This paper presents the development of a low-cost cataract surgery simulator for trainees to practise phacoemulsification procedures with computer-generated models in virtual environments. It focuses on the training of cornea incision, capsulorrhexis and phaco-sculpting, which are simulated interactively with computationally efficient algorithms developed for tissue deformation, surface cutting and volume sculpting.Intuitive two-handed human-computer interactions are achieved with six degrees-offreedom haptic devices. Performance of trainees on manual dexterity is recorded with quantifiable metrics. The proposed virtual-reality system has the potential to serve as an alternative training tool to supplement conventional cataract surgery education.

“…The Accreditation Council for Graduate Medical Education (ACGME) requires that each ophthalmology residency training program provides a wet laboratory for residents to prepare intraocular surgery prior to live human surgery [28]. Training residents in cataract surgery has been a challenge for residency programs as a result of several factors [28]:…”

To increase the timeliness, objectivity, and efficiency in evaluating ophthalmology residents' learning of cataract surgery, an automatic analysis system for cataract surgery videos is developed to assess performance, particularly in the capsulorhexis step on the Kitaro simulator. We utilize computer vision technologies to measure performance of this critical step including duration, size, centrality, circularity, as well as motion stability during the capsulorhexis procedure. Consequently, a grading mechanism is established based on either linear regression or non-linear classification via Support Vector Machine of those computed measures. Comparisons of expert graders to the computer vision-based approach have demonstrated the accuracy and consistency of the computerized technique.

“…Computerized simulation in the medical area started in 1960 with a graphic communication system (Khalifa et al, 2006). Computers facilitated the mathematical description of the human physiology and pharmacology as well as the worldwide communication and the design of virtual worlds (Smith & Daniel, 2000).…”

“…At the same time, UltraSim® reproduced the relevant abdominal pathology in obstetrics and gynecology; then, the ophthalmic training system evolved into virtual reality with EYESI® produced by VRMagic; this one was initially designed as a simulator of vitreoretinal surgery and then it became the learning tool of a deeper ophthalmic quirurgic procedure (Khalifa et al, 2006). The first training program based on simulation of neonatal resuscitation was developed in Standford University by the mid 90's (Halamek et al, 2000); then, Gaumard Scientific Company produced a mannequin of a neonate capable of simulate cyanosis.…”
