The word cataract is used to describe a natural eye lens that has
turned cloudy. Cataracts are not a disease, but rather a condition
affecting the eye, which causes gradual impairment of
vision. The development of cataracts is a normal part of the
aging process, but they can result from a number of other
reasons. If left untreated, cataracts can cause needless blindness.
The more efficient solution for restoring vision consists
of extracting the cataract and substituting it with an intraocular
lens, or IOL. Modern advances in micro-surgical
techniques permit cataracts to be removed safely and are
very successful in restoring vision. Nowadays, they are probably
the most frequently performed surgery in the world.
Considering the diffusion and the complexity of the specialty,
training is considered very important. In this context,
the usage of Virtual Reality based training systems would
greatly help in improving the learning curves and the quality
In this project, we study and develop specialized physically-based
simulations of the capsulorhexis and phacoemulsication tasks, as well
as simple geometric simulations of corneal incision. Our combined
simulator runs on a multiprocessing PC platform and provides
realistic visual feedback with real-time interaction.
The simulator is used in the industry as a component of
ophtalmology training applications.
