Cost-effective and adaptable cataract surgery simulation with basic technology

To assess the subjective validity of a cost-effective and adaptable cataract surgery simulation technique using basic technology.

We devised and filmed a range of simulation techniques that mimic steps of phacoemulsification cataract surgery using various "everyday" basic materials. This video was combined in a "parallel" fashion with live cataract surgery so that all steps of surgery were simulated. Subsequently, we distributed an online subjective validation questionnaire on Google Forms with the embedded simulation video in a generic invitation that was forwarded via email and/or text messages/WhatsApp messenger amongst Ophthalmologists of all grades within our regions (Kent, Surrey and Sussex, London and Wales Postgraduate Deaneries).

Face validity: 66 (99%) participants agreed that the explanations in the video were clear and 53 (79%) concurred with the realistic feel of simulated technique. Instrumentation and adaptations demonstrated were deemed user friendly and conducive to replicate by 99% participants. Content validity: 60 (90%) of participants agreed the techniques described in the video reflected the technical skills required to train cataract surgeons. Forty-nine (74%) agreed that the simulation techniques were relevant for acquiring other generic and transferable microsurgical and manual dexterity skills.

We demonstrated subjective validity of our cost-effective cataract simulation technique. Our model can be used as an adjunct to intraocular and virtual reality training for cataract surgery by removing the barrier of cost and improved exposure to real instruments used in cataract surgery.
