Grin fiber multi-spot laser probe

A surgical probe, comprising:

• a cannula assembly, having
• a graded index (GRIN) fiber that is configured to receive a multi-spot light beam at a proximal end and to emit the multi-spot light beam at a distal end, and a cannula encasing the GRIN fiber;
• a handpiece coupled to the cannula assembly with a proximal portion of the GRIN fiber extending into a proximal end of the handpiece, the handpiece configured to be manipulated by a surgeon or a surgical machine to control positioning of the distal end of the GRIN fiber;
• and
• an adapter, having
• a distal end configured to receive the proximal portion of the handpiece containing the proximal portion of the GRIN fiber,
• a proximal end, configured to couple to a light guide via a connector and to receive a light delivered by the light guide from a laser source to the adapter, and
• an interface configured between the distal end of the adapter and the proximal end of the adapter;
• wherein the interface is outside a patient's eye when the cannula is inserted into the patient's eye during a photocoagulation procedure;
• wherein the proximal end of the GRIN fiber is spaced from a distal end of the light guide by a pre-selected distance inside the adapter thereby coupling the light delivered by the light guide to the proximal end of the GRIN fiber in the adapter;
• wherein the cannula is removably docked to the adapter.
