Cataract Surgeries with Higher Precision and Accuracy
Cataract surgery involves removing the cloudy lens and replacing it with an intraocular lens implant (IOL) in order to provide focus. Most commonly, the IOL is focused for distance and patients will need glasses for seeing near and reading. There are multifocal IOLs, such as ReSTOR and Technis, that allow for distance, near, and sometimes intermediate correction. They are the best opportunity for patients to gain spectacle independence and freedom from wearing glasses after cataract surgery.
Many cataract patients also have astigmatism, which is when the surface of the eye is not completely round, but rather steep on one side and flat on the other (akin to a football). This irregularity in the curvature leads to distortion and blurring of the vision. A toric IOL can correct for that astigmatism at the time of cataract surgery. For patients with higher degrees of astigmatism, it provides the sharpest and clearest vision, compared with the basic IOL. Another option for reducing astigmatism during surgery is a limbal relaxing incision (LRI) in the cornea. Our surgeons can guide you on which IOL is right for you.

Laser-Assisted Cataract Surgery with Alcon LenSx®
PECG is one of the few practices in the area offering femtosecond laser-assisted cataract surgery (FLACS). This bladeless technology is customized to each patient's needs. It provides incredible accuracy, precision, and tremendous patient outcomes.
Small degrees or amounts of astigmatism can be corrected with the laser, which improves sharpness in the vision. The laser can be used to break up the cataract prior to removal with the traditional phacoemulsification instrument, which lowers the amount of energy used in surgery. Lowering the energy used to break up the cataract makes the procedure safer for harder, denser, more mature cataracts and also conditions with unstable cataract/lens support. Plus, lower energy makes it safer for eyes with Fuchs' dystrophy or corneal guttata, which is when the corneal can swell after surgery from too much energy used.
If you don't like the thought of having a very sharp blade in or around your eye during surgery, LenSx® is the way to go. According to a surgeon at the Wills Eye Institute, "It's as a mix of Harry Potter and Star Wars."
