Ten years after keratoplasty: read the differences carefully
A retrospective Hong Kong cohort followed 74 eyes after DSEK/DSAEK or penetrating keratoplasty. The study reports long-term graft survival and visual outcomes.
Why it matters
Long follow-up is valuable, but apparent differences between procedures need to be read alongside baseline differences and statistical uncertainty.
Keep in mind
Small, non-randomised, historical cohort. The reported 10-year survival comparison was not statistically significant; this is not evidence about contemporary DMEK.
