PURPOSE: To characterize vision-related quality of life following penetrating keratoplasty (PKP), deep anterior lamellar keratoplasty (DALK), Descemet stripping automated endothelial keratoplasty (DSAEK), and Descemet membrane endothelial keratoplasty (DMEK) using the National Eye Institute Visual Function Questionnaire (NEI-VFQ 9). METHODS: Using the Sight Outcomes Research Collaborative (SOURCE) ophthalmology electronic health record repository, questionnaire responses were obtained from 103 PKP patients, 24 DALK patients, 42 DSAEK patients, and 50 DMEK patients undergoing postoperative examination. No exclusions were made based on preoperative diagnosis, age, complications, or comorbidities. Associations between clinical characteristics and vision-related quality of life were analyzed using nonparametric and linear regression methods. RESULTS: Patients were surveyed an average of 1.5 years postoperatively (range 24 days – 4.4 years). Participants who had undergone DALK, DMEK, DSAEK, and PKP had median composite VFQ scores of 77.8, 84.2, 76.1, and 70.6 respectively (p= 0.002). There were no significant differences in VFQ scores between patients treated with DMEK versus DSAEK (p=0.440) or between patients treated with PKP versus DALK (p=1.000). Higher postoperative acuities in the operative and fellow eyes were associated with higher VFQ scores (p
