Methods: Corneal wavefront measurements were performed in myopic and hyperopic eyes using a GALILEI Placido Dual Scheimpflug Analyzer…

Abstract Purpose: Orbital glands and drainage conduits are two distinct entities that constitute the lacrimal apparatus system, the malfunction of which leads to a range of ocular surface disorders. Despite the close functional relationship, how the two parts interact under pathophysiological conditions has not been directly tested. The study aims to investigate the lacrimal gland (LG)…

Abstract Purpose: To investigate the association of genetically determined primary open-angle glaucoma (POAG), myopic refractive error (RE), type 2 diabetes (T2D), blood pressure (BP), body mass index (BMI), cigarette smoking, and alcohol consumption with the risk of age-related cataract. Methods: To assess potential causal effects of clinical or behavioral factors on cataract risk, we conducted two-sample Mendelian…

Abstract Purpose: The purpose of this study was to describe the baseline refractive error, habitual accommodative tone (HAT) in Tibetan children and its longitudinal association with incident myopia and myopia progression. Methods: This was a prospective cohort study. From 7 elementary schools, 1440 children with mean age of 6.83 ± 0.46 years were included with full noncycloplegic…

Purpose The aim of this study was to introduce an optimized version of the Corvis Biomechanical Index for Chinese populations (cCBI). Design Retrospective, multicenter clinical validity enhancement study. Methods Patients were included from 7 clinics in Beijing, Shenyang, Guangzhou, Shanghai, Wenzhou, Chongqing, and Tianjin, China. Logistic regression was used to optimize the values of the…

Abstract Purpose: To describe the 3-dimensional (3D) location of the implantable collamer lens (ICL) quantitatively in the posterior ocular chamber of patients with myopia. Design: Cross-sectional study. Methods: To obtain visualization models before and after mydriasis, an automatic 3D imaging method based on swept-source optical coherence tomography was created. Parameters like the ICL lens volume (ILV), the tilt…

Abstract Importance: A bayesian network meta-analysis (NMA) can help compare the various types of multifocal and monofocal intraocular lenses (IOLs) used in clinical practice. Objective: To compare outcomes of presbyopia-correcting IOLs frequently recommended in clinical practice through a bayesian NMA based on a systematic review. Data sources: Medline (PubMed) and the Cochrane Central Register of Controlled Trials (CENTRAL)…
