Innovative Mass. Eye and Ear Cataract Master™ Bridges the Gap
between Wet Lab Training and Patient Surgery
Boston, Mass. (May 29, 2012) – Phacoemulsification cataract surgery is one of the most frequently performed eye surgeries in the United States, with 1.5 million procedures performed each year. It is also one of the most complex procedures to learn. A new, highly innovative, computer-based simulation tool, the Mass. Eye and Ear Cataract Master, bridges the learning gap that residents and ophthalmologists new to phaco must navigate prior to performing actual surgery.
Ophthalmology residents typically train in wet labs and on phacoemulsification simulators that supplement motor skills training before moving on to live patients. This is a challenging leap for surgeons-in-training, even with the most careful oversight by attending physicians. The Cataract Master offers a unique approach for making the transition more successful.
Nearly a decade in the making, the Cataract Master was co-developed by Bonnie An Henderson, MD, F.A.C.S., Harvard Medical School Ophthalmology Residency Training Program Director John I. Loewenstein, M.D., (pictured) Adam Neaman, Ph.D., and several colleagues. The English version of the program is available worldwide through the American Society of Cataract and Refractive Surgery Foundation, the research and charitable arm of a 9,000-member international society dedicated to improving the education and skill sets of anterior segment surgeons.
“The Cataract Master aims to minimize clinical risk while providing residents and practicing ophthalmologists with the most authentic cataract surgical experience possible outside the OR,” Dr. Loewenstein said. “The goal is to boost skills and confidence, to better prepare residents for the surgical experience, and to raise the quality of patient care everywhere.”
Computer–based simulation technology has been used in medical training since the early 2000s, but these tools often did not take into account the hundreds of decision-making requirements that arise during surgery. The Cataract Master is different in that it offers a self-guided, self-correcting curriculum that requires trainees to make decisions based on realistic surgical situations. The simulator, which can be accessed from any personal computer, contains realistic animations along with videos of actual surgeries – complete with expert discussions of each phase of the procedure. The interactive program includes frequent pop-up questions relating to the various surgical steps, with user answers then animated on-screen. If the user makes a serious error, videos provide immediate feedback explaining how the problem occurred, what to do to fix it, and how to avoid making the same mistake again.
“This essentially allows new phaco surgeons to learn from their mistakes and to master life-like surgery without risking injury to a patient,” said Dr. Henderson. “This type of immersion learning is simply not possible any other way, and provides an excellent transition to the operating room.”
To test its effectiveness, the developers conducted a multicenter, randomized trial at eight residency programs, which compared the Cataract Master to traditional teaching tools. Results showed that residents enjoyed using the program and preferred its method of learning. The study results were published in the journal, Ophthalmology, in February 2010.
“The Cataract Master is a unique and original instructional tool for phacoemulsification cataract surgery. The animated simulation provides a realistic interactive experience, with advice along the way via video clips of experts in the field, based on trainee surgical decisions during the exercise. It is an outstanding tool to teach thought processes and decision-making during cataract surgery, highly recommended for ophthalmology resident training,” said Anthony Arnold, M.D., Residency Program Director, Jules Stein Eye Institute, UCLA Dept. of Ophthalmology.
The Cataract Master is available through an annual subscription arrangement and promotes rapid learning while also reducing training cost and scheduling time. It is an ideal tool for those just learning phaco and those who wish to hone their skills and better manage surgical complications. A full help and reference section is included.
A demonstration of The Cataract Master, along with a free trial, is available at www.cataractmaster.org.
Funding for the development of this teaching tool was provided by the Massachusetts Lions Eye Research Fund, Mr. Norman Knight, the US Army, and the Harvard Medical School Department of Ophthalmology.
Massachusetts Eye and Ear clinicians and scientists are driven by a mission to find cures for blindness, deafness and diseases of the head and neck. After uniting with Schepens Eye Research Institute in 2011, Mass. Eye and Ear in Boston became the world's largest vision and hearing research center, offering hope and healing to patients everywhere through discovery and innovation. Mass. Eye and Ear is a Harvard Medical School teaching hospital and trains future medical leaders in ophthalmology and otolaryngology, through residency as well as clinical and research fellowships. Internationally acclaimed since its founding in 1824, Mass. Eye and Ear employs full-time, board-certified physicians who offer high-quality and affordable specialty care that ranges from the routine to the very complex. U.S. News & World Report’s “Best Hospitals Survey” has consistently ranked the Mass. Eye and Ear Departments of Otolaryngology and Ophthalmology as top five in the nation.
