Abstract
An ophthalmic surgery probe assembly includes a handpiece having a handpiece body and a hollow tip of a size suitable for insertion into a human eye, the hollow tip extending distally from the handpiece body. A laser connector is provided for connection to a laser source. A first optical fiber terminates at its proximal end in the laser connector and terminates at the distal end in the handpiece for transmitting laser light from the laser source to an eye to be treated, the first optical fiber extending at least partially through the handpiece tip. An illumination connector is provided for connection to an illumination source. A second optical fiber terminates at its proximal end in the illumination connector and terminates at the distal end in the handpiece for transmitting illumination from the illumination source to an eye to be treated, the second optical fiber extending at least partially through the handpiece tip. The tip also includes a fluid path from the distal end thereof to the interior of the handpiece body. The handpiece body has a fluid path in fluid communication with the fluid path of the tip, the handpiece body fluid path extending to the exterior of the handpiece …
