Premium Replacement Lenses
Like a camera, the eye has a lens that focus objects both near and far on the back of the eye. Over time, that lens becomes less transparent -- this is called a cataract. This is part of the natural aging process. The only effective treatment for a cataract is to remove the lens and replace it with an artificial one.
A standard replacement lens provides very good "monofocal" focusing power for distance vision only, much like a single-vision pair of eyeglasses. You will still be dependent on reading glasses or bifocals for close-up vision. Many people are happy with this choice.
Multifocal Premium Replacement Lens
Cataract patients can now choose a premium "multifocal" lenses for better vision at all distances, including the close vision needed for tasks such as reading, threading a needle, or tying a fishing lure. If it is important for you to be less dependent on reading glasses or bifocals, you may want to consider an advanced premium lifestyle replacement lens implant. These lenses are designed to provide sharper vision with less reliance on glasses or contacts.
The Palo Alto Medical Foundation provides a number of premium lenses for patients - they include:
Advanced Surface Ablation (ASA)
Visian Implantable Collamer Lens (ICL)
If you opt for a premium replacement lens, your surgeon will select the technology that best meets your visual needs.
* Cost: The cost of premium lenses is higher than standard lens replacements. Out-of-pocket cost may be higher depending on your health insurance policy. In discussing your options with PAMF, the doctor's staff will be able to check on your coverage for procedures.
