Traditional IOLs are monofocal, correcting vision at one distance only, usually far vision. The latest monofocal IOLs, known as aspheric IOLs, have been proven to also improve image quality and contrast sensitivity.
Aspheric IOLs, such as the Hoya Surgical Optics AF-1 Aspheric lens, provide a significant improvement over vision with a cataractous lens. Studies show that patients with the HOYA AF-1 aspheric lens experience improved contrast sensitivity (which means the ability to see objects that may not be outlined clearly or that do not stand out from their background) and better image quality. However, you will still need glasses or bifocals to read or use a computer after surgery, especially if you already suffer from presbyopia.
The HOYA AF-1 Aspheric lens is manufactured using cutting-edge technology, and the advanced design not only helps to keep the lens properly positioned and stable in your eye, but also gives you excellent image sharpness. The HOYA AF-1 Aspheric lens is an effective, safe, and reliable treatment for cataracts.
