Femtosecond Laser Assisted Cataract Surgery

Millions of Americans suffer from cataracts. More than three million cataract surgeries are performed in the U.S. annually. One in three, mostly seniors, will have cataract surgery in their lifetime. The surgery performed is intended to remove the natural lens in the eye, that has become clouded or milky, over time. To restore focus, a permanent artificial lens replacement is implanted at the time of cataract removal.

Although our eyes share similar anatomy, each and every eye is different in how it sees, much like a fingerprint. By using the computer controlled LenSx Laser, Dr. Joseph can obtain special high resolution images of your eyes to identify these differences, thus customizing your cataract surgery experience in ways not attainable with traditional methods. With increased surgeon control, Dr. Joseph can perform some of the more intricate parts of the surgery with more precision. This results in more predictable outcomes.


Traditional cataract surgery has always involved the use of a surgical blade, used by hand, to create several small incisions in the eye. A bent needle or forceps is used to make an opening in the cataract outer membrane, which is referred to as the capsulotomy. With Laser Assisted Cataract Surgery, these incisions and the opening in the cataract membrane are now made by a laser. This technology allows Dr. Joseph to plan and perform various parts of the cataract surgery with laser precision. The laser also softens the central core of the cataract permitting easier removal of the cataract. Ultrasonic energy has traditionally been used to remove the core, but now with laser assisted cataract surgery, the amount of ultrasonic energy necessary can be reduced. This results in less damage to the intraocular structures.


The laser can also be employed to plan, locate, and perform precise incisions on the cornea to customize treatment of astigmatism during cataract surgery. For patients who are seeking glasses independence, the laser may be utilized to improve their outcome in conjunction with advance technology intraocular lenses, both for those with cataracts and those without cataracts who are interested in Refractive Lens Exchange (RLE).
