Abstract

Purpose : This study aims to compare the outcomes of and incidence of complications in phacoemulsification surgeries performed by second-, third-, and fourth-year residents

Methods : A retrospective study considered 424 consecutive resident-performed phacoemulsification surgeries from Jun - Nov 2016. The surgeries were performed by ophthalmology residents from the University of Campinas (UNICAMP) in Brazil, who were guided by a senior surgeon. The study included surgeries performed by 10 second-year residents (R2 group), 9 third-year residents (R3 group), and 5 fourth-year residents (R4 group) and evaluated best-corrected visual acuity(BCVA) before surgery, intra- and postoperative complications, final BCVA(on the 30th postoperative day), and endothelial parameters based on specular microscopy and pachymetry results before surgery and on the 60th postoperative day

Results : There were 80 surgeries in the R2 group, 142 surgeries in the R3 group, and 202 surgeries in the R4 group. Mean age of R2 patients was 70.3 ±7.5 years old (range of 50 – 85 years), mean age of R3 patients was 66.9 ±9.2 years old (26 – 85 years); and mean age of R4 patients was 67.0 ±12.0 years old (26 – 91 years). Average BCVA before surgery was 0.26 ±0.18. A total of 50 intra-operative complications occurred (11.79% of all surgeries): there were 17(21.25%) in the R2 group, 22(15.49%) in the R3 group, and 11(5.45%) in the R4 group. Complications included 31 cases of posterior capsule tears, 19 cases of vitreous loss, 2 cases of nuclear loss into the vitreous cavity, 6 cases of aphakia, 2 wound burns, 4 cases of zonular dialysis, 4 cases of Descemet’s membrane detachment, and 9 iris lesions. Long-term monitoring revealed no endophthalmitis and 2 cases of bullous keratopathy (1 in the R2 group and 1 in the R3 group). Final BCVA exhibited statistically significant improvement (p=0.001). When preoperative specular microscopy results were compared to those of the 60th postoperative day, no statistical differences were found in most of parameters tested (p=0.28 in the case of endothelium density and p=0.30 for the percentage of hexagonal cells), with the exception of the coefficient of variation (p=0.03). Likewise, pachymetry results did not differ significantly(p=0.08)

Conclusions : Despite the learning curve, surgical phacoemulsification performed by surgeons in training resulted in low rates of complication and good visual outcomes
