A novel simulation model (without using human corneas) has been described for understanding the surgical concepts and developing tactile reflexes of Descemet membrane (DM) endothelium scroll manipulation and orientation in the anterior chamber, which are necessary for performing Descemet membrane endothelial keratoplasty (DMEK). Termed the "DMEK aquarium," this model helps facilitate the understanding of different maneuvers of the DM graft needed inside the fluid-filled anterior chamber, like unrolling or unfolding, flipping or inversion, and checking orientation and centration in the host cornea. A stepwise plan for surgeons starting to learn DMEK utilizing various available resources is also suggested.

A simple approach for transplanting Bowman layer and anterior stroma Bowman-stromal inlay (BSI) in keratoconic patients as an intervention to cease progression of ectasia and increase the overall thickness is described. A femtosecond laser was used to create BSI from human eye bank donor corneas and form an intrastromal pocket in the host cornea. The inlay was placed in the intrastromal space using an intraocular lens injector.

Methods: Retrospective analysis of medical records of eyes with CHED that underwent DMEK between January 1, 2018, and April 30, 2019, and had a minimum of 1-year follow-up.
Results: Three eyes of 2 CHED patients (a 10-year-old girl and a 22-year-old man) were included.
Purpose: To compare incision size enlargement at different times of cataract surgery and visual outcomes after surgery in 2 different intraocular lens (IOL) delivery systems (Vivinex iSert and UltraSert Preloaded IOL Delivery System).
Setting: Tertiary care eye institution.
Design: Prospective nonrandomized comparison study.
