PURPOSE: To evaluate and compare published methods of calculating intraocular lens (IOL) power following myopic laser refractive surgery. METHODS: We performed a retrospective review of the medical records of 69 patients (69 eyes) who had undergone myopic laser refractive surgery previously and subsequently underwent cataract surgery at Samsung Medical Center in Seoul, South Korea from January 2010 to June 2016. None of the patients had pre-refractive surgery biometric data available...

PURPOSE: To determine the proportion of eyes with preexisting astigmatism achieving 0.50 diopters (D) or less of residual refractive cylinder 3 months after either implantation of toric intraocular lenses (IOLs) or corneal incisions using the VERION system (Alcon Laboratories, Inc., Fort Worth, TX) measurement module and digital markers for microscope (M) and laser (L). METHODS: Eyes with preexisting astigmatism in the intention-to-treat population were divided into four groups...

PURPOSE: To evaluate the outcomes of a new posterior chamber phakic intraocular lens (IPCL; Care Group, Baroda, India) to correct myopia. METHODS: This prospective, observational case series included 30 eyes undergoing implantation of the IPCL for high myopia (> -8.00 diopters [D]). Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, vault, endothelial cell loss, and adverse events were evaluated 3 years after implantation of the IPCL for high myopia...

PURPOSE: To determine in cataract surgery the total surgically induced astigmatism (SIA) that accounts for all factors that contribute to the difference between preoperative keratometric and postoperative refractive astigmatism other than any toricity of an intraocular lens (IOL). SETTING: Twenty surgical sites in the United States. DESIGN: Retrospective case series. METHODS: An analysis was performed of 4 clinical trials involving toric IOLs and nontoric IOLs in standard cataract surgery...

Purpose: To compare the functional and clinical outcomes of the iris-claw intraocular lens (IOL) placed on the anterior versus posterior surface of the iris. Patients and Methods: A multicenter, retrospective study. Data on eyes that underwent anterior or retropupillary iris-claw IOL implantation because of inadequate capsular support secondary to complicated cataract surgery, trauma, and dislocated/opacified IOLs since January 2015 were analyzed. For study inclusion, evaluation results had to be available in the medical records both preoperatively and at 1 and 12 months after implantation...

PURPOSE: To compare visual acuity outcomes of cataract surgery between patients with and without non-glaucomatous optic neuropathies. METHODS: Retrospective case-control study of patients with and without optic neuropathies who underwent cataract surgery from 2010 to 2017. For all eyes, the last preoperative best corrected visual acuity (BCVA) and first BCVA greater than 1 month postoperatively (to ensure sustained refractive stabilization) were recorded in logarithm of the minimum angle of resolution (logMAR) units...

PURPOSE OF REVIEW: To provide a consolidated update regarding preoperative evaluation for cataract surgery. RECENT FINDINGS: Visual acuity alone is a poor gauge of cataract disability. Modalities such as wave front aberrometry, lens densitometry, and light-scatter assessments can quantify optical aspects of cataract and may prove clinically useful in surgical evaluation. Advances in biometry are driving improvements in refractive outcomes, which in turn have increased patient expectations...

Dry eye (DE) causes irregularity of the ocular surface and reduces the quality of vision. An intact, regular tear film is essential for high-quality retinal images; however, visual tasks requiring sustained gazing can disrupt the tear film, eventually degrading visual function. A functional visual acuity (FVA) measurement system has been uniquely developed in Japan to evaluate visual function related to tear stability in patients with DE. FVA has been shown to correlate with optical quality. The system measures the change in visual acuity (VA) over time automatically in aqueous-deficient DE and short tear breakup tear film DE characterized by decreased tear stability and minimal epithelial damage...

BACKGROUND: Older adults in residential aged care facilities have unnecessarily high levels of vision impairment (VI) which are largely treatable or correctable. However, no current comprehensive eye health service model exists in this setting in Australia. We aimed to determine the clinical, person-centered, and economic effectiveness of a novel eye care model, the Residential Ocular Care (ROC). METHODS/DESIGN: This protocol describes a multicentered, prospective, randomized controlled trial...

Purpose: Detecting primary breaks and confirming detachment preoperatively are important. Lincoff stated that retinal detachments progress according to gravity; his law has become popular. We evaluated Lincoff's law with a slight modification to determine whether it remains suitable for present cases independent of refractive error and previous cataract surgery. Patients and methods: Group 1 included superior region detachments not exceeding the 12 o'clock midline; the original break was within 1 1/2 clock hours of the highest detachment border...

Purpose: We report a case of cataract surgery in a patient with a detectable angle gamma due to macular heterotopia. Observation: A 48-year-old man had angle gamma due to macular heterotopia secondary to retinopathy of prematurity. The preoperative corrected distance visual acuity was 20/32 in the right eye and 20/200 in the left eye. Ocular deviation was esotropic at an angle of 70-80prism diopter. Only the right eye was capable of fixating due to the amblyopia in the left eye...

PURPOSE: To compare the clinical outcomes of binocular cataract surgery with and without pinhole corneal inlay implantation. METHODS: In the inlay-cataract group, a small aperture corneal inlay was implanted in addition to cataract surgery in the non-dominant eye and routine cataract surgery was performed in the dominant eye. In the control group, conventional cataract surgery was performed in both eyes in separate consecutive surgeries 2 weeks apart. The target refraction was emmetropia...

Purpose: To evaluate the effect of anterior capsule polishing in patients with high myopia after cataract surgery. Setting: The Eye Hospital of Wenzhou Medical University, Zhejiang, China. Design: Prospective study. Methods: High myopic patients with a bilateral cataract who underwent phacoemulsification with 360° anterior capsular polishing in one eye and without polishing in the contralateral eye were recruited. The following parameters were recorded at 1, 3, and 6 months postoperatively, including the area and diameter of the anterior capsule opening (area and D), IOL tilt and decentration, refraction, and postoperative aqueous depth (PAD)...

PURPOSE: To characterize the optical performance of two models of refractive bifocal intraocular lenses, with medium and high addition, using defocus curves. METHODS: 20 eyes from 20 subjects were included in this study. 10 eyes underwent caratact surgery with an implant of a medium addition refractive bifocal intraocular lens (IOL) (Lentis LS-313 MF20) and the other 10 eyes underwent cataract surgery with an implant of a high addition refractive bifocal IOL (Lentis LS-313 MF30)...

INTRODUCTION: Patients with severe dry eye disease (DED) often have limited treatment options with standard non-surgical management focused on the use of artificial tears for lubrication and anti-inflammatory drugs. However, artificial tears do not address the extraordinary complexity of human tears. Crudely, human tears with its vast constituents is essentially filtered blood. Blood and several blood-derived products including autologous serum, have been studied as tear substitutes. This study proposes to test the use of whole, fresh, autologous blood obtained from a finger prick for treatment of severe DED...

Background: We compared the efficacy between trifocal and bifocal diffractive intraocular lens (IOL) implantation. Methods: Through PubMed, MEDLINE, EMBASE, and CENTRAL, we searched potentially relevant articles published from 1990 to 2018. Defocus curves, visual acuities (VAs) were measured as primary outcomes. Spectacle dependence, postoperative refraction, contrast sensitivity (CS), glare, and higher-order aberrations (HOAs) were measured as secondary outcomes...
