laser–assisted cataract surgery provides surgeons an exciting new option to improve patient outcomes and safety.


Cataract surgery is the most commonly performed surgical procedure world-wide, with about 19 million operations performed annually, nearly three million of which are performed in the United States. Only about 1000 surgeons in the United States, however, have been trained to use the Femtosecond laser technology for cataract surgery, and Dr. Cheung is one them! Introduced clinically for ophthalmic surgery in 2001 as a new technique for creating lamellar flaps during LASIK surgery, it has recently been developed into a laser-assisted tool for cataract surgery.

Femtosecond Laser Technology
The Femtosecond laser technology systems uses near-infrared wavelength light, which  allows the light to be focused at a 3 µm spot size, accurate within 5 µm in the anterior segment.  The benefit of Femtosecond laser technology is the speed at which the light is fired. The focused ultra-short pulses eliminate the collateral damage of surrounding tissues and the heat generation associated with slower lasers.

In laser cataract surgery, an advanced femtosecond laser replaces or assists use of a hand-held surgical tool for the following steps in cataract surgery:

  1. The corneal incision
  2. The anterior capsulotomy
  3. Lens and cataract fragmentation

The precision, accuracy and reproducibility of each of these steps are dramatically improved with the use of this laser, which translates to reduced risks and better visual outcomes for patients with cataracts. More than twice as many patients achieved 20/25 and 20/20 uncorrected vision at one-month post-op in the laser group as compared to the conventional cataract surgery group according to a recent study.

We are proud to be the first office offering this exciting technology in Kitsap County. Make an appointment with Dr. Cheung to see if you might be a candidate for Femtosecond cataract surgery.
