# Simulated phacoemulsification training using the OrbiTau artificial eye: Experience at a single institute

## TL;DR

This study evaluates the OrbiTau artificial eye as a cataract surgery simulator, finding it realistic and effective for training.

## Contribution

The study provides first-hand feedback from surgeons on the OrbiTau's realism and usability for cataract surgery training.

## Key findings

- 90.90% of participants found the OrbiTau lens capsule comparable to human lens during capsulotomy.
- Most participants found OrbiTau easier to use and more realistic than other simulators.

## Abstract

The OrbiTau surgical simulator is a synthetic eye model developed to enhance
cataract surgical training. Herein, we aimed to describe the perspectives of
Harvard’s Ophthalmology faculty and residents regarding the effectiveness of
OrbiTau.

A cross-sectional study was conducted in which 11 surgeons from the
Massachusetts Eye and Ear Infirmary, with prior experience utilizing
simulated phacoemulsification platforms, conducted cataract surgery with the
OrbiTau. Subsequently, they completed a satisfaction questionnaire using the
Likert scale.

Regarding the various OrbiTau components, 90.90% of the participants reported
that the OrbiTau lens capsule was comparable to that of the human lens
during capsulotomy. Furthermore, 72.72% of the participants found that the
OrbiTau lens consistency was analogous to that of the human lens nucleus.
Approximately 63.63% of the participants reported that the model’s posterior
lens capsule resembled the native posterior capsule, and 72.72% of the
participants noted that the model’s red reflex was similar to that of the
dilated human pupil. Most participants believed that the OrbiTau was easier
to use and more realistic than other commercially available simulators.

Our single-institution survey of the Orbitau demonstrated that this model
realistically replicates ocular structures and may be a viable option for
cataract surgery training.
