[Research progress of visual prosthesis].

Vision is one of the most important human sensations about the surrounding world. Visual deprivation not only markedly affects the life of blind people, but also gives a heavy burden to their family and the society. A visual prosthesis is an electronic device that helps the blinds to regain visual perception by directly stimulating the visual pathway using the microelectrodes implanted into the body.

[The relationship of magnification change and visual acuity after implanting phakic anterior chamber intraocular lens for extreme high myopia].

Objective: To investigate the change of retinal image magnification and its relationship to post-operative best corrected visual acuity (BCVA) after implanting phakic anterior chamber intraocular lens for extreme high myopia.

Methods: 30 eyes in 23 patients with -15.13 to -29.
