Journal: BioMedical Optics Express
Volume: 6 (3)
Pages: 1010-1020
Year: 2015
ISBN: 2156-7085

Abstract:
We have designed an intraocular telescope for the posterior chamber of the human eye of patients with age related macular degeneration. The basic design is composed of two decentered high optical power lenses ( + 66D and −66D) […]

Binocular open-view instrument to measure aberrations and pupillary dynamics

Autores: Emmanuel Chirre, Pedro M. Prieto and Pablo Artal
Revista: Optics Letters
Volumen: Vol. 39
Paginas: pp. 4773-4775
Fecha: 07-08-2014 (2014)
ISBN: 0146-9592
ABSTRACT
We have designed and built a binocular Hartmann–Shack wave-front sensor using a single microlens array and camerafor real-time aberration measurement of both eyes in an open-view configuration. Furthermore, the use of a longwavelength (1050 nm) laser diode makes the illumination source completely invisible, so […]
