Cataract surgery involves removing a clouded natural lens from inside the eye and replacing it with a plastic one. While the operation itself hasn't changed much over recent years, the plastic lenses have. The biggest advantage of the newer lenses is their ability to reduce the need for glasses after surgery, says a newly updated report from Harvard Medical School.

There have been great advances in artificial lens technology. Examples of this include the AcrySof® ReSTOR® lens and the AcrySof® IQ lens. Today, the AcrySof® family of lenses are among the most frequently implanted lenses in the world. This is largely due to the long-term clinical results of the lens. Furthermore, these lenses are made of a patented material developed specifically for the eye.

TECNIS® foldable intraocular lenses are indicated for primary implantation for the visual correction of aphakia in adults in whom a cataractous lens has been removed by phacoemulsification. The lenses are intended to be placed in the capsular bag. Rx Only. Precautions: Do not resterilize the lens; do not soak or rinse the lens with any solution other than sterile saline solution; do not store the lens in direct sunlight. Warnings: Surgeons should consider the risk/benefit ratio for adults with preoperative ocular pathology, including but not limited to inflammation, distorted eye and microbial infection. Adverse Events: Adverse events that have been documented as having occurred following intraocular lens implantation include, but are not limited to, corneal edema, iritis, lens dislocation, hyphema, macular edema and retinal detachment.

Galileo used a long focal length converging lens in one end of the tube (the objective lens) and a short focal length diverging lens at the other end (the lens nearest the eye, or eyelens). If the focal length of the objective is Fo and the focal length of the eyelens is -Fe, the distance between them must be Fo - Fe, and the power (angular magnification) is Fo/Fe. This is called the Galilean telescope, or opera-glass.

[T]his study is a strong indication of how important it is for consumers to follow the lens care instructions outlined by their eye care professionals, as well as ask about the new innovations that are currently available. These new advancements make compliance easier, improve comfort and offer flexibility to the wearer."
