Analysis of the Ophthalmic YAG-Laser Pulses Inside the Animal Eyes Using an Sscilloscope

Abstract Purpose to study laser irradiation inside the eye. Methods we performed simulation and analysis of the physical effects of YAG laser during laser capsulotomy on the enucleated eyes of mature chinchilla rabbits by pulses fixation with photodetectors and evaluation of them on an oscilloscope. Results our study shows that the effect of the laser pulse on the eye membranes can be measured with a high-speed photodetector, that the results are stable and reproducible, the obtained pulses have the same configuration at all recording points. Conclusion the pulse amplitudes behind the posterior capsule of the lens and at the retina, when the pulse is applied to the posterior capsule, have no statistical difference, this can be explained by diffuse scattering of laser radiation inside the eye by the inner surface of the eye. Using our experimental model, it is possible to calculate the peak of the pulse reaching the retina and use this data in further experiments and clinical practice.
