Purpose: To report the outcomes of a Tenon patch graft (TPG) in sealing corneal perforations in cases with resolving infective keratitis.
Methods: This retrospective interventional study was conducted at a tertiary eye care center. All patients who underwent a TPG for corneal perforations because of clinically or/and microbiologically diagnosed infective keratitis between 2021 and 2023 were included. The surgical technique was consistent with that used in noninfective etiology. Out of 100 cases undergoing a TPG during the same period, 15 eyes of 14 patients had corneal perforations secondary to infective keratitis.
Results: The etiological profile included bacterial keratitis in 8, viral and fungal keratitis in 3, and Pythium keratitis in 1 eye of 15 eyes. One patient had bilateral infective keratitis after refractive surgery. The perforations were central in 7 and paracentral in 8 eyes. Successful restoration of tectonic integrity at 1 month was achieved in 14/15 eyes (93%). One patient had a repeat perforation at 3 weeks postoperatively, which was managed with a cyanoacrylate glue application. Infection control was achieved in all cases with adjunctive topical antimicrobial therapy.
Conclusions: A TPG is a viable option for restoring globe integrity in corneal perforations encountered in resolving infective keratitis.

In February 1968, NASA purchased 400 antigravity ballpoint pens from the Fisher Pen Company for the Apollo Program to prevent potential harm to astronauts and equipment. Mechanical pencils previously used in microgravity posed risks like eye injuries from floating fragments penetrating the cornea. The cornea is vulnerable to abrasions, perforations, and chemical burns in such environments, affecting crewmembers aboard the International Space Station (ISS).

We developed a two-stage manufacturing process utilizing cultivated autologous limbal epithelial cells (CALEC), the first xenobiotic-free, serum-free, antibiotic-free protocol developed in the United States, to treat blindness caused by unilateral limbal stem cell deficiency (LSCD) and conducted a single-center, single-arm, phase I/II clinical trial. Primary outcomes were feasibility (meeting release criteria) and safety (ocular infection, corneal perforation, or graft detachment). Participant eligibility included male or female participants age 18 to <90 years old and ability to provide written informed consent with LSCD.

Background: This case represents a rare presentation of bilateral corneoscleral perforation secondary to presumed ocular mycobacterium tuberculosis infection with the goal of reporting a case of bilateral corneoscleral perforation in the setting of a positive interferon-γ release assay (IGRA) test.
Findings: A 27-year-old patient presented with five months of redness, worsening eye pain, and five days of decreasing vision. Visual acuity (VA) was counting fingers bilaterally.

The purpose of this report is to present simultaneous bilateral penetrating keratoplasty (PK) in keratitis (AK). A 42-year-old male with keratoconus, wearing bilateral hybrid contact lenses, presented with pain in the left eye. He had a history of intrastromal corneal ring segment placement in the right and PK in the left eye.

Purpose: Corneal allograft survival is dramatically decreased in high-risk (HR) host beds. The purpose of this study was to investigate the outcome of HR keratoplasty (KP) in a single-center tertiary referral clinic and to determine risk factors for graft failure.
Methods: This retrospective study included adults referred for HR penetrating KP between 2014 and 2022.
