Comparison of keratometry using SS-OCT and dual Scheimpflug-Placido imaging in postmyopic corneal refractive surgery eyes.

Purpose: To compare simulated (SimK) and total (True-K) keratometry and corneal astigmatism values between the IOLMaster 700 (IOLM) and Galilei G4 (G4) devices in postmyopic laser refractive surgery eyes.

Setting: Methodist Eye Associates, Blanton Eye Institute, Houston Methodist Hospital, Houston, Texas.

Design: Retrospective cohort study.

Comparison of Simulated and True Keratometry Measurements Using Swept-Source Optical Coherence Tomography and Dual Scheimpflug-Placido Imaging.

Purpose: To compare simulated and total keratometry and corneal astigmatism values between the IOLMaster 700 and Galilei G4 devices.

Methods: A retrospective chart review was conducted for all patients undergoing phacoemulsification by a single surgeon (RTP) from March through September 2020 and who underwent imaging with both the IOLMaster 700 and Galilei G4. Exclusion criteria were prior corneal surgery, keratectatic diseases and inability to obtain a reliable image during image acquisition.

Orbital Compartment Syndrome After High-speed Air-Gasoline Blast Injury.

Orbital compartment syndrome is an ophthalmologic emergency that requires timely surgical intervention. The authors present a rare case of orbital compartment syndrome in a 30-year-old male injured by forceful entry of air-gasoline mixture into the orbit, secondary to inadvertent firing of the piston from running mechanical diagnostics on an automobile internal combustion engine. Orbital CT revealed extensive orbital emphysema with both pre- and postseptal involvement and diffuse chemical cellulitis.

Twist and out intraocular lens removal.

Foldable acrylic posterior chamber intraocular lenses (PC IOLs) can be removed via a variety of methods. In this technique, the PC IOL is freed from its position in the capsular bag or sulcus space and raised into the anterior chamber. The IOL is manipulated such that a haptic is externalized through a 2.

Monocular Clinical Outcomes and Range of Near Vision following Cataract Surgery with Implantation of an Extended Depth of Focus Intraocular Lens.

Importance: A full range of near and intermediate vision has not been clinically evaluated for the Symfony extended depth of focus intraocular lens (EDOF IOL).

Background: To evaluate the monocular range of near visual acuity with an EDOF IOL.

Design: Retrospective case series.

Shewanella algae keratitis.

A 75-year-old male with a right eye history of chronic dry eye syndrome, glaucoma status post tube shunt, and Fuchs dystrophy status post Descemet stripping endothelial keratoplasty followed by penetrating keratoplasty (PKP) presented with a 2.7 × 4.2 mm corneal ulcer, culture positive for Shewanella algae and Klebsiella oxytoca.

Antibiotic Resistance Rates by Geographic Region Among Ocular Pathogens Collected During the ARMOR Surveillance Study.

Introduction: The Antibiotic Resistance Monitoring in Ocular micRoorganisms (ARMOR) study is an ongoing nationwide surveillance program that surveys in vitro antibiotic resistance rates and trends among ocular bacterial pathogens. We report resistance rates by geographic region for isolates collected from 2009 through 2016.

Methods: Staphylococcus aureus, coagulase-negative staphylococci (CoNS), Streptococcus pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa isolates from ocular infections were collected at clinical centers across the US and categorized by geographic region based on state.

Comparison of Anterior Chamber Depth Measurements from the Galilei Dual Scheimpflug Analyzer with IOLMaster.

Purpose. To compare anterior chamber depth (ACD), representing the distance between the anterior corneal surface and anterior lens surface measurements between the Galilei Dual Scheimpflug Analyzer and the IOLMaster. Methods.

Brevundimonas diminuta keratitis.

Purpose: To report the first documented case of keratitis secondary to the gram-negative bacillus Brevundimonas diminuta.

Methods: A 66-year-old woman with an ocular history of bilateral soft contact lens wear presented with a large, 6×9-mm, culture-positive Pseudomonas aeruginosa-induced corneal ulcer. After weeks of therapy, she developed secondary keratitis.

Sudden corneal edema due to retained lens nuclear fragment presenting 8.5 years after cataract surgery.

A 79-year-old woman presented with a 1-week history of sudden onset of decreased vision, pain, and redness in the right eye. Ocular history included uneventful cataract surgery in both eyes more than 8 years prior to presentation. Slitlamp examination revealed significant corneal edema and mild iritis.

Tent-shaped retinal detachments in retinopathy of prematurity.

Background: Most retinal detachments associated with retinopathy of prematurity (ROP) are radial, segmental, or circumferential with cicatricial extraretinal fibrovascular proliferation (EFP) at the apex of the detachment. This report describes peculiar tent-shaped retinal detachments that developed among eyes with ROP.

Methods: An observational case series consisting of 9 patients and 13 eyes with tent-shaped retinal detachments.

Pop-and-chop nucleofractis.

Horizontal chopping is effective for endocapsular nucleofractis. We describe pop and chop, a variant of chopping that enables an easy first crack and initial segment removal. It involves partial extracapsular prolapse of the nucleus prior to the initial chop.
