摘要： A microscope for ophthalmologic surgery is provided which can measure astigmatic axis angles with high accuracy regardless of the drawing positions of the patient's eye in an image frame. Astigmatism distribution information 71 showing the distribution of the astigmatism parameters resulting from the power distribution of an imaging optical system at least is stored in the storage 70 of the microscope for ophthalmologic surgery 1. An astigmatism information calculating part 92 calculates astigmatism information based on images obtained by photographing the patient's eye E with an imaging element 56a while light from the group of LEDs 131-i is being projected. An astigmatism information correcting part 93 corrects this astigmatism information based on the astigmatism distribution information 71.

摘要： According to an embodiment, an attachment is attached to a main body part and has multiple bright points arranged in a ring. A calculation part calculates a first astigmatic axis angle based on an image obtained by using an imaging optical system to photograph the patient's eye while the multiple bright points are projected thereto. A storage stores the calculated first astigmatic axis angle and/or a second astigmatic axis angle measured before surgery. A mechanism changes the orientation of the main body part. A first input part inputs orientation information indicating the orientation of the main body part. A correction part corrects the first astigmatic axis angle and/or the second astigmatic axis angle based on the input orientation information. A display part displays the corrected first astigmatic axis angle and/or the corrected second astigmatic axis angle.

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.
