Efficacy and comfort following the implantation of extended depth of focus, multifocal, and monofocal intraocular lenses in cataract patients.

Background: Extended depth of focus (EDOF) and multifocal (Multi) intraocular lenses (IOL) can provide a fixed distance of near vision, which may result in some discomfort for patients who prefer different near distances. The aim of this study was to compare the vision, comfortable near distance (CND) and visual comfort in patients who underwent implantation of EDOF, Multi, and monofocal (Mono) IOLs.

Methods: A total of 100 eyes were implanted with Tecnis ZXR00, ZMB00 or ZCB00 IOLs.

Diabetic uveopathy.

Diabetes can involve several ocular structures -- including the cornea, lens, and retina -- and cause vascular and neural changes in these tissues. Although retinopathy is the most common ocular complication of diabetes, uveopathy can also be observed. This includes vascular, neural, muscular, and basement membrane changes.

Concentrations of glucose metabolites in the aqueous humour of diabetic cataract eyes.

Purpose: Glucose metabolism underpins diabetic cataracts (DCs), but the relationship between the two remains unclear. Here, we tested the aqueous humour (AH) of patients with DCs to elucidate glucose metabolite levels.

Methods: In this study, aqueous humour (AH) samples were collected preoperatively from DC eyes (n = 37) and age-related cataract eyes (n = 37) from 74 patients (74 eyes) undergoing uncomplicated cataract surgery.
