CA 2241137

A fiber optic integrated phacoemulsification system is disclosed comprising surgical handpieces (1) for cataract surgery which incorporate fiber optic bundles (4) that transmit visible light to enhance visualization by intraocular illumination. Patient safety is improved by the oblique lighting to the retina, thereby reducing the necessity of direct coaxial light from the surgical microscope. The fiber optic bundles (4) enable the application of laser energy or visible light and permit endoscope visualization of intraocular structures either through the surgical handpiece (1) or through an end piece attachment (3).

La présente invention concerne un système intégré de phacoémulsification à fibre optique. Il comprend des pièces à main chirurgicales (1) pour l'opération de la cataracte, dans lesquelles se trouvent des faisceaux de fibres optiques (4) qui transmettent de la lumière visible pour améliorer la vision par illumination intra-oculaire. La sécurité du patient est améliorée par l'éclairage oblique de la rétine, ce qui réduit la nécessité d'avoir une lumière coaxiale directe provenant du microscope chirurgical. Les faisceaux de fibres optiques (4) permettent d'employer de l'énergie d'un laser ou de la lumière visible ainsi que la visualisation endoscopique de structures intra-oculaires soit à travers la pièce à main chirurgicale (1), soit à travers un accessoire (3) monté sur la pièce d'extrémité.
