Abstract

An IOL injector with a collapsible mechanism and / or a lever driven rack and pinion and an IOL injector with a collapsible injector body are disclosed. The collapsible portion (800) forms a telescoping cylinder and has at least a first sleeve (801) and a second sleeve (804). The first sleeve has a proximal end and a distal end. The second sleeve is slidably coupled with the first sleeve and formed by the distal portion of the body and has a proximal end and a distal end. In the non-collapsed configuration, the distal end of the second sleeve is adjacent the proximal end of the first sleeve. And in the collapsed configuration, the distal end of the second sleeve is adjacent to the distal end of the first sleeve.

Description

technical field

[0001] The present disclosure relates to systems, devices and methods for intraocular lens (IOL) injectors. Background technique

[0002] The human eye, in its simplest terms, functions to provide vision by transmitting and refracting light through a transparent outer part called the cornea, and further through the lens to focus the image onto the retina at the back of the eye. The quality of the focused image depends on many factors, including the size, shape and length of the eye and the shape and transparency of the cornea and lens. When trauma, aging or disease cause the lens to become less transparent, vision deteriorates because less light can be transmitted to the retina. This defect in the lens of the eye is medically known as a cataract. The treatment for this condition is surgical removal of the lens and implantation of an artificial intraocular lens (IOL).

[0003] Many cataractous lenses are removed with a surgical technique called phacoemulsif...
