摘      要：To provide quantitative feedback on surgical progress to ophthalmologists practicing inner limiting membrane(ILM)peeling,we developed an artificial eye module comprising a quartz crystal resonator(QCR)force sensor and a strain body that serves as a uniform force transmitter beneath a retinal *** a sufficiently large initial force must be loaded onto the QCR force sensor assembly to achieve stable contact with the strain body,the highly sensitive and wide dynamic-range property of this sensor enables the eye module to detect the slight forceps contact force.A parallel-plate strain body is used to achieve a uniform force sensitivity over the 4-mm-diameter ILM peeling *** these two components allowed for a measurable force range of 0.22 mN to 29.6 N with a sensitivity error within−11.3 to 4.2%over the ILM peeling *** this eye module,we measured the applied force during a simulation involving artificial ILM peeling by an untrained individual and compensated for the long-term drift of the obtained force data using a newly developed *** compensated force data clearly captured the characteristics of several types of motion sequences observed from video recordings of the eye bottom using an ophthalmological *** a result,we succeeded in extracting feature values that can be potentially related to trainee skill level,such as the mean and standard deviation of the pushing and peeling forces,corresponding,in the case of an untrained operator,to 122.6±95.2 and 20.4±13.2 mN,respectively.
