Resumen
The purpose of this paper is to carry out a scientific literature review of the basic principles used by an adaptive optics (AO) visual simulator system and its main applications in optometry and ophthalmology. AO systems are used to measure, correct, and simulate wavefront aberrations. They all share three basic components: a wavefront sensor, a wavefront corrector, and a control computer. The visual simulator uses a Hartmann-Shack aberrometer with a square array of 1024 lenslets to measure the wavefront at 850 nm, while the AO system uses a deformable mirror with 52 independent electromagnetic actuators under a membrane as a correcting element. A commercially available software allows control of the deformable mirror surface. The technique has many applications, such as optimization of instrument optical quality to improve visualization of the retina, study of vision quality, and the development of new optical designs for intraocular lenses, customized contact lenses or wavefront-guided refractive surgery. Thus, AO could be useful for choosing the best surgical technique without having to perform surgery.
