Purpose
To asses the one-year follow-up outcomes of Descemet Stripping Only (DSO) surgery in patients diagnosed with Fuchs Endothelial Corneal Dystrophy (FECD).
Setting
DSO has become one of the preferred surgical treatments for selected patients with FECD without evidence of peripheral guttae. In this procedure, a central area of 5 milimiters of Descemet membrane and endothelium is removed. The main advantage of this technique is that no donor endothelium is required.
Methods
A total of 26 patients diagnosed with FECD who underwent DSO surgery were prospectively enrolled. Preoperative measurements of decimal visual acuity (VA) and pachymetry, using CASIA2, were obtained. Postoperative follow-up visits were scheduled at day 1, weeks 1, 4, 8, 12, 16, 32 and 1 year after surgery. At each visit, VA and pachymetry measurements were recorded. The percentage of patients achieving corneal clearance, observed at the slit lamp examination, was also documented at each follow-up visit.
Results
The mean age of the patients was 64 ± 10 years. 5 were male (19.23%) and 21 were female (80.77%). The mean VA was 0.51 ± 0.2, and the mean pachymetry was 613.19 ± 66.8 microns. Of the surgeries performed, 18 (69.23%) were combined phacoemulsification with DSO, while 8 (30.77%) were DSO surgeries without associated phacoemulsification. The mean VA was 0.62 and 0.68 at weeks 8 and 12 post-surgery, respectively. By the one-year mark, the mean VA improved to 0.95 ± 0.2. Pachymetry was 606.96 ± 108.7 microns at week 8 and 572.04 ± 88.7 microns at week 12 post-surgery. By the one-year follow-up, pachymetry had decreased to 563.93 ± 27.2 microns. Corneal clearance was observed in 80.77% of patients at week 8, reaching 100% clearance by week 16.
Conclusions
DSO is an effective and predictable technique for the surgical treatment of FECD with healthy peripheral endothelium. The improvement in VA, pachymetry and corneal clearance after surgery should be between the second and third month, although cases of earlier recovery exist. A precise surgical technique is essential for achieving success.
