Abstract
Microsurgical instruments having combined illumination, laser ablation, and viscoelastic injection functions. A surgical instrument includes a probe having a main lumen and a port at a distal end thereof. The probe may further include one or more optical fibers within the main lumen, the optical fibers configured to project laser light and illumination light. Laser light may be emitted from the distal end of the probe for disrupting an ocular tissue, while illumination light may be simultaneously emitted, axially or laterally, to provide enhanced visualization of the intraocular space during tissue disruptance. Upon disrupting the tissue, a viscoelastic fluid may be injected from the port to maintain an integrity of the intraocular space.
