Modular IOL systems including a base and a lens, wherein the lens includes fixed and actuatable tabs for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or post-operatively. Drug delivery capabilities and/or sensing capabilities may be incorporated into the base. Injector devices may be used to facilitate placement of the base and the lens sequentially or simultaneously into the eye.

Intraocular lens delivery devices and methods of use.

An intraocular lens that is capable of being inserted through a micro-incision includes an optic having an anterior and a posterior surface and a plurality of projections extending from the anterior and posterior surfaces. The anterior and posterior surfaces include a recess. The optic is implanted such that a rim of the capsulorhexis is disposed in the recess such that the plurality of projections grip the capsular bag.

An intraocular lens insertion device having a configuration in such a manner that, with the displacement of a haptic toward the convex side of an optical portion, which can be deformed in a curved shape, restricted by an engaging part provided to the tip part of a plunger, the haptic is deformed in a curved shape in the direction in which the haptic approaches the optical portion. The configuration allows, when the intraocular lens is pushed out by the plunger, the haptic to enter a gap formed on the concave side of the optical portion which has been deformed in a curved shape.

Provided is technology which can prevent plunger deformation and further stabilize an intraocular lens insertion operation, even when an insertion tube section of an intraocular lens insertion apparatus has been further reduced in terms of the diameter thereof and has been made flatter. The intraocular lens insertion apparatus includes: a tip end region where a plunger comes into contact with an intraocular lens main body and an intraocular lens holding section; and a bar-shaped section extending from the rear end of this tip end region to the rear of the plunger. The bar-shaped section has a fixed thickness in the direction of the optical axis of the intraocular lens, and has an increasing thickness in a portion where the distance from the tip end of the tip end region is equal to or greater than a predetermined distance in a direction perpendicular to the optical axis direction and perpendicular to the plunger advancement direction.

Intraocular lens delivery devices and methods of use.

A method for reducing the transmittance of ultraviolet radiation through an intraocular lens to 10% or less at 370 nm by (a) polymerizing a mixture comprising: at least one first monomer and a second monomer comprising a trisaryl-1,3,5-triazine moiety, (b) forming an optic portion from the copolymer wherein the second monomer is present in about 0.10 to about 0.20 percent by weight of the overall polymer and wherein the optic portion of the intraocular lens displays essentially the same physical properties such as, for example, refractive index as the optic portion of the intraocular lens formed from the polymerized mixture of (a) without the second monomer, but otherwise identical conditions. Additionally, a method for preventing the transmittance of at least 90% of ultraviolet radiation at 370 nm through a foldable intraocular lens comprising: (a) incorporating a monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety into at least one polymer and (b) forming the polymer into a material suitable for use as an intraocular lens, wherein the monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety comprises 0.10 to 0.15 weight percent of the overall dry polymer.

An intraocular lens having an optic and at least one semi-rigid, haptic connected to the optic, both of which may be acrylic. The intraocular lens can have a fixed longitudinal length, e.g., the same fixed length pre-operatively and post-operatively. The intraocular lens can resist deformation, despite contraction and relaxation of the ciliary muscle and fibrosis within the capsular bag, after implantation into the eye using, for example, by the semi-rigid haptics. The intraocular lens can be sufficiently flexible to be compressed from an original configuration to a compressed configuration for insertion into the eye through a small incision and return to the original configuration after implantation into the eye.

A plate haptic for an accommodating intraocular lens. The plate haptic has a haptic body that is substantially rigid in a longitudinal direction and substantially flexible in a transverse direction. A chassis is integral to the haptic body. The chassis causes the haptic body to be substantially more rigid in a longitudinal direction than in a transverse direction.

Intraocular lens loading devices, system, and methods of use. The device and systems can be used to load an intraocular lens into a cartridge, from which it can delivered into a patient's eye. The devices and systems can also be used to simply advance an intraocular lens through any type of loading or delivery device.
