A system for delivering an intraocular lens (IOL) is disclosed, including: a handpiece including a barrel defining an elongate passage, a pushrod disposed inside the elongate passage, and a plunger coupled to the pushrod; and a delivery unit coupled to a first end of the barrel, the delivery unit including a delivery tube and a lens holder coupled to the delivery tube, the lens holder including a lead haptic shelf arranged to receive a lead haptic of an IOL that is contained inside the lens holder, wherein the lead haptic shelf is configured to fold the lead haptic of the IOL over a body of the IOL while permitting the IOL to travel under the lead haptic shelf when the IOL is displaced from the lens holder to the delivery tube by the pushrod during delivery of the IOL into a patient's eye.

Intraocular lens insertion system

A finger grip for receiving and retaining a syringe body of an injection syringe. The finger grip is easily pressed directly onto the syringe and employs a centering feature and a pair of one way, flexible latches that allow easy attachment to a syringe body yet ensures retention during normal and abnormal use. If a high horizontal component force is applied during normal or abnormal use, the finger grip will not become disconnected in an uncontrolled fashion from the syringe body, which might cause injury and/or damage to a patient being injected. The flexible latches may prevent detachment of the finger grip from the syringe below separation force of about 25 lbs.

Accordingly, embodiments of the present invention provide an IOL insertion device that facilitates the injection of the IOL in a controlled manner. The insertion device includes a front modular portion and an injector. The modular portion may be preloaded with an IOL and coupled with the injector. The injector includes a distal portion, a body, and a plunger. The distal portion includes a front seal which has a longitudinal bore at the center, through which a distal portion of the plunger passes. The plunger tip is tapered. The plunger also includes a sealing element situated between its distal portion and its proximal portion. The sealing element includes a small aperture through which a fluid, such as a viscoelastic or a balanced salt solution ('BSS') and the like, may pass toward the proximal end of the body when the plunger advances distally. As the fluid passes through the small aperture on the sealing element on the plunger, a constant speed and force is maintained as the IOL is ejected into the eye.

Intraocular lens insertion device

A rear-loaded injector cartridge for an intraocular lens (IOL) having a proximal opening that provides a haptic slot. The haptic slot receives a leading haptic of an IOL loaded therein, and temporarily retains the leading haptic while the optic of the IOL is inserted into a holding area of the cartridge. As the optic passes by, the leading haptic folds over the top of the optic, on its anterior side. The length of the haptic retention slot is sufficient to maintain the leading haptic in its anteriorly folded position while the IOL remains in holding area, typically while the cartridge is mated with a handpiece of the injector. The cartridge also has a rear or proximal cut out which advantageously keys with a similarly-sized rail on the handpiece so that the cartridge cannot be inserted in the wrong way.

Back loaded IOL insertion cartridge

An intraocular lens for reducing aberrant optical effects includes a substantially oval, elliptical, or rectangular optic with an anterior surface, a posterior surface and a peripheral region/zone disposed about a central optical axis and a plurality of haptics coupled to the optic. The peripheral region/zone has an inflection region/transition area that is inclined with respect to the anterior surface at an angle between about 40 degrees and 120 degrees with respect to the optical axis. The thickness at the edge of the IOL is less than or about 0.03 mm.

Reduced glare intraocular lens

A protective cap having finger grips, a window, and port. The protective cap may also have one or more clips (or snaps), one or more relief slots, and/or one or more guides. Protective capmay also have a fill indicator and/or a material relief. An insertion system having a handpiece, a pushrod assembly, a cartridge, and a cap with a window and a port. The cap is configured and dimensioned to couple with the distal end of the cartridge. The insertion system may also have a pushrod with a plunger having a marker configured and dimensioned to indicate axially translation of the pushrod assembly within the handpiece.

An intraocular lens for providing vision to an animal or human subject has anterior and posterior sides. The lens includes an optic body, one or more haptics, and one or more marks. Each mark has four or more features disposed along an imaginary line when viewed from the anterior side and/or the posterior side. The mark(s) may be used as an aid in angularly aligning the lens during use.
