Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A

Group Type ACTIVE_COMPARATOR

Chronological phacoemulsification training

Intervention Type PROCEDURE

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

Group B

Group Type ACTIVE_COMPARATOR

Non-Chronological phacoemulsification training

Intervention Type 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
