ANALYSIS OF THE OPHTHALMIC YAG-LASER PULSES INSIDE THE ANIMAL EYES USING AN OSCILLOSCOPE
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 highspeed 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.
