ReSTOR™ Multifocal Intraocular Lens
The ReSTOR™ foldable IOL uses a combination of three complementary technologies: apodization, diffraction, and refraction, to allow patients to experience a full range of high-quality vision with a reduced need for reading glasses or bifocals. This range of vision without glasses is achieved through the optical properties of the IOL. Twelve small concentric rings on the lens create varying points of focus from distance to near. This allows images to be focused at both near and distance to create a higher level of spectacle freedom for patients.
During FDA clinical trials, the results with ReSTOR™ were remarkable.
For patients implanted in both eyes, the following results were achieved:
- 80% of patients reported that after lens implant surgery with ReSTOR™ lenses, they no longer needed glasses or contact lenses to see clearly at all distances.
- In the FDA Clinical Trial, 80% of patients reported never wearing glasses for any activity at any time.
- 94% said they could drive and read the paper without contacts or glasses.
The most common circumstance where glasses may still be required is for intermediate vision. It should also be noted that patients implanted with the ReSTOR™ lens have reported experiencing nighttime glare and halos at a greater frequency than reported by those patients implanted with a standard lens. If present, these symptoms tend to improve during the months following implantation.
Refinements in lens implant technology have advanced significantly in recent years providing a variety of options to fine-tune the vision after surgery. However, it is important to remember that, while cataract surgery with customized intraocular lens implantation frequently results in a reduced dependency or even complete freedom from eye glasses, that it is never possible to guarantee complete freedom from glasses after surgery. In addition, there are other factors besides the implant that can determine the final vision after surgery, such as ageing of the retina, the shape of the cornea, or various other degenerative conditions of the eye.
