MICROSCOPE FOR OPHTHALMOLOGIC SURGERY |
摘要 |
The microscope for ophthalmologic surgery 1 can perform astigmatism measurement for a patient's eye E by using a projection-image forming part 13 attached to a microscope 6. The projection-image forming part 13 is provided with multiple bright points (LEDs 131-i) for astigmatism measurement that are arranged in a ring, and a fixation target 131c arranged inside the ring-shaped arrangement. Based on a photographed image of the patient's eye E in a state in which the LEDs 131-i and the fixation target 131c are projected thereto, a displacement calculating part 92 detects the fixation state of the patient's eye E relative to the fixation target 131c. A controller 60 controls the LEDs 131-i and the fixation target 131c based on the detection result of the fixation state.
