Abstract
Velocity distribution in the anterior chamber of porcine eyes under a simulated cataract surgery has been measured by using stereoscopic PIV. Surface location of the cornea was determined based on the images of laser-induced fluorescent light emitted from the fluorescent dye solution introduced in a posterior chamber. Cataract surgery was performed with a coaxial phacoemulsification system. Viscous shear stress on the corneal endothelium was estimated based on the measured mean velocity distribution. The maximum shear stress for most cases reached 3.5dyne/cm^2. This value of shear stress is large enough to detach endothelial cells.
