Embodiment Construction

[0016] An IOL is an artificial lens used to replace or supplement a patient's natural lens when the natural lens becomes diseased or otherwise damaged. The IOL can be placed in the posterior or anterior chamber of the eye. IOLs come in a variety of structures and materials.

[0017] Various instruments and methods for implanting such IOLs in the eye are known. Typically, an incision is made in the patient's cornea through which the IOL is inserted into the eye. In one technique, the surgeon grasps the IOL with forceps and inserts the IOL into the eye through the incision. While this technique is still practical today, more and more surgeons are using IOL injectors, which have many advantages, such as providing the surgeon with greater control when inserting the IOL into the eye, and allowing A smaller incision to insert the IOL. Smaller sized incisions (e.g., less than about 3mm) are preferred over relatively larger incisions (e.g., about 3.2 to 5+mm) because smaller incis...

Abstract

An IOL injector comprises an injector body, a plunger and a plunger collar. The injector body has a lumen wall defining a lumen, a loading bay, a stop, and an opening adapted for delivery of an IOL into an eye. The plunger comprising a plunger body, a plunger shaft and a plunger tip. The collar comprises a hole or a channel, the plunger shaft extending therethrough. The plunger shaft is slidably, frictionally engaged with the collar. The plunger and the collar are arranged within the lumen such that an outer surface of the collar can smoothly slide within the lumen wall from a first location where the tip is proximal of an IOL disposed at the loading bay to a second location where the stop interferes with the collar. The collar has an outer dimension that is substantially equal to a dimension of the lumen.

Description

technical field [0001] The present invention relates to an intraocular lens (IOL) injector, and more particularly to an IOL injector providing plunger control. Background technique [0002] An IOL is an artificial lens used to replace or supplement a patient's natural lens when the natural lens becomes diseased or otherwise damaged. The IOL can be placed in the posterior or anterior chamber of the eye. IOLs come in a variety of structures and materials. [0003] Various instruments and methods for implanting such IOLs in the eye are known. Typically, an incision is made in the patient's cornea through which the IOL is inserted into the eye. In one technique, the surgeon grasps the IOL with forceps and inserts the IOL into the eye through the incision. While this technique is still practical today, more and more surgeons are using IOL injectors, which have many advantages, such as providing the surgeon with greater control when inserting the IOL into the eye, and allowing...
