Abstract Details

Purpose:

Cataract surgery simulation is integrated into many ophthalmology training programs. Simulation allows rehearsal in an artificial, safe and measured environment. As such it has been shown enhance surgical skill and improve patient outcomes in phacoemulsification surgery. We provide a review of the background, current status and future directions of surgical simulators pertaining to cataract surgery.

Setting:

Frimley Park Hospital NHS Foundation Trust, Surrey, UK

Methods:

Pubmed database was systematically searched until April 2004. References from retrieved articles were reviewed to broaden the search. We analysed studies validating the effectiveness and deficiencies of simulation for training and assessment in cataract surgery. We documented simulation types (virtual reality, tablet-based, bench models and animal models). The feasibility, validity, reliability and educational impact of the simulators were also examined.

Results:

32 articles were selected on the basis of relevance to cataract surgical simulation and validated results. Eleven articles reviewed construct/concurrent validity for virtual reality simulators. We were able to identify three virtual reality simulators that are in various stages of development and validation: EYEsi, MicrovisTouch and PhacoVision. Bench-top models included artificial silicon eyes, capsulorhexis training with babybel®, grapes or tomatoes. Animal models of simulation that have been published were based on porcine and rabbit eyes. We also noted development of newer touch-tablet based simulators including touch surgery and cataract-mobile.

Conclusions:

Cataract simulation models are valid and reliable for the initial stages of training and monitoring progression of surgical skill acquisition. Cataract simulation offers potential to shorten learning curves for surgical techniques without risk to patients. Research continues to drive the development of increasingly more advanced, realistic and portable models which allow rehearsal of steps in cataract surgery.
