Results and complications of surgeons-in-training learning bimanual microincision cataract surgery.

PURPOSE: To evaluate visual outcomes and complications of bimanual microincision cataract surgery performed by surgeons in training.

SETTING

Institute of Ophthalmology, University of Modena and Reggio Emilia, Modena, Italy.

DESIGN

Prospective case series.

METHODS

The corrected distance visual acuity (CDVA), astigmatism, corneal pachymetry, and endothelial cell count were evaluated before and 7 and 30 days after bimanual MICS performed by surgeons in training. Intraoperative and postoperative complications were also recorded.

RESULTS

Three surgeons in training performed bimanual MICS in 150 eyes of 131 patients. There were 18 intraoperative complications (12.0%) (10 iris traumas [6.6%]; 4 capsule ruptures without vitreous loss [2.7%]; 3 capsule ruptures with vitreous loss [2.0%]; 1 intraocular lens [IOL] implantation in the sulcus due to zonular laxity [0.7%]). There were 5 postoperative complications (3.3%) (2 iris prolapses [1.3%]; 1 IOL loop malposition [0.7%]; 1 narrowing of anterior chamber [0.7%]; 1 capsulorhexis phimosis [0.7%]). Thirty days postoperatively, the mean CDVA improvement was 0.53 ± 0.20 (Snellen decimal) (P < .05), the mean decrease in astigmatism was 0.09 ± 0.54 diopter (P = .29), and the mean increase in corneal pachymetry was 7.42 ± 22.01 μm (P = .12). There was statistically significant endothelial cell loss (mean 496.50 ± 469.66 cells/mm(2)) (P < .05).

CONCLUSIONS

Bimanual MICS performed by surgeons in training was safe and effective. Visual outcomes and complication rates were similar to those reported for coaxial cataract surgery performed by surgeons in training.
