Prospective randomized clinical trial evaluating efficacy and safety of a new ophthalmic viscosurgical device in patients undergoing cataract surgery.

Purpose: To evaluate the efficacy and safety of Bio-Hyalur LVD compared with Viscoat ophthalmic viscosurgical device (OVD) in patients undergoing routine cataract surgery.

Setting: 2 tertiary eyecare hospitals in Italy.

Design: Prospective randomized clinical trial.

Iatrogenic ophthalmic artery occlusion after platelet-rich plasma dermal filler documented with ultra-widefield imaging.

Purpose: To report a case of iatrogenic ophthalmic artery occlusion (OAO) secondary to platelet-rich plasma (PRP) dermal filler injection for facial rejuvenation documented with ultra-widefield imaging.

Methods: Case report.

Results: A 45-year-old woman developed a sudden and painful vision loss in the left eye (LE) after a dermal filler injection of PRP in the left glabellar region.

Combined photorefractive keratectomy and corneal collagen cross-linking for treatment of keratoconus: a 2-year follow-up study.

Background: Corneal collagen cross-linking (CXL) is considered an effective procedure for slowing down or eliminating the progression of keratoconus. New techniques, in combination with CXL, have been proposed to stop the evolution of keratoconus and improve the visual function.

Objective: To evaluate the effectiveness of combined photorefractive keratectomy (PRK) with mitomycin-C (MMC) application and CXL in the management of grade 1-2 keratoconus over a 2-year follow-up.

Classification Tree to Analyze Factors Connected with Post Operative Complications of Cataract Surgery in a Teaching Hospital.

Background: Artificial intelligence (AI) is becoming ever more frequently applied in medicine and, consequently, also in ophthalmology to improve both the quality of work for physicians and the quality of care for patients. The aim of this study is to use AI, in particular classification tree, for the evaluation of both ocular and systemic features involved in the onset of complications due to cataract surgery in a teaching hospital.

Methods: The charts of 1392 eyes of 1392 patients, with a mean age of 71.

Analysis of Corneal Distortion after Myopic PRK.

The purpose of the study is to evaluate the corneal biomechanical properties (CBP) and their behaviors after myopic refractive surgery both with Ocular Response Analyzer (ORA) and Corvis ST (CST). This retrospective study included 145 eyes of 145 patients with a mean age of 33.13 ± 9.

Three-Year Outcomes of Tri-Folded Endothelium-In Descemet Membrane Endothelial Keratoplasty With Pull-Through Technique.

Purpose: To assess the 3-year outcomes of tri-folded endothelium-in Descemet membrane endothelial keratoplasty (DMEK) using bimanual pull-through delivery technique.

Design: Interventional case series.

Methods: In this single-center study, we included 153 consecutive eyes that underwent DMEK for various indications (Fuchs endothelial corneal dystrophy [FECD]: n = 111; bullous keratopathy [BK]: n = 24; and failed graft: n = 18).

Standard, transepithelial and iontophoresis corneal cross-linking: clinical analysis of three surgical techniques.

Background: To evaluate the clinical results of standard, transepithelial (TE) and iontophoresis (I) corneal cross-linking (CXL), in patients with progressive keratoconus.

Methods: Thirty eyes of 30 patients with progressive keratoconus treated by CXL (10 by standard-CXL, 10 by TE-CXL and 10 by I-TE-CXL) with 12 months of follow-up. Pre- and postoperative ophthalmologic testing were: uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), refractive examination (spherical error, spherical equivalent), corneal topography (corneal astigmatism, simulated maximum, minimum and average keratometry), aberrometry (coma and spherical aberration), pachymetry and endothelial cell density.

Customized photorefractive keratectomy to correct high ametropia after penetrating keratoplasty: A pilot study.

Purpose: To evaluate preliminarily the safety and efficacy of customized photorefractive keratectomy (PRK) to correct ametropia and irregular astigmatism after penetrating keratoplasty (PK).

Methods: This pilot study included five eyes of five patients with a mean spherical equivalent of -5.1±1.

Feline perforating dermatitis resembling human reactive perforating collagenosis: clinicopathological findings and outcome in four cases.

The clinicopathological findings of perforating dermatitis in two young and two adult cats are described. In all cases, the lesions were characterized by single or multiple papules and plaques, 0.5-3.
