Purpose: The aim of this study was to evaluate Viscoll collagen membrane (VCM) for lamellar keratoplasty.
Methods: A 54-year-old man with grade 4 recurrent pterygium underwent lamellar keratoplasty using VCM as the graft material. Standard keratoplasty postoperative treatments, including topical antibiotic-corticosteroid and artificial tears, were administered.
Results: Complete graft epithelialization was achieved after 4 days of the surgery. Follow-up at 9 months showed no pterygium recurrence as well as good integration of the VCM graft into the surrounding tissues with preserved transparency.
Conclusions: This case demonstrated that VCM possesses great potential as an alternative to the human donor cornea for lamellar keratoplasty; however, the application of VCM for lamellar keratoplasty still needs additional evaluation.

Preparation for cataract surgery in patients with keratoconus (KC) is associated with particular challenges: calculating the optical power of the intraocular lens (IOL), selecting the appropriate IOL model, and considering additional interventions aimed at stabilizing KC and reducing irregular astigmatism. This article presents a fundamentally new approach to combined treatment of KC with cataract, consisting of two stages: first, performing bandage therapeutic-optical keratoplasty (BTOK), followed by cataract phacoemulsification as the second stage.

The cornea, the anterior meniscus-shaped transparent and refractive structure of the eyeball, is the first mechanical barrier of the eye. Its functionality heavily relies on the health of its endothelium, its most posterior layer. The treatment of corneal endothelial cells (CECs) deficiency is allogeneic corneal graft using stored donor corneas.

Purpose: This study aims to evaluate the efficacy of various tomographic indices, both established and novel, in predicting endothelial decompensation leading to either spontaneous corneal transplantation or transplantation following cataract surgery in patients with Fuchs endothelial corneal dystrophy (FECD).
Methods: In this cross-sectional, retrospective study, we reviewed the files of 93 eyes from 54 FECD patients undergoing regular follow-up. We recorded clinical metrics such as morning visual disturbance (MVD) and corrected distance visual acuity.

The scope of eye banking activities has been expanding with the advances and techniques of keratoplasty. With the popularity of descemet membrane endothelial keratoplasty (DMEK) in the recent decade, there is a need to adopt the preparation of DMEK tissues in the eye banks. This necessitated surgical training of the eye bank technicians, development of infrastructure in the eye bank, innovative methods of graft preparation, and delivery for the surgery at distant surgery centers.

A male patient in his 20s, suffering from a persistent, infection-related corneal endothelial plaque (EP) was urgently referred to our tertiary medical centre for therapeutic penetrating keratoplasty (TPK). Over the preceding month, he had been undergoing treatment with both topical and oral antifungal medications due to clinical suspicion of fungal keratitis. At our centre, an endothelial scraping was performed using a reverse Sinskey hook to obtain samples for microbiology and revealed septate branching fungal hyphae.
