Surgeon Preference for Endothelial Keratoplasty Techniques.

PURPOSE To examine barriers and facilitators to adoption of Descemet membrane endothelial keratoplasty (DMEK) for treatment of endothelial dysfunction. METHODS Anonymous electronic surveys were emailed to surgeons ordering corneal transplant tissue in the past 18 months from 2 eye banks in the United States (US). RESULTS Of 365 surgeons emailed, 118 (32%) completed the survey. Most respondents were located at an urban site (59%), were in private practice (64%), and had been in practice for >10 years (53%). Participants performing DMEK (n = 70) were more likely to have been in practice for ≤10 years than those not performing DMEK (56% vs. 35%, respectively, P = 0.03). Among respondents not performing DMEK (n = 48, 41%), the most frequently reported barriers were technical difficulty (n = 30, 63%), a lack of experience (n = 29, 60%), low surgical volume (n = 20, 42%), and risk of postoperative complications (n = 19, 40%). Most (n = 46, 96%) respondents not performing DMEK were interested in doing so, with the following reported as helpful resources: wet laboratory courses (n = 35, 73%), eye bank-prepared tissue: preloaded/prestripped (n = 32, 67%), back-up tissue in case of inadvertent graft damage (n = 29, 60%), higher surgical volume to support the learning curve (n = 28, 58%), and surgical mentorship (n = 22, 46%). Only a minority wanted more data to highlight superiority over other EK procedures (n = 12, 25%). CONCLUSIONS There is substantial interest in learning to perform DMEK among the surgical community. Barriers identified in this survey may be addressed to help surgeons increase DMEK adoption.
