AI Technical Summary
The lack of a dedicated YAG laser posterior capsulotomy training device that can accurately simulate human eye anatomy and pupillary changes has resulted in poor training outcomes for doctors and high-risk clinical procedures.
A simulation training device was designed, comprising a transparent main body, a bionic eyeball, a pupil adjustment mechanism, and a posterior capsule replacement module. The device uses a mechanically adjustable aperture structure to adjust the pupil diameter and a PDMS-based composite film to simulate posterior capsules with different degrees of turbidity. It integrates a pupil adjustment system and an adjustable structure of an artificial lens to form a closed-loop training system of anatomical simulation and dynamic operation.
It significantly improved the skill training effect of doctors when performing YAG laser posterior capsulotomy, reduced the risk of intraocular lens damage and pupil injury during the operation, and improved laser focusing accuracy and pupil adaptability.
