A system includes a light source configured to emit treatment light and an optical coherence tomography (OCT) device. The system further includes a surgical instrument including a distal portion configured to be inserted into an eye of a patient. An optical fiber is coupled to the light source and to the OCT device and (a) conducts the treatment light along the distal portion to be emitted from a tip of the distal portion and (b) conducts detection light from the OCT device along the distal portion to be emitted from the tip of the distal portion and conduct a reflected portion of the detection light to the OCT device. A controller obtains image data from the OCT device and operates the light source per the image data, e.g., selects a number of pulses for the treatment light based on a thickness of a trabecular meshwork apparent in the image data.

The invention provides an angle rotation expansion type electrocoagulation trabecular incision knife for glaucoma surgery, and relates to the field of trabecular incision knives. The high-frequency electrotome comprises a knife handle, a high-frequency electrotome host, a connecting wire and a negative plate, the electric knife is characterized in that a conductive mechanism is arranged in the knife handle; the conductive mechanism is electrically connected with the positive electrode of the high-frequency electrotome main machine through a connecting wire; an adjusting mechanism is arranged at the lower end of the cutter handle; a cutting mechanism is arranged at the end, away from the cutter handle, of the adjusting mechanism. The outer side of the cutting mechanism is sleeved with a sleeve rod. Through mutual cooperation of a conductive wire, a cutting knife, a negative plate and other mechanisms, after the conductive wire electrifies the cutting knife, the positive electrode of the cutting knife is in contact with the negative electrode of the negative plate when the cutting knife carries out surgical cutting on a patient lying on the negative plate, and then a wound is burnt, blood is coagulated, and the wound is prevented from being damaged. The problem that bleeding of a patient blocks medical staff is solved, and the operation safety is improved.
