Hingeless cartridge for intraocular lens injector providing haptic control

Abstract

A method of loading an IOL having an optic and a leading haptic into a cartridge, comprising folding the leading haptic radially inward relative to the optic as the IOL moves into a lumen of the cartridge, by using a proximal end feature of the cartridge.

Description

technical field [0001] The present invention relates to an injector for an intraocular lens (IOL) and a method of using the injector. Background technique [0002] An intraocular lens (also referred to herein as an IOL or simply a lens) is an artificial lens used to replace the natural lens of the eye when the natural lens is diseased or otherwise damaged. In some cases, the natural lens may remain in the eye with the implanted IOL. The IOL can be placed in the posterior or anterior chamber of the eye. [0003] IOLs come in a variety of configurations and materials. Various devices and methods for implanting such IOLs in the eye are known. Typically, an incision is made in the patient's cornea and an IOL is inserted into the eye through the incision. In one technique, the surgeon uses surgical forceps with opposing blades to grasp the IOL and insert it into the eye through an incision. Although this technique is still practiced today, more and more surgeons are using IO...

AI Technical Summary

Problems solved by technology

For example, it can be difficult to control the orientation of the optic and haptics during movement through the cassette lumen, especially if the IOL folds or compresses inside the nozzle

Additionally, problems may be encountered during engagement of the top of the plunger with the IOL, resulting in damage to the optic, haptics, or both
