Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a passage formed in a distal end portion of the intraocular lens injector. The passage may define an interior surface, and one or more rails may be formed on the interior surface so as to displace an optic of an intraocular lens (IOL) being advanced through the passage towards a portion of the interior surface disposed opposite the one or more rails.

An intraocular lens (IOL) system includes an active lens element to provide dynamic optical power for active accommodation. The active lens element has mechanical indentations disposed along a perimeter of the active lens element and the mechanical indentations form structurally weakened locations in the active lens element. A first pair of the mechanical indentations defines terminal ends of a first folding line extending between the first pair of the mechanical indentations, and the first pair of the mechanical indentations promotes folding of the active lens element along the first folding line. The IOL system also includes control circuitry coupled to the active lens element to control the active lens element during the active accommodation.

Implantable pressure sensors and implantable electronics should be packaged in hermetically sealed modules with biocompatible surfaces before being implanted. Packaging designs should be compact and cause little to no interference with the mechanical (and optical) properties or functions of the implant. For a pressure sensor in an intraocular lens, this means that the sensor and packaging should allow the lens to be folded so that it can be implanted through a small incision in the eye. An inventive implantable pressure sensor is coated with a silicone elastomer and hermetically sealed by a multilayer coating of SiO.sub.x and Parylene C, which may also encapsulate other components, including a microcontroller or processor, rechargeable batteries, sensors, resistors, capacitors, wireless transceivers, and/or antennas mounted on a transparent substrate. This combination of silicone gel and multilayer coating isolates the pressure sensor from surrounding tissue while allowing the pressure sensor to measure pressure precisely and quickly.

Foldable intraocular lens (IOL) having a total dioptric power and comprising an optic portion (12) having main anterior and posterior optical surfaces, and incorporating an internal optical feature (13) positioned between the main anterior and posterior optical surfaces are described. The optic portion has a diameter of greater than 6.0 mm and a maximum central cross-sectional area of less than 2 mm.sup.2 along the diameter, and the internal optical feature positively contributes to the total dioptric power of the intraocular lens. A method of forming the IOL may include: providing a foldable IOL having an optic portion comprising an optical, polymeric lens material and having an anterior surface and posterior surface and an optical axis intersecting the surfaces; and forming at least one laser-modified layer disposed between the anterior surface and the posterior surface with light pulses from a laser by scanning the light pulses along regions of the optical, polymeric material to cause changes in the refractive index of the polymeric lens material; wherein the laser-modified layer forms the internal optical feature that positively contributes to the total dioptric power of the IOL. A method of inserting the IOL into an eye may include folding the IOL, making an incision of less than 3.0 mm length, and inserting the folded IOL through the incision.

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.
