Brief summary

The goal of this clinical trial is to compare between two methods used in training residents on phacoemulsification. The residents were classified into two groups; the first group were trained on surgical steps in a chronological order, while the second groups in non-chronological order. The outcomes included surgical competency, success rate and incidence of complications.

Interventions

PROCEDUREChronological phacoemulsification training

Residents trained step-by-step in the natural order of phacoemulsification (incision, capsulorhexis, hydrodissection, phacoemulsification, irrigation/aspiration, IOL implantation, wound closure).

PROCEDURENon-Chronological phacoemulsification training

Residents trained initially on selected steps (e.g., wound construction, IOL implantation, cortical cleanup) before progressing to more critical steps such as capsulorhexis and phacoemulsification
