ReSTOR® Aspheric 3D Lens

The ReSTOR® aspheric 3d Lens is an advanced multifocal artificial lens that is designed to replace your eye’s natural lens during cataract surgery or Refractive Lens Exchange. The ReSTOR® Lens provides clear vision at all distances, allowing patients to see clearly without the use of glasses.

Your eyes are constantly adjusting to different light intensities and varying distances. This ability to change distance and focus is known as accommodation. As you age, this quality diminishes and the need for glasses increases. Before surgery, your doctor will evaluate your eyes and customize the lens to your lifestyle and vision needs.

Advantages of the ReSTOR® Lens

ReSTOR® combines apodized and refractive technology to drastically improve one’s vision. Advanced apodization technology improves image and vision quality. This technology was first discovered and used in the development of microscopes; now a similar technology is used in the ReSTOR® lens. The apodizing technology is the gradual tapering of the diffractive steps from the center to the outside edge of a lens to create a smooth transition of light between the distance, intermediate and near focal points.

Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. The ReSTOR® lens consist of both apodized and diffractive zones that work together to focus light for near and distance vision.

Dr. Khanna used the ReSTOR® Lens for his mother’s cataract surgery, and she remains very happy with the outcome.

ReSTOR® Aspheric 3D: The Next Step

The ReSTOR® Aspheric 3D Lens is a further advancement of this technology. Asphericity added to the lens gives clearer distance vision. It eliminates the waxy vision observed with the early generation ReSTOR® lenses.

The power of the reading components is decreased from 4 diopters to 3 diopters. This allows the patients to read at a more comfortable distance. The number of apodized steps is decreased from 9 to 6, reducing the glare first observed with these lenses. This is a great lens if you want to have great distance and near vision and want to be glasses free at all distances.
