What are High Tech Lenses?

Lens Implants to Fit Your Active Lifestyle

cataract-IOL-eye-doctor-san-francisco.jpgFor most cataract patients, life without reading glasses or bifocals is something they experienced before age 45 and something they thought they’d never experience again. Today, advancements in cataract lens implant technology offer the possibility of a much wider range of natural vision.

High Tech Lens implants are now available that can provide focus for multiple viewing distances and correct for astigmatism. With these lens implants, vision can be clear for long distances as well as up-close, without the use of glasses.

High Tech Lens implants are different from traditional monofocal Intraocular Lenses (IOLSs). Standard IOLs have a flat, smooth surface and focus only at one range, usually distant. To achieve good middle and near vision, patients are required to wear glasses, usually bifocals.

There are several different types of High Tech lens implants; we recommend several types that offer our patients the highest quality of vision:

  • Presbyopia-correcting IOLs: Crystalens®,  ReSTOR®, Tecnis
  • Astigmatic-correcting (Toric) IOLs:  Alcon AcrySof®  Toric, Trulign


The Crystalens was modeled after the human eye. The Crystalens is the only lens implant that bends and flexes like your eye's natural lens, using the eye muscle to focus on objects in the environment at all distances. The Crystalens dynamically adjusts to your visual needs.

The Crystalens Accommodating IOL is made with hinges on each side that are designed to allow the optic, or the part of the lens that you see through, to move back and forth as you constantly change focus on images around you. After a brief time of adaptation, it is expected that you will be able to perform many

tasks, whether far, intermediate or near, with limited dependence on glasses.

The design of the Crystalens has now been combined with astigmatism correction to allow even more refined correction of vision.


The AcrySof ReSTOR IOL is designed to significantly reduce or even eliminate the need for glasses after cataract replacement surgery by providing clear vision distance and near vision.

The ReSTOR IOL is a multifocal lens. Its surface looks like a series of circular steps, thicker in the center and thinner on the edges. Each level focuses light from a different range, from near in the center to distant on the edges. They combine to give the patient a full range of vision with limited dependence on glasses.


AcrySof Toric IOL 

Current technology makes it possible to correct the cataracts that may be clouding your vision – and the astigmatism that may be distorting your vision – all at the same time. The AcrySof Toric IOL replaces your eye’s natural clouded lens during cataract surgery. In addition to clearing vision that was clouded by cataract, it also has the ability to reduce or eliminate corneal astigmatism at the same time.  The result is typically improved distance vision and less dependence on glasses. However, most patients still need corrective lenses for near and intermediate tasks. The AcrySof Toric lens also filters out harmful ultraviolet and blue light.

What is Astigmatism?

Sometimes the surface of the cornea is curved in such a way that vision becomes distorted or blurred. Glasses are generally used to correct astigmatism.  A person who has both cataracts and corneal astigmatism will not regain high-quality distance vision free of glasses after cataract surgery unless the astigmatism is also corrected.
