Purpose: To report a penetrating corneal transplant in which there was inadvertent inversion of the corneal button.
Design: Interventional case report.
Methods: A 48-year-old man with lattice corneal dystrophy had a third penetrating keratoplasty in the right eye 3 years after the second procedure and 2 years following renal transplantation.
Results: Histologic examination of the corneal button from the second penetrating keratoplasty disclosed inadvertent corneal graft inversion. Survival epithelium from the donor in the anterior chamber may be explained by the ocular anterior chamber-associated immune deviation or by the patient's systemic cyclosporine A (CsA) treatment after renal transplantation.
Conclusions: Histologically proven corneal button inversion is a rare cause of corneal graft failure.

Intraocular pressure (IOP) readings using three different methods (Goldmann applanation tonometry (GAT), Corvis ST, and iCare) were compared in patients who underwent penetrating keratoplasty (PK). : An observational cross-sectional study with prospective recruitment of patients was conducted. IOP measurements were acquired using GAT, iCare, and Corvis (including both uncorrected IOP (CVS-IOP) and biomechanical IOP (bIOP)), and the agreement among methods was analyzed using Bland-Altman plots.

The need for better and simpler alternative crosslinking strategies to treat keratoconus (KC) is becoming essential as there is only a single approved way to treat it. Recently, conventional UV-A Riboflavin crosslinking is proven to have some disadvantages such as causing damage to the corneal endothelium and inducing keratocyte apoptosis. A chemical cross-linker (CXL) using carbodiimide chemistry and an octanedioic acid spacer is found effective in stiffening the cornea and has the potential to be developed as an alternative therapy to halt KC progression.

Background: Corneal pathologies are among the most common reversible sight-threatening diseases globally. As such, corneal tissue transplantation (keratoplasty) techniques are evolving over time depending on the prevalence of different pathologies in each geographical area. We aim to provide a baseline information on the common keratoplasty procedures performed in our area in relation to prevalent corneal pathologies and to analyze common corneal surgical practice trends in our area.

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).
