PURPOSE: To determine whether a structured biometry course improves refractive outcomes of resident phacoemulsification.
SETTING: Northeast Veterans Administration Hospital, Northport, New York, USA.
DESIGN: Retrospective case study.
METHODS: Phacoemulsification surgeries performed by residents before and after a biometry curriculum were reviewed. The inclusion criterion was phacoemulsification performed by residents. Patients with fewer than 3 months of follow-up were excluded. The main outcome measure-the mean absolute difference between the target and final refraction-was compared using a linear mixed model.
RESULTS: Phacoemulsification surgeries performed by 4 residents before (n = 223) and by 4 residents after (n = 242) a biometry curriculum was implemented were reviewed. All measured preoperative factors were similar in both groups, including age, visual acuity, axial length, steep and flat keratometry values, astigmatism, anterior chamber depth, and lens thickness. Before the biometry course was instituted, 10% of patients had a mean absolute difference of less than 0.25 diopter (D); the percentage was 35% afterward. The mean absolute difference was less than 0.50 D in 40% before the curriculum was initiated and 70% after. The mean absolute difference was less than 1.00 D in 75% before the curriculum was initiated versus 94% after (all P < .05). The corrected distance visual acuities were similar in both groups, with 83% and 80%, respectively, having an acuity of at least 20/25 (P > .05).
CONCLUSION: Residents' refractive predictions significantly improved after a formal biometry curriculum, showing that improvements in resident surgical outcomes are possible with structured curriculums reinforcing outcome measures.
