Quantitative Analysis of Instrument Motion Paths in Cataract Surgery across a Resident's Training.

ABSTRACT:

Purpose

To objectively quantify the motion paths of surgical instruments during cataract surgery across a resident's training, identifying patterns of skill acquisition and proficiency development.

Design

An n = 1 panel study.

Subjects

One ophthalmology resident performing cataract surgery.

Methods

One hundred cataract surgery videos performed by a single resident from their sixth to 760th case were collected. Advanced motion tracking software (Computer Vision Annotation Tool) was utilized to annotate and track the trajectories of 11 surgical instruments on a frame-by-frame basis. Monotonic trends were assessed using the Mann-Kendall test and Theil-Sen slope estimation, with Spearman correlation measuring the association between case number and performan
