| Abstract: | A dynamical simulation method is presented to model the cornea deformation in surgery of laser thermokeratoplasty. The virtual cornea is constructed as a mass-spring system. The corneal surface tension is simulated by damping spring stretch between mass points on the cornea model. The aqueous humor in the eyeball is modeled as ideal gas, and the intraocular pressure is simulated by gas pressure. The coagulation force is exerted on each photocoagulation spot to demonstrate its collapse caused by the condensa... |
