A cataract is a slow, progressive clouding of the eye's natural lens. It interferes with light passing through the eye to the retina.
Over time cataracts typically result in blurred or fuzzy vision and sensitivity to light.
Using the most up to date methods, surgery is typically performed using a small incision, phaecoemulsification technique. This means that the cataract surgery is accomplished using the smallest possible incision, and removal of the lens material is accomplished using an ultrasonic needle.
Intraocular lens come in a variety of materials and designs. Your surgeon generally chooses a lens made of a material that is best suited to your individual situation.
Following proper dilation of the pupil and preparation of the surgical area using betadine or other cleansers, a topical anesthetic is administered to the surface of the eye. An incision of 2.5 to 3 millimeters in length is then created.
Another dose of anesthetic is then administered inside the eye through this incision. The front part of the lens envelope, known as the lens capsule, is carefully opened so that the lens material can be removed.
Once all of the cataract material has been removed, and assuming that the lens capsule which was opened at the beginning of the surgery remains strong enough to support the lens implant, a folded intraocular lens specifically chosen by the surgeon to suit your individual needs is then inserted through the original incision and maneuvered into the lens capsule and then centered. The lens will remain inside your eye in this location without moving.
The AcrySof ReSTOR lens is a foldable IOL that represents breakthrough technology because of its unique, patented optic design, which allows patients to experience the highest level of freedom from glasses ever achieved in IOL clinical trials.
The AcrySof ReSTOR IOL uses a combination of three complementary technologies: apodization, diffraction and refraction, to allow patients to experience a full range of high-quality vision without the need for reading glasses or bifocals.
During U.S. clinical trials, the results with ReSTOR were remarkable:
We provide the technology that makes freedom from all glasses possible when Lasik does not apply.
The ReSTOR lens, a multifocal implant with so-called apodized diffractive lens, the CrystaLens, an accommodative implant, and the ReZoom lens which is another multifocal lens do much to free people of the need for glasses not only for long vision but also for reading and intermediate vision.The Verisyse lens implant and the Visian ICL implant both are designed to bring excellent distance vision for people who do not have cataracts and whose eyes are too nearsighted to be adequately helped with LASIK.
