Aim: To investigate the efficacy of systemic mycophenolate mofetil (MMF) as an adjunct in combination with topical tacrolimus (FK506) and corticosteroid eyedrops for preventing corneal graft rejection after high-risk keratoplasty (HRK).

Methods: In this cohort study, 55 consecutive patients (55 eyes) from an eye center who met the criteria of HRK were included. The definition for HRK includes large grafts of no less than 9 mm diameter, vascularized cornea of two or more quadrants, regrafting, or eccentric grafts.

Corneal Graft Rejection: Is it Reflected in Peripheral Immune Cells? Results of a Prospective Multicenter Study (VISICORT).

Background: Allogeneic graft rejection is the leading cause of graft failure in corneal transplantation (CT) despite the immune privilege of the anterior chamber and corneal bed. The ability to identify patients at higher risk of acute rejection before or after CT could have a major impact on the clinical management of these patients.

Methods: To address this important issue, a multicenter European cohort of low-risk (n = 142) and high-risk (n = 102) CT recipients was established, and the immune system was evaluated in detail in peripheral blood mononuclear cells and plasma before and 6 and 12 mo posttransplantation.

Outcomes of staged conjunctival flap and corneal transplantation for infectious keratitis resistant to medical treatment.

Background/aims: To explore the outcomes of conjunctival flap (CF) followed by keratoplasty in patients with severe infectious keratitis (IK) unresponsive to medical treatment.

Methods: This is a retrospective monocentric study including 29 eyes of 29 patients with IK resistant to antibiotic treatment associated with stromal ulcer deepening to ≥50% of corneal thickness. All eyes underwent Gundersen's CF procedure and penetrating keratoplasty (PK), deep anterior lamellar keratoplasty (DALK) or mushroom keratoplasty (MK), at least 4 months thereafter.

Machine learning methods to identify risk factors for corneal graft rejection in keratoconus.

Machine learning can be used to identify risk factors associated with graft rejection after corneal transplantation for keratoconus. The study included all keratoconus eyes that underwent primary corneal transplantation from 1994 to 2021. Data relating to the recipient, donor, surgery, and postoperative course that might be associated with the occurrence of a graft rejection reaction were compiled.

Khodadoust Line Indicating Graft Rejection in Descemet's Stripping Automated Endothelial Keratoplasty: A Unique Case Report.

Purpose: To highlight the rarity of the endothelial rejection line, also known as the Khodadoust line, as a manifestation following Descemet's stripping automated endothelial keratoplasty (DSAEK). The objective is to present a meticulously detailed case, including imaging and anterior optical coherence tomography (OCT), to enhance understanding and recognition of this phenomenon.

Methods: A detailed case presentation involving a 50-year-old male, 3 years post-DSAEK transplantation for endothelial damage resulting from intraocular surgeries.

Comparison of clinical outcomes, complications and patient satisfaction following deep anterior lamellar keratoplasty and penetrating keratoplasty.

Background: Keratoplasty is a surgical procedure in which a damaged or diseased cornea is replaced with healthy donor tissue, thereby restoring vision. Recent advancements have led to the replacement of penetrating keratoplasty (PKP) with the more selective deep anterior lamellar keratoplasty (DALK) procedure, especially for treating keratoconus. Although DALK typically has a shorter recovery time, less pain and a lower risk of rejection, PKP is still being performed for more severe corneal diseases.

A Study of Clinico-Microbiological Profile and Treatment Outcomes of Infectious Keratitis.

Background  Infectious keratitis (IK) is one of the major causes of corneal blindness in developing and developed nations. Numerous infections, including bacterial, fungal, viral, and protozoa, have been linked to IK. Corneal perforations can happen as one of the complications of IK.

A novel sandwich technique of minimally invasive surgery for corneal perforation.

This study aimed to describe a novel sandwich technique of minimally invasive surgical implantation by using corneal stromal lenticules for corneal perforation. This prospective observational study included nine patients aged 23-79 years (mean, 54 ± 9) from Tianjin Eye Hospital. Corneal stromal lenticules with a central thickness of 120 μm were obtained from small incision lenticule extraction(SMILE).

Five years of emergency keratoplasty at a tertiary eye hospital.

Purpose: The aim of this study is to present the results of patients who underwent emergency keratoplasty for tectonic or therapeutic reasons.

Methods: Medical records of 33 patients who underwent tectonic or therapeutic keratoplasty at Ege University Department of Ophthalmology between January 2019 and January 2024 were retrospectively evaluated. Demographic characteristics, ocular and systemic findings, indications of keratoplasty, size of grafts, need for re-keratoplasty, preoperative treatment modalities, need for additional surgical interventions, and prognosis of the patients were investigated.

Induced pluripotent stem-cell-derived corneal epithelium for transplant surgery: a single-arm, open-label, first-in-human interventional study in Japan.

Background: The loss of corneal epithelial stem cells from the limbus at the edge of the cornea has severe consequences for vision, with the pathological manifestations of a limbal stem-cell deficiency (LSCD) difficult to treat. Here, to the best of our knowledge, we report the world's first use of corneal epithelial cell sheets derived from human induced pluripotent stem cells (iPSCs) to treat LSCD.

Methods: This non-randomised, single-arm, clinical study involved four eyes of four patients with LSCD at the Department of Ophthalmology, Osaka University Hospital.

Inhibiting corneal transplantation rejection via lymphatic vessel ligation in a novel murine model.

The lymphatic system is a crucial contributor to allograft rejection after corneal transplantation. However, no surgical procedures for the central pathway where conjunctival lymphatic vessels converge have been investigated. Therefore, we aimed to establish a murine model of lymphatic vessel ligation and evaluate its inhibitory effect on corneal allograft rejection.

Evaluation of the Cornea by Anterior Segment Optical Coherence Tomography in Diseases of the Cornea.

Aim: The aim of the study was to determine any new findings provided by anterior segment optical coherence tomography (AS-OCT) in different corneal diseases diagnosed by slit lamp examination (SLE).

Methods: This cross-sectional, observational, hospital-based study was conducted at a tertiary care centre in Western Maharashtra from September 2022 to June 2024, and it included 93 eyes of 93 patients with isolated corneal diseases. A detailed SLE of the anterior segment was done to assess corneal pathology, corneal thickness, corneal structural integrity, presence of corneal opacities, corneal vascularization, presence of other abnormalities like corneal degeneration, corneal foreign bodies, Kayser-Fleischer (KF) ring, ocular surface squamous neoplasia (OSSN).
