High-Precision Measurement of Contact Force Applied to the Fundus of the Eye in Intraocular Surgical Training

Abstract

In intraocular surgical simulator, the measurement mechanism of contact force to the retina model by forceps has been developed. We purposed to minimize the error of measurement value depending on contact position within a radius of 2 mm, which is a contact range in the actual surgery. As a solution, the eye module, embedded with the parallel-plates strain body and the cantilever-type QCR (quartz crystal resonator) load sensor fixed at both ends, was fabricated. Consequently, we succeeded in minimizing the error of sensitivity and sustaining enough load resolution. Besides, it was confirmed that the contact force during surgical simulation could be measured with this model.
