The advanced Tecnis® Multifocal is an implantable lens that significantly improves vision after cataract surgery and corrects presbyopia. It is designed to help regain younger vision and help patient’s become free of glasses. The Tecnis® lens can provide high-quality vision at all distances. Many patients with the Tecnis® multifocal lens experience the best eyesight they have had in years. In fact, nearly 9 out of 10 people do not require glasses after receiving Tecnis® multifocal implantable lenses.
The AcrySof IQ ReSTOR® IOL is a unique technological innovation that can provide enhanced image quality and decreasing dependence on glasses and bifocals. Activities such as watching television, reading, or working at the computer constantly change the focusing power needed to see. The ability to quickly change focus throughout our range of vision is called accommodation. We begin to lose this ability as we grow older, gradually becoming more and more dependent on bifocals or reading glasses.
The AcrySof IQ ReSTOR IOL is divided into two main areas. The first area is a refractive outer ring that focuses light for distance vision, and the second area is a series of apodized diffractive rings in the center of the lens that focus light for near and intermediate vision. Together, these areas provide multiple focal points, for excellent vision at all distances.
Toric IOL technology uses biocompatible materials that have been successfully used in contact lenses and proven safe for the eye. The Toric lens corrects varying degrees of astigmatism at the time of cataract surgery. While the Toric lens will help correct distance vision it does not correct Presbyopia. Therefore most patients still require reading glasses to be able to comfortably perform near and intermediate vision tasks.
Accommodative lenses such as the Crystalens is designed to treat both cataracts and presbyopia. Similar to the eyes natural lens, the Crystalens flexes allowing improved vision at multiple distances. The Crystalens® can reduce or eliminate glasses for most activities, including: reading a book, working on the computer, and driving a car.
Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances.
