Descemet membrane detachment (DMD) is a rare complication that occurs mainly after cataract surgery. We report the case of a 55-years-old woman who underwent refractive lensectomy. The Day-1 postoperative examination was unremarkable, the Day-7 examination showed corneal oedema related to DMD, which was confirmed by Visante(®) OCT. An intracameral injection of SF6 expansive gas allowed the reapplication of the membrane and the receding of corneal oedema. Through this observation, we discuss the pathogenesis of this uncommon entity and the contribution of Visante(®) OCT.

Purpose: Descemet membrane endothelial keratoplasty (DMEK) has emerged as a novel approach in corneal transplantation over the past two decades. This study aims to identify predisposing risk factors for post-DMEK ocular hypertension (OHT) and develop a preoperative predictive model for post-DMEK OHT.
Methods: Patients who underwent DMEK at Gangnam Severance Hospital between 2017 and 2024 were included in the study.

Purpose: This study aimed to evaluate the accuracy and quality of healing of main corneal incisions in femtosecond laser procedures in cataract surgery.
Methods: It was a prospective, non-randomized, investigator-masked study. A total of 37 eyes of 37 patients with indication for cataract surgery were separated into two groups in this prospective, nonrandomized study: Femto group, with incisions automated by femtosecond laser (18 eyes), and Phaco group, with incisions made using a keratome (19 eyes).

Purpose: To investigate the correlation between intracellular dark endothelial spots (IDESs) detected by specular microscopy and the incidence of graft failure after Descemet's membrane endothelial keratoplasty (DMEK).
Methods: We reviewed 100 consecutive DMEK patients performed by a single surgeon at two centres between January 2015 and July 2022. Central corneal thickness was evaluated using anterior segment optical coherence tomography (SS-1000; Tomey, Aichi, Japan), and endothelial cell density was measured using specular microscopy.

: The aim of this study was to evaluate the effect of a surgical technique for managing post-penetrating keratoplasty (PK) ectasia complicated by late endothelial failure (LEF). : A single-center pilot case series was conducted regarding consecutive patients affected by post-PK ectasia with late graft failure. Using a microkeratome, a single donor cornea was dissected to prepare a two-piece graft, comprising a larger anterior lamella made up of anterior stroma and a smaller posterior lamella made up of posterior stroma, Descemet's membrane, and endothelium.

Cell-instructive polymer hydrogels are instrumental in tissue engineering for regenerative therapies. Implementing defined and selective responsiveness to external stimuli is a persisting challenge that critically restricts their functionality. Addressing this challenge, this study introduces a versatile, modular hydrogel system composed of four-arm poly(ethylene glycol)(starPEG)-peptide and glycosaminoglycan(GAG)-maleimide conjugates.
