| Research Abstract |
Velocity distributions in the anterior chamber of porcin eye under simulated cataract surgery have been measured. Viscous shear stress on the corneal endothelium was estimated based on the measured mean velocity distribution. The shear stress was estimated to be 7 dyne/cm^2 in maximum. In order to reduce the velocity of the irrigation fluid issued from the sleeve, a new sleeve was developed by using rapid prototyping method. In the case of study in a water container, the velocity has been reduced 30%.
