Abstract

A method and apparatus are provided for conducting laser emulsification of cataracts or the like. The apparatus comprises a tool (2) having a probe (11) extension thereon comprising a removeable and replaceable optical fiber (15), an inner tubular wall defining a first chamber (23), and an outer tubular wall defining a second chamber (41). The first chamber has the optical fiber mounted therein and extending therethrough, and surrounds same with an open chamber, i.e. the first chamber, to which suction can be applied. The first chamber is preferably an outer chamber useable to remove emulsified material from a patient's eye. The outer chamber, i.e. second chamber, surrounds the inner chamber and, for example, provides means by which fluids such as a saline solution can be injected into the region of emulsification. Preferred articulated arm arrangements are provided, to facilitate transmission of light from a laser source to the removeable and replaceable fiber optic. A variety of designs for the removeable and replaceable optical fiber are provided, to facilitate tissue and cataract handling.
