Development and Research of an Optoelectronic Device Based on a Wavefront Sensor to Control the form Parameters of Intraocular Lenses

Resumo

An original design is proposed that makes it possible to create a two-channel optoelectronic instrument for diagnostics of the shape and quality of intraocular lenses. This instrument consists of a collimation-type channel and a channel based on a Shack–Hartmann wavefront sensor. The hardware characteristics of the instrument are examined, i.e., the radius of curvature of the wavefront in the plane of the lens raster, and the dynamic range to which possible measurable aberrations of the intraocular lenses are restricted. A methodology is proposed for diagnostics of the design parameters of intraocular lenses. The systematic error of the output parameter of the instrument being developed is examined within the framework of precision calculations. The calculations that were performed made it possible to transfer to the design stages of an optoelectronic instrument based on the wavefront sensor for monitoring the parameters of the shape of intraocular lenses.
