How does poor depth perception affect FLS task performance?

• A. It leads to misjudgment of tissue depth and distance, increasing errors in dissection and suturing
• B. It improves depth judgment
• C. It has no effect
• D. It only affects camera focus

Answer: (A)

Depth perception is crucial for precise spatial judgments in FLS tasks. Because laparoscopic images are displayed in 2D, natural depth cues are reduced, so poor depth perception makes tissue depth and the distance to targets harder to gauge. That leads to errors in how deep you cut or dissect and how you place sutures, resulting in less accurate tissue handling and knotting. The idea that depth judgment would improve with poorer depth perception isn’t correct, and the impact isn’t limited to camera focus—depth misjudgment disrupts core task accuracy and efficiency in dissection and suturing.
