To ascertain whether death-to-preservation time (DPT) is associated with donor endothelial cell density (ECD), primary graft failure (PGF), and infection. Donor corneas aged older than 10 years with ECD 2000 to 4500 cells/mm2 were procured between 2011 and 2018 by a single eye bank. Donor corneas were analyzed retrospectively for the main outcome measures of PGF, infection, and ECD. Means and proportions of study parameters were compared between corneas with long and short DPT, defined as greater or less than 14 hours, respectively, excluding corneas with a history of intraocular surgery or diabetes. Multivariate analyses were performed using logistic regression, adjusting for donor age at time of death, history of diabetes mellitus, and history of cataract surgery. Among 12,015 corneas, those with long DPT had a statistically but not clinically significant higher ECD than that of corneas with short DPT (2754 vs. 2724 cells/mm2, P < 0.01). There was no difference in PGF and infections in corneas with long versus short DPT (0.28% vs. 0.26%, P = 0.86; 0.43% vs. 0.29%, P = 0.51, respectively). Longer DPT is not associated with a clinically meaningful reduction in donor ECD, PGF, or infection. Longer DPT is not associated with a clinically meaningful reduction in donor ECD, PGF, or infection. The purpose of this study was to report a surgical technique for closure of a traumatic corneal perforation in a patient with healthy endothelium. A 69-year-old male patient presented to Southend University Hospital with a 2.5 mm round temporal corneal perforation caused by a metallic foreign body from an industrial accident. Best-corrected visual acuity at presentation was 6/36. The patient received a tectonic small diameter Descemet stripping automated endothelial keratoplasty (mini-DSAEK) to close the perforation. The patient subsequently developed traumatic cataract and underwent cataract surgery 8 months later. Clinical outcomes at 1 week, 1 month, 3 months, 6 months, and 9 months were evaluated. The primary outcomes of interest were successful sustained closure of the perforation and surgical complications, with secondary outcomes of best-spectacle corrected visual acuity (BSCVA, Snellen) and keratometric astigmatism (KA, Pentacam). The anterior chamber was reformed by the graft, restoring the globe's mechanical integrity. The bare stroma reepithelized by 1 week. Neither intraoperative nor postoperative surgical complications were reported. The anterior chamber remained deep and formed during subsequent follow-ups through 9 months. At the 9-month follow-up, final best spectacle-corrected visual acuity was 6/6-1 (Snellen fraction). Keratometric astigmatism was 1.1 diopters. Tectonic mini-Descemet stripping automated endothelial keratoplasty is a safe technique in the management of corneal perforations too large for tissue adhesives, with a low astigmatic profile and rapid visual recovery.

To assess the effect of vectored thermal pulsation treatment for meibomian gland dysfunction on objective measures of lipid layer thickness (LLT) and tear osmolarity. One hundred patients with meibomian gland dysfunction diagnosis were recruited to participate. At their initial visit, baseline study parameters were recorded, and vectored thermal pulsation treatment was administered. XYL-1 chemical structure At the 2- to 3-month follow-up visit, the study parameters were reevaluated. Subjective symptoms were evaluated using the Ocular Surface Disease Index questionnaire. LLT was measured using an ocular surface interferometer. Tear osmolarity was calculated using impedance measurement of tear fluid collected from the eyelid marg
