A new surgical technique for endothelial keratoplasty is described, in which the composite of pre-Descemet's layer (Dua's layer) with Descemet's membrane and endothelium is transplanted subsequent to the removal of the recipient's Descemet's membrane. The technique was performed in five eyes of five patients, with successful attachment of the graft and good postoperative visual recovery in all cases. Postoperative optical coherence tomography showed good graft attachment without interface abnormalities and a mean graft thickness was 28±5.6 μm. This study demonstrates the practicality of the technique, termed pre-Descemet's endothelial keratoplasty (PDEK), which can be a viable option in endothelial keratoplasty with some potential advantages.

CACXL technique was effective and safe in performing cross-linking in corneas less than 400 μm after epithelial abrasion and appeared effective based on stromal demarcation line depth.

The COVID-19 pandemic has taken tragic proportions and has disrupted lives globally. In the wake of governmental lockdowns, ophthalmologists need practical and actionable guidelines based on advisories from national health departments on how to conduct their duties during nationwide lockdowns and after these are lifted. In this paper, we present a preferred practice pattern (PPP) based on consensus discussions between leading ophthalmologists and health care professionals in India including representatives from major governmental and private institutions as well as the All India Ophthalmological Society leadership. In this document, the expert panel clearly defines the range of activities for Indian ophthalmologists during the ongoing lockdown phase and precautions to be taken once the lockdown is lifted. Guidelines for triage, governmental guidelines for use of personal protective equipment from ophthalmologists' point of view, precautions to be taken in the OPD and operating room as well as care of various ophthalmic equipment have been described in detail. These guidelines will be applicable to all practice settings including tertiary institutions, corporate and group practices and individual eye clinics and should help Indian ophthalmologists in performing their professional responsibilities without being foci of disease transmission.
