Atypical mycobacterial infections of the cornea can present with nonspecific inflammatory changes and graft rejection, with no obvious focus to culture and a subsequent delay to diagnosis. These pathogens are well documented in the literature following laser-assisted keratomileusis but have rarely been described following corneal transplant surgery. We report a single case of keratitis 1 year after tectonic keratoplasty.

Globally there is a shortage of available donor corneas with only 1 cornea available for every 70 needed. A large limitation to corneal transplant surgery is access to quality donor tissue due to inadequate eye donation services and infrastructure in many countries, compounded by the fact that there are few available long-term storage solutions for effectively preserving spare donor corneas collected in countries with a surplus. In this study, we describe a novel technology termed low-temperature vacuum evaporation (LTVE) that can effectively dry-preserve surplus donor corneal tissue, allowing it to be stored for approximately 5 years, shipped at room temperature, and stored on hospital shelves before rehydration prior to ophthalmic surgery.

Purpose: To report a rare case of conjunctival neuroma after a successful corneal neurotization surgery.
Methods: The clinical file and histopathology slides of this patient who underwent surgical corneal neurotization for a neurotrophic keratopathy in the right eye were reviewed.
Results: A 70-year-old man with a history of severe herpetic (varicella zoster) neurotrophic keratopathy and keratouveitis in the right eye developed a corneal perforation, which required tectonic keratoplasty (May 2020).

is a more prevalent cause of corneal ulcers in developing countries than in developed countries. We report five cases of corneal ulcers attributed to this organism with a literature review on bacterial cornea ulcers. Among the patients, four had underlying systemic illnesses while one was otherwise healthy.

Purpose: This study aimed to report the clinical characteristics, surgical indications, outcomes and long-term complications of full-thickness or lamellar corneal patch grafts for various indications.
Material-method: This retrospective study included 48 eyes of 47 patients who underwent full-thickness or lamellar corneal patch keratoplasty for treatment of corneal perforation, melting and descemetocele. Patient demographics, preoperative features, best-corrected visual acuity before and after surgery, mean follow-up time, corneal graft type, long-term complications, need for additional surgery, and anatomical success were analyzed.

Purpose: To describe the treatments used in cases of infectious keratitis and determine the risk factors associated with treatment failure, including prolonged infection duration, treatment modifications, and the need for surgical intervention.
Patients And Methods: This retrospective case series includes culture-proven microbial keratitis cases treated in nine hospitals in the region of Galicia, Spain, between 2010 and 2020.
Results: A total of 654 patients were included.
