Ab Externo Continuous Pressure Technique for DMEK in Vitrectomized Eyes: A Case Series

A case series of eight eyes from patients with an average age of 68±13 who underwent Descemet membrane endothelial keratoplasty (DMEK) surgery using a novel ab externo continuous pressure technique. The dataset, authored by figshare admin karger and last updated in May 2026, includes visual acuity outcomes assessed preoperatively and at one-year follow-up, with complication tracking up to seven years post-operation. Data was analyzed using a student's t-test.

Use Cases

• Analyzing the efficacy of a novel surgical technique based on the described continuous external pressure method.
• Studying visual acuity outcomes and complication rates in DMEK surgery based on the reported logMAR scores and re-bubbling events.
• Comparing surgical techniques for vitrectomized eyes based on the described challenges of graft unfolding and centration.
• Evaluating long-term graft survival based on the reported follow-up period of up to seven years.

Strengths

• Includes longitudinal data with follow-up tracking up to seven years post-operation.
• Reports specific quantitative outcomes, including best corrected visual acuity improvement from logMAR 1.05±0.12 to 0.3±0.16 (p=0.003).
• Describes a complete case series of eight eyes with an average patient age of 68±13.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
