Abstract

Objectives: To evaluate the long-term visual outcomes of  Descemet's stripping automated endothelial keratoplasty sutureless small incision (DSAEK_SI) at the Vietnam National Eye Hospital from January 2018 to December 2020. Subjects and Methods: A cross-sectional and retrospective study was conducted on the medical records of 30 eyes that underwent DSAEK sutureless small incision  between January 2018 and December 2020. Results: The mean follow-up time was 60.56 ± 10.04 months. Preoperatively, 26/30 eyes (86.6%) were classified as blind (VA less than count finger at 3 meters). This number decreased to 21/30 eyes (70%) at hospital discharge and  reduced to 9/30 eyes (30%) at Present. The number of eyes with vision better than the blindness threshold increased from 4/30 (13.3%) preoperatively to 9/30 (30%) at hospital discharge, and obtain 70% at present. The highest of best-corrected visual acuity (BCVA) at the present is 20/40. Mild astigmatism (0.25-2.00D) was 11/30 eyes (36,6%) at 1 month after hospital discharge and increased to 21/26 eyes (80.7%) at present. Moderate astigmatism (2.00-3.00D) decreased from 13/30 eyes (43,3) to 4/26 eyes (15,3%). High astigmatism in 6/30 eyes (20%) decreased to 1/26 eyes (3,8%). The visual quality was significantly higher compared to conventional DSAEK (p<0,05). Conclusion: Visual acuity improved shortly after surgery of DSAEK-SI and keep increasing and stabilize at the long term of follow-up. The visual quality was significantly higher compared to conventional DSAEK.
