Refractive cataract surgery

Benjamin R LaHood, Michael Goggin, Simone Beheregaray, Nicholas H Andrew, Adrian Esterman
PURPOSE: To compare "total keratometry" measurements with Goggin nomogram adjusted anterior keratometry (GNAK) for toric intraocular lens calculation. METHODS: Routine biometry provided measured total keratometry values from which astigmatism was derived. The Goggin nomogram was applied to anterior keratometry values on the same eyes to provide nomogram-adjusted anterior keratometry values (GNAK) that estimate total corneal astigmatism. The agreement between total keratometry and GNAK was analyzed...

Patients who have had previous refractive procedures often require cataract surgery at an early age; however, postoperative results are compromised by corneal aberrations and difficulties achieving a desired refractive endpoint. We describe the use of the IC-8 small-aperture intraocular lens (IOL) in 3 patients who had previous laser in situ keratomileusis (LASIK). Standard cataract surgery was performed in all cases. The small-aperture IOL was implanted in the patient's nondominant eye, and a clear aspheric monofocal IOL was implanted in the dominant eye...

We describe a case of indapamide-induced bilateral choroidal effusion, first time reported in pseudophakic patient, associated with no change in visual acuity and stable refraction.A 70-year-old man was referred for ophthalmic assessment, with binasal visual field defect for 2 days. He had been started on treatment with indapamide 3 weeks earlier. His ophthalmic history included bilateral cataract surgery and intraocular lens implant. Fundal examination revealed bilateral choroidal effusions; B-scan ultrasonography was used to measure the extent of the choroidal detachment and the anterior chamber depth...

PURPOSE: To assess the accuracy of different methods to calculate the intraocular lens (IOL) power from measurements obtained with an optical biometer combined with a Placido disk-Scheimpflug tomographer (Galilei G6) in eyes that had previous myopic excimer laser surgery. SETTING: G.B. Bietti Foundation, Rome, Italy. DESIGN: Prospective case series. METHODS: When prerefractive surgery data were available, the following methods were evaluated: the Barrett True-K, total corneal power 1 (TCP 1) with double-K SRK/T, TCP with double-K Holladay 1, as well as the Masket and Savini methods...

Purpose: To present the outcomes of hybrid multifocal and monofocal intraocular lenses (IOLs) and to compare with refractive and diffractive multifocal IOLs (MFIOLs). Methods: Three hundred twenty eyes (160 patients) underwent cataract surgery with randomized IOLs bilateral implantation. Changes in uncorrected and distance-corrected logMAR distance, intermediate and near (UNVA and DCNVA) visual acuity (VA), contrast sensitivity (CS), presence of dysphotopsia, spectacle independence, and patient satisfaction were analyzed...

PURPOSE: To describe a case of Posterior Keratoconus (keratoconus posticus); its clinical condition, corneal, refractive response to intracorneal ring implantation (MyoRing), anterior segment optical coherence tomography findings; and micro incisional cataract surgery outcome. METHODS: Case report. RESULTS: The case was studied with high resolution anterior segment optical coherence tomography (OCT), epithelium OCT, corneal topography, and aberrometry...

PURPOSE: Corneal hysteresis (CH) is a corneal biomechanical property measured by the ocular response analyzer (ORA). It is associated with primary open-angle glaucoma development, progression, and severity as well as intraocular pressure (IOP) measurement. Decreases in CH and changes in IOP measurements have been described for laser-assisted refractive surgery; however, patients with prior radial keratotomy (RK) have not been examined. We have performed a cohort study examining CH and intraocular pressure measurements (Goldmann applanation and ORA values including Goldmann-correlated and cornea-compensated IOP [adjusted for corneal hysteresis]) in RK patients and myopic controls with POAG...

As cataract surgery continues to evolve, the intraoperative small pupil continues to pose challenges to even the most experienced cataract surgeon. Several steps can be taken preoperatively to decrease the chance of intraoperative miosis. Even so, the problem of miosis during cataract surgery remains a relatively common occurrence. This paper discusses many steps, both preoperative and intraoperative, that can make surgery technically easier and safer, thus maximizing the postoperative outcomes and patient satisfaction...

BACKGROUND: Intraocular lenses (IOLs) with different diopter (D) intervals may have different tolerance, and may provide different accuracy of refractive outcome after cataract surgery. The aim of the study is to compare the accuracy of refractive outcome after implantation of IOLs with different D intervals after cataract surgery. METHODS: A total of 80 eyes from 40 patients who underwent phacoemulsification with implantation of a 0.50 D interval Akreos AO IOL in one eye and a 0...

Purpose: To report clinical results of a foldable, hydrophilic acrylic, single-piece, injectable, posterior chamber phakic intraocular lens (pIOL). Material and Methods: Medical records of patients who underwent posterior chamber phakic IOL (Eyecryl Phakic IOL, Biotech Vision Care, Ahmedabad, India) implantation for surgical correction of myopia were retrospectively reviewed. Only patients with at least a one-year follow-up were included. Manifest refraction, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), endothelial cell density (ECD), and pIOL vault were analyzed at 1, 3, 6, and 12 months after surgery...

Background: Advancements in cataract surgery have necessitated the availability of intraocular lens preloaded delivery systems that can safely, effectively and predictably deliver IOLs in the eye. Preloaded delivery systems simplify and reduce procedural variability during surgery preparation. Objective: The objective of this study was to evaluate clinical acceptability, delivery characteristics and clinical outcomes in patients implanted with new generation hydrophobic acrylic Intraocular Lens with Preloaded delivery system...
