Cataract surgery using two 3D visualization systems: Complication rates, surgical duration & comparison with traditional microscopes.

Purpose: To compare the complication rates and surgical duration of cataract surgery using two 3D visualization systems and a traditional binocular microscope among experienced and inexperienced surgeons.

Methods: This retrospective case series included 571 eyes that received cataract surgery using either heads up cataract surgery, via a 3D head mounted system ( = 148-Group 1) or a 3D display screen ( = 338 eyes-Group 2), or traditional binocular microscope ( = 85 eyes-Group 3). The surgical records of consecutive patients who underwent cataract surgery by two groups of surgeons (experienced and inexperienced) were reviewed.

Latanoprostene Bunod 0.024% in Patients with Open-Angle Glaucoma Switched from Prior Pharmacotherapy: A Retrospective Chart Review.

Introduction: Latanoprostene bunod 0.024% (LBN, Vyzulta) is a nitric oxide-donating prostaglandin analog (PGA). We investigated the real-world efficacy and safety of LBN in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT) who switched their existing intraocular pressure (IOP)-lowering treatment(s) to LBN.

Work Intensity of Postoperative Care Following Implantation of Presbyopia-Correcting versus Monofocal Intraocular Lenses.

Purpose: To compare the work intensity of postoperative care following implantation of presbyopia-correcting intraocular lenses (IOLs) to that of standard monofocal IOLs.

Patients And Methods: This open-label, multicenter, comparative study retrospectively reviewed the case records of cataract surgery patients who underwent bilateral implantation of either presbyopia-correcting IOLs (presby-IOL group; N=177) or standard monofocal IOLs (monofocal group; N=177). Outcome measures included the total time the patient spent in the office, number of visits, mean duration of visits, and the number of procedures and diagnostic tests during the first postoperative year.

Use of Cryopreserved Amniotic Membrane During Pterygium Excision: Health Economic Analysis.

Purpose: To determine the health economic opportunity cost or gain associated with performing pterygium excision surgery using the TissueTuck technique with cryopreserved amniotic membrane (AM) instead of conjunctival autograft (CAU).

Methods: We performed a literature review to determine the average surgical duration of pterygium surgery using CAU with fibrin glue or sutures to calculate the average time saved with the TissueTuck technique. Such time savings was then used to determine the opportunity revenue gain per national average Medicare reimbursement if adjusted to the average surgical duration of cataract surgery.

Outcomes of the TissueTuck Surgical Technique for Recurrent Pterygium.

Purpose: The objective of this study was to evaluate the clinical outcomes of the TissueTuck technique in the treatment of eyes with recurrent pterygium.

Methods: A retrospective review was performed on patients with recurrent pterygium who underwent surgical excision, followed by the application of cryopreserved amniotic membrane, using the TissueTuck technique between January 2012 and May 2019. Only patients with at least 3 months of follow-up were included for analysis.

Cryopreserved Amniotic Membrane Using the TissueTuck Technique: A Sutureless Approach for Pterygium Surgery.

Purpose: The purpose of this study was to evaluate the clinical outcomes of the TissueTuck technique in the management of pterygium.

Methods: This was a single-center, retrospective review of patients with primary or recurrent pterygium that underwent surgical excision followed by application of cryopreserved amniotic membrane (AM) using the TissueTuck technique. All patients underwent surgery between January 2012 and May 2019.

First Real-World, Multicenter, Post-Marketing, Retrospective Study of Dexamethasone Intraocular Suspension for Inflammation After Cataract Surgery.

Purpose: To evaluate dexamethasone intraocular suspension 9% (intraocular DXM) in real-world clinical use to manage inflammation associated with cataract surgery.

Setting: Patients who underwent cataract surgery and received intraocular DXM at 22 outpatient eye surgery centers in the US.

Design: Retrospective, observational chart review.

Outcomes of toric IOL implantation guided by iris-registered femtosecond laser capsulotomy markings.

Purpose: To assess the accuracy and stability of iris-registered femtosecond laser-assisted anterior capsule axis markings (compensating cyclotorsion) along with refractive and visual outcomes after toric IOL implantation.

Methods: This prospective case series included eyes with visually significant cataracts and regular corneal astigmatism ranging from 1.25D to 4.

Argentinian Flag Sign and Its Management during Femtosecond Laser-Assisted Cataract Surgery in a Case with Intumescent Cataracts.

We describe a case of radial extension and its management during femtosecond laser-assisted cataract surgery (FLACS) in a patient with intumescent cataracts. Radial extension was observed after injection of trypan blue into the anterior chamber. Management of the extension was achieved by separation of adhesions between the incomplete capsulotomy, along with manual completion at the areas of extensions.

Optical Coherence Tomography Angiography in Neurodegenerative Diseases: A Review.

Background: Optical coherence tomography angiography (OCT-A) has emerged as a novel, fast, safe and non-invasive imaging technique of analyzing the retinal and choroidal microvasculature in vivo. OCT-A captures multiple sequential B-scans performed repeatedly over a specific retinal area at high speed, thus enabling the composition of a vascular map with areas of contrast change (high flow zones) and areas of steady contrast (slow or no flow zones). It therefore provides unique insight into the exact retinal or choroidal layer and location at which abnormal blood flow develops.

Descemetorhexis Without Endothelial Keratoplasty Versus DMEK for Treatment of Fuchs Endothelial Corneal Dystrophy.

Purpose: To compare the visual outcomes and associated morbidity of patients with Fuchs endothelial corneal dystrophy who were treated with either Descemet membrane endothelial keratoplasty (DMEK) or descemetorhexis without endothelial keratoplasty (DWEK).

Methods: This is a retrospective comparative cohort study of 27 eyes with mild to moderate Fuchs dystrophy (with corneal guttae/edema limited to the central cornea with relatively clear periphery) that were treated at the University of Pittsburgh Medical Center from 2015 to 2017 with either DMEK (n = 15) or DWEK (n = 12). Descemetorhexis was performed by removing the central 4 mm of diseased Descemet membrane at the end of phacoemulsification for cataract surgery.

The Effect of NSAID Pretreatment on Aqueous Humor Prostaglandin E Concentration in Eyes Undergoing Femtosecond Laser-Assisted Capsulotomy.

Purpose: To assess aqueous humor concentration of prostaglandin E (PGE) after capsulotomy creation using a femtosecond laser (FLAC) in patients pretreated with short-term topical ketorolac versus patients without pretreatment.

Methods: This prospective study comprised consecutive patients scheduled to undergo cataract surgery using a femtosecond laser platform to perform only capsulotomies. An identical protocol for preoperative mydriasis was used for all the eyes included in the study, while aqueous humor was extracted from the anterior chamber of all patients immediately after the initial side port incision.

Crystalline lens endocapsular fragmentation using an elastic loop filament.

Purpose: To describe a novel mechanical endocapsular fragmentation technique of the crystalline lens during cataract surgery using a loop elastic-thin filament.

Methods: An alternative method to mechanically fragment the crystalline lens utilizing a nitinol loop is described. This device achieves lens sectioning in multiple pieces, decreasing ultrasonic energy expenditure during cataract surgery.
