The study included 977 DMEK surgeries (942 with older donor tissue [≥50 years old] and 35 with younger tissue [28–49 years old]). There was no statistically significant difference between younger and older donor tissue when comparing unscrolling time, mean endothelial cell loss at 6 months, and rebubble rate (though the rebubble rate was lower in the younger group). Dr. Gupta said that while she won't neces- sarily be asking for younger donor tissue, this study can provide confidence in the tissue if it is ever more available. The impact of epithelial basement membrane dystrophy and Salzmann's nodular degeneration on biometry measurements Mark Goerlitz-Jessen, MD, Preeya Gupta, MD, Terry Kim, MD T he Best of ASCRS 2019 is a general session at the ASCRS ASOA Annual Meeting where members of the EyeWorld Editorial Board select what they think were the best papers in different categories from the meeting. They choose from the papers that were awarded Best Paper of Session in each individual paper session throughout the meet- ing and explain why they made their selections. Here we recap what those papers were in the Cornea category and why Preeya Gupta, MD, a member of the EyeWorld Cornea Editorial Board, thought they were noteworthy. Visible meibomian gland structure increases after vectored thermal pulsation treatment in dry-eye patients with meibomian gland dysfunction Arjan Hura, MD, Alice Epitropoulos, MD, Craig Czyz, DO, Caroline Blackie Dr. Gupta introduced her first paper under the topic of meibomian gland dysfunction (MGD), setting the stage that gland atrophy occurs with chronic MGD and noting the assumption that gland atrophy is permanent. This paper challenges that assumption, Dr. Gupta said. This retrospective observational study in- volved 102 patients who were treated with vec- tored thermal pulsation and 32 who had only serial dynamic meibomian imaging and dry eye evaluations, serving as controls. At least a year after treatment, 70% in the experimental group showed improved visible gland structure, while 71% of those who did not have thermal pulsa- tion showed worsening visible gland structure. "I think as more and more people are getting meibography in their patients, we should have a framework to assess it, and if we're help- ing to regenerate glands, to study that further," Dr. Gupta said.
