Abstract

Miniature Miyake-Apple-System: A novel Videoimaging and Recording System for Teaching and Learning Cataract Surgery

Vargas L. G., Auffarth G. U., Specht H., Holzer M. P., Reuland A., Entz B.
Universitäts-Augenklinik Heidelberg

Purpose: to demonstrate a new method to analyze the eye from behind.
Method: An operating table (25 cm x 10 cm) with an aperture in the middle, a high resolution minicamera, a light source similar like the one used for vitrectomy, and several suction rings attached to a vacuum machine were the mainstay components of the system. Twenty-five pig eyes were sectioned 12-mm from the limbus, and prepared as for conventional Miyake-Apple posterior video technique. However, cornea and iris were left in place in order to simulate a closed system.
Results: Adequate view from behind was obtained with the system. Sequences of different phacoemulsification techniques could be performed and recorded with a VCR attached to the minicamera.
Conclusions: A new method for the view of the crystalline lens from behind utilizing a closed-technique video imaging and recording system in cadaver eyes for practicing phacoemulsification was developed. This technique is particularly useful like an instrument of education and practice to diminish the learning curve of residents in training and surgeons in transition.
