During cataract surgery, a small ultrasonic probe is inserted into the eye which breaks up, or emulsifies, the cloudy lens into tiny pieces and gently sucks, or aspirates, those pieces out of the eye. Phaco surgery requires a small incision of only 3.2 mm or less. To make your procedure as painless as possible, anesthesia is a combination of local and/or topical along with IV sedation.
With the recent advance of foldable IOLs, artificial lenses can be implanted through the same small incision that is created in the phaco procedure. These IOLs are made of a flexible material, allowing them to be folded for implantation. Once inside the eye, the lens unfolds and returns to its original shape.
Until recently, cataract patients have been forced to choose between
distance or near vision after surgery, relying on reading or distance
glasses to see clearly at all ranges. Dr. Wong utilizes the latest
advancements in cataract surgery lens implants, allowing the option of
having both distance and near vision without depending on glasses. These
advanced lenses are described in greater detail below
ReSTOR® is an IOL (intraocular lens) that provides cataract patients with and without presbyopia a quality range of vision. In clinical trials, 80 percent of patients reported “never” wearing reading glasses or bifocals following bilateral cataract surgery. The vast majority of patients who undergo cataract surgery today receive traditional IOLs, which typically require patients to use reading glasses or bifocals for near vision following surgery.

The ReSTOR® lens is a foldable IOL that represents breakthrough technology because of its unique, patented optic design, which allows patients to experience the highest level of freedom from glasses ever achieved in IOL clinical trials. It does not rely on the muscles, which weakens with age, to enable the eye to quickly change focus to see objects at near, intermediate and far distances. This allows 80 percent of cataract patients with and without presbyopia (age-related vision loss) the ability to see clearly without the aid of glasses or bifocals.
It is important to understand that while ReSTOR® is a new technology, intraocular lenses are not new. Lens implant surgery for cataracts is the most commonly performed surgery in the U.S. and has been performed for more than two decades.
However, for years medical researchers have been eager to find a lens that would not only treat cataracts but give patients the range of vision they wanted. Until recently, the only lens implant available was a “monofocal” lens that accommodated sight at a fixed distance, typically medium range. ReSTOR works by diffractive and refractive properties which allow an exceptionally high degree of freedom from any form of corrective eye glasses.

The ReZoom™ multifocal intraocular lens (IOL) helps patients focus clearly on objects at a range of distances and in varied light conditions, so they can be free of glasses or contact lenses after cataract surgery. The ReZoom lens features five spherical segments with smooth transitions in between so the eyes focus seamlessly from one distance to the next. The center of the lens is optimized for bright light and distance vision, while the fourth zone supports near-vision in a variety of light conditions, and the outermost zone accommodates for low-light distance vision (such as when driving at night). The ReZoom is also specially designed to reduce internal reflections and minimize glare.
Toric IOLs are specially designed for patients with astigmatism. Traditionally, surgical correction of astigmatism required making a series of small incisions (called LRIs) around the cornea to make it more spherical instead of football-shaped. Implanting toric IOLs often improves vision due to astigmatism without the need for these extra incisions, and also allows patients to enjoy a faster, more comfortable recovery.
