Chronological Versus Non-chronological Phacoemulsification Training

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.

Treatment and study plan

Chronological phacoemulsification training

Procedure

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

Non-Chronological phacoemulsification training

Procedure

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

Primary outcomes

  1. Success rate

    Time frame: From enrollment till three months after the last surgery

Secondary outcomes

  1. Incidence of complications

    Time frame: From enrollment till 3 months after the last surgery
