phacoemulsification, toric IOL was inserted and axis was aligned. We observed the patients, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry, manifest refraction, and IOL axis alignment 6 months after surgery...

This study examined resident exposure to and competency in new techniques for cataract removal and intraocular lens (IOL) implantation. A questionnaire was sent to 116 United States ophthalmology program directors and completed by 71. In response to the questionnaire, program directors reported that 95.3% of their graduating seniors were competent to select and implant toric IOLs and 52.3% were competent to implant capsular tension rings (CTRs). Divide and conquer (56.6%) and stop and chop (25.4%) dominated phacoemulsification teaching...

A young patient underwent phacoemulsification with endocapsular implantation of trifocal toric lens in both eyes (AT LISA tri toric 939 MP, Carl-Zeiss, Germany). One-week postsurgery, he developed capsular block syndrome (CBS) in both eyes. There was deterioration of uncorrected visual acuity at 1-week postsurgery, with a myopic shift of 2.5 diopters (D) in the right eye and 2.0 D in the left eye. The intraocular pressure was only elevated in the left eye. Neodymium: yttrium-aluminum-garnet laser posterior capsulotomy resolved the block successfully in both eyes...

PURPOSE: To describe the good outcome of implantable collamer lens (ICL) rotation to reduce post-operative vault. METHODS: Retrospective analysis of case report. A 43-year-old woman had V4c EVO + myopic non-toric ICL implantation and post-operatively she presented with anisocoria and high vault. She underwent surgery to rotate the ICL 90 degrees to a vertical orientation. RESULTS: We achieved a reduction in the vault from 1020 to 486 μm after vertical ICL rotation...

Pankaj C Gupta, Jane T Caty
PURPOSE OF REVIEW: To evaluate and summarize literature from the past 18 months reporting advancements and issues in astigmatism assessment prior to cataract surgery. RECENT FINDINGS: New and updated toric calculators and regression formulas offer the opportunity for more accurate lens selection for our patients. Concurrently, improvements in topographic evaluation of corneal keratometry have allowed for a decrease in unplanned residual corneal astigmatism. Measuring posterior corneal astigmatism is especially valuable in eyes with keratoconus when planning to implant toric intraocular lens (IOL) and now allows access to this patient population...

PURPOSE: The purpose of this study was to provide clinical outcomes data related to secondary intraocular lens (IOL) implantation for the correction of residual refractive error after cataract surgery. PATIENTS AND METHODS: A chart review was conducted to identify all eyes implanted with the monofocal spherical or toric AddOn(®) secondary IOL. Data were collated from charts where uncomplicated initial cataract surgery was completed. Measures of interest included the original IOL implanted, the postoperative refractive error (before secondary IOL implantation) and the associated corrected and uncorrected visual acuities (VAs)...
