Purpose

To compare corneal densitometry (CD) following uneventful Descemet membrane endothelial keratoplasty (DMEK) with healthy corneas throughout  5 years follow up.

Setting

To compare corneal densitometry (CD) following uneventful Descemet membrane endothelial keratoplasty (DMEK) with healthy corneas throughout  5 years follow up.

Methods

Medical records of 212 consecutive surgeries were reviewed. Sixty cases without intraoperative and postoperative complications were included (group 1). Scheimpflug CD of the 0- to 2-mm zone, 2- to 6-mm and 6- to 10-mm annulus were evaluated preoperatively and at 3, 6, 12, 24, and 60 months postoperatively. All  results were compared with an age matched group of uncomplicated pseudophakic eyes (group 2; n =20) and a group of healthy, young subjects (group 3; n = 30).

Results

Total CD at 0 to 2 mm was 33 ± 10 grayscale units (GSU) preoperatively and decreased to 21.8 ± 3.1 GSU at 60 months (p <0.001), being significantly higher compared with both control groups (p ≤ 0.043). Total CD at 2 to 6 mm was 27.8 ± 8 GSU preoperatively and decreased to 22.2 ± 4.2 GSU at 60 months (p <0.001), showing  statistically significant difference compared with both groups (p ≤ 0.016). Total CD at 6 to 10 mm was 30 ± 8.3 GSU preoperatively and increased to 34.6 ± 7.8 GSU at 60 months (p <0.001), showing  no statistically significant difference compared with group 1 (p ≥ 0.093). 

Conclusion

Total CD at 0 to 2 mm was 33 ± 10 grayscale units (GSU) preoperatively and decreased to 21.8 ± 3.1 GSU at 60 months (p <0.001), being significantly higher compared with both control groups (p ≤ 0.043). Total CD at 2 to 6 mm was 27.8 ± 8 GSU preoperatively and decreased to 22.2 ± 4.2 GSU at 60 months (p <0.001), showing  statistically significant difference compared with both groups (p ≤ 0.016). Total CD at 6 to 10 mm was 30 ± 8.3 GSU preoperatively and increased to 34.6 ± 7.8 GSU at 60 months (p <0.001), showing  no statistically significant difference compared with group 1 (p ≥ 0.093).
