Purpose
To evaluate the effectiveness of repeat DALK in patients with prior unsuccessful DALK procedures.
Setting
Magrabi Health, Jeddah, Saudi Arabia
Methods
We retrospectively reviewed medical records of 3 patients who underwent repeat DALK due to initial surgery failure. We documented reasons for repeat surgery, time since initial surgery, and pre- and postoperative BCVA for each patient.
Results
The follow-up period ranged from 6 to 12 months after repeat DALK. The primary indication for DALK was keratoconus (n = 3). Repeat surgery was necessitated when the corrected distant visual acuity (CDVA) decreased below 20/200. The time elapsed since the initial surgery varied from 3 years to 15 years. Postoperatively, the CDVA improved from 20/120 to 20/25 in 2 patients and the last patient shows improvement to 20/40 following the repeat DALK. At the most recent examination, all Re-DALK grafts were clear. In Re-DALK, the bed dissection was facilitated due to weaker adhesions.
Conclusions
