A Retinal Implant System Based on Flexible Polymer Microelectrode Array for Electrical Stimulation,of blindness in adult (.). Despite a near-total loss of the photoreceptors, the inner nuclear and ganglion cell layers survive at fairly high rates in the patients with retinitis pigmentosa (.) and age-related macular degeneration (.). Retinal prostheses have great potential in alleviating the probl

Circuit Designs That Model the Properties of the Outer and Inner Retina,sis to be practical, the device must perform these computations as efficiently as, and at a physical scale comparable with the lesioned network, and should adapt its properties over time, independent of external control. The approach to design a successful prosthesis that faithfully replicates the c

Artisan Toric Lens Implantation for Correction of Postkeratoplasty Astigmatism, four to five diopters (D) ((.)–(.)). It is well known that patients do not tolerate spectacle correction for more than three to four D of astigmatism or anisometropia. Therefore, contact lenses are fitted in 10–30% of patients, and in keratoconus this value may increase up to 50% (.,.). Contact len

Phakic Intraocular Lenses for the Treatment of High Myopia,tment of myopia (.,.), is limited in high myopic eyes, because a residual corneal stromal thickness of 250 µm is essential to minimize the risk of corneal ectasia (.). Apart from that, large excimer laser corrections may result in poor optical quality of the reshaped cornea (.). Clear lens extractio
