Publication number: 20240009031Abstract: A micro-device for corneal cross-linking treatment includes a body including an outer portion and an inner portion. The inner portion is coupled to the outer portion which is disposed about a periphery of the inner portion. When the body is against an eye surface, the outer portion contacts the eye surface and the inner portion defines a chamber over a cornea of the eye. The micro-device includes an illumination system including a micro-optical element and an optical fiber. The micro-optical element includes micro-LEDs configured to direct photoactivating light through the inner portion to the cornea of the eye when the body is positioned against the surface of the eye. The photoactivating light generates cross-linking activity with a cross-linking agent applied to the cornea. The optical fiber couples the micro-optical element to a light source and includes a surface configured to reflect the photoactivating light to the micro-optical element.Type: ApplicationFiled: September 21, 2023Publication date: January 11, 2024Inventors: Desmond Christopher Adler, Reza Zadno, Paul Bavier, David C.

Patent number: 8062361Abstract: An accommodating intraocular lens implantable in an eye. The lens comprises an anterior portion having an anterior biasing element and an anterior optic having refractive power. The lens further comprises a posterior portion having a posterior biasing element and a posterior optic having refractive power. The anterior optic and the posterior optic are relatively moveable in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens. The lens has an aberration-inducing force characteristic of about 70 mg to about 115 mg to allow aberration-inducing relative movement of the optics when the lens is in the eye, thereby adding optical aberration to the lens which increases depth of focus of the lens. In one variation, the lens has an aberration-inducing force characteristic of 70 mg to 115 mg. Related methods are also disclosed.Type: GrantFiled: August 1, 2005Date of Patent: November 22, 2011Assignee: Visiogen, Inc.Inventors: Tuan Anh Nguyen, Gholam-Reza Zadno-Azizi, Scott Evans, Valdemar Portney
