Patients who underwent either bimanual 1.7-mm microincision cataract surgery or coaxial 1.8-mm microincision cataract surgery showed satisfactory results, with some endothelial cell loss and good visual acuity with both techniques, a study found.
"The visual results were excellent in both groups," researchers said. "Both MICS techniques enabled preservation of corneal endothelial cells equally well and were similar in terms of minor surgical trauma and the influence of surgery on corneal endothelial cell density. Our results support the use of both MICS techniques for cataract surgery."
The nonrandomized prospective consecutive series was composed of two groups of patients: 51 eyes of 51 patients underwent coaxial 1.8-mm MICS, and 50 eyes of 50 patients underwent bimanual 1.7-mm MICS.
Mean follow-up in the study was 22.58 days.
The study authors found that endothelial cell density had a significant decrease in both incision groups: 9.46% in the 1.8-mm group and 9.27% in the 1.7-mm group.
Preoperatively, mean corrected distance visual acuity was 0.36 in the 1.8-mm group and 0.30 in the 1.7-mm group. Postoperatively, both groups had a mean corrected distance visual acuity of 0.95.
