An illumination and laser energy delivery system, providing various flush and extended tip laser and illumination probe configurations for retinal surgery, is disclosed that allows efficient delivery of laser and illumination energy to a surgical site through a device that is smaller than the standard 20 gauge probe conventionally used in endophotocoagulation procedures. Novel constructions, as disclosed, enable the space inside the probe cannula to be used more efficiently than in prior art devices, providing improved performance of the device and system in delivering laser and illumination energy to the surgical site.
