Deep Learning-Based Estimation of Implantable Collamer Lens Vault Using Optical Coherence Tomography.

Purpose: To develop and validate a deep learning neural network for automated measurement of implantable collamer lens (ICL) vault using anterior segment optical coherence tomography (AS-OCT).

Design: Cross-sectional retrospective study.

Methods: A total of 2647 AS-OCT scans were used from 139 eyes of 82 subjects who underwent ICL surgery in 3 different centers.

Efficacy of progressive thickness intrastromal corneal ring segments in the treatment of duck phenotype keratoconus.

Purpose: To evaluate clinical outcomes in patients with asymmetric duck phenotype keratoconus implanted with asymmetric progressive thickness intrastromal corneal ring segments (PT-ICRS, Keraring AS, Mediphacos, Belo Horizonte, Brazil), and to demonstrate improved visual acuity and symmetry in corneal flattening.

Methods: This single-center, retrospective, observational study evaluated the clinical outcomes at 1, 3, and 6 months after implantation of PT-ICRS in patients with duck phenotype keratoconus. After creating the intrastromal tunnel with a femtosecond laser, one 160-degree arc length PT-ICRS, either 150/250 µm or 200/300 µm, was implanted.

Clinical outcomes of laser in situ keratomileusis with an aberration-neutral profile centered on the corneal vertex comparing vector planning with manifest refraction planning for the treatment of myopic astigmatism.

Purpose: To evaluate clinical outcomes of laser in situ keratomileusis (LASIK) with an aberration-neutral profile centered on the estimated visual axis (considering 70% of the pupil offset toward the corneal vertex) comparing vector planning with manifest refraction planning for the treatment of myopic astigmatism.

Setting: Muscat Eye Laser Center, Muscat, Sultanate of Oman, Muscat, Oman.

Design: Retrospective case series.

Immunologic Rejection Episodes After Deep Anterior Lamellar Keratoplasty: Incidence and Risk Factors.

Purpose: To assess the rejection episode rate after deep anterior lamellar keratoplasty (DALK) and to identify associated risk factors.

Methods: This retrospective review of 251 primary DALK procedures performed by 14 surgeons at a single center between February 2008 and November 2015 evaluated the rejection episode rate and associated risk factors using Kaplan-Meier survival and proportional hazards analyses, which took the length of follow-up into consideration.

Results: Transplant indications were keratoconus or ectasia after laser refractive surgery (n = 170, 68%), corneal opacity (n = 72, 28%), and other anterior corneal disease (n = 9, 4%).

A year of cornea in review: 2013.

Purpose: The goal of this study was to provide an update of significant corneal literature published in 2013.

Design: This study is a systematic literature review.

Methods: We conducted a systematic review of the English-language literature published from January 1, 2013, to December 31, 2013, using the following PubMed search and Medical Subject Headings terms: cornea transplantation, keratoplasty, Descemet membrane endothelial keratoplasty, Descemet stripping endothelial keratoplasty, cross linking, pre-Descemet's layer, Rho-associated kinase, keratoprosthesis, infectious keratitis, corneal dystrophy, corneal astigmatism, and keratoconus.

Long-term follow-up and complications of stripping descemet membrane without placement of graft in eyes with Fuchs endothelial dystrophy.

Purpose: The aim of this study was to describe the clinical course in Fuchs dystrophy where the central Descemet membrane was removed and not replaced with donor tissue.

Methods: Three patients with Fuchs endothelial dystrophy had descemetorhexis without endothelial keratoplasty.

Results: In each case, endothelial cells repopulated the majority of the descemetorhexis area within about 4 months, but 1 localized area failed to repopulate, which led to persistent focal edema and associated symptoms.

Sjögren's syndrome at the crossroad of polyautoimmunity.

The coexistence of autoimmune diseases (i.e., polyautoimmunity) in Sjögren's syndrome (SS) was investigated in a cross-sectional study involving 410 patients.
