Femtosecond Laser Surgery can improve precision and outcomes

Cataract surgery is the most common surgery globally, with roughly 19 million procedures performed each year, approximately 3 million of those in the United States.

Femtosecond Laser-Assisted Cataract Surgery (FLACS) was approved by the U.S. Federal Drug Administration (FDA) in 2010. You may already be familiar with the femtosecond laser — it’s been used since 2001 in LASIK surgery to correct nearsightedness, farsightedness, and astigmatism. The same laser technology can provide more refined and predictable results during cataract-removal surgery.

Cataract surgery is most commonly performed using a technique called phacoemulsification, also known as phaco. Traditional phaco surgery uses sound waves to break up the crystalline lens that has hardened over time into a cataract. FLACS can improve upon traditional phaco techniques and is approved for use for the following steps during cataract surgery:

Laser-Assisted Incisions

Most cataract surgery requires two initial incisions into the sides of the cornea. These incisions are beveled to act as a door and become self-sealing from the pressure in the eye. Traditionally made with a surgical blade called a keratome, the femtosecond laser can also make these incisions into the tissue. Precise incisions are critical for self-sealing and to prevent infection.

Precise Opening of the Lens Capsule

After the incision is made, the next step is to open the lens capsule to access the cataract. This procedure, called curvilinear capsulorhexis, is traditionally done with a capsulotomy needle to make a tiny flap, then Utrata forceps are used to complete the procedure. The laser does this step by cutting the opening circularly and removing the cut circular anterior capsule with forceps. A centered, circular capsule is essential for good intraocular lens placement.

Cleaner Cataract Disassembly

To remove the dense cataract through the small incision, it must be broken up into smaller pieces and vacuumed out of the eye. The phaco technique does this with sound waves that act like a microscopic jackhammer within the eye. In contrast, the femtosecond laser breaks the lens into pieces before entering the eye so that less phacoemulsification energy is required to break up the cataract. The phacoemulsification handpiece is then used to vacuum out the pieces.

Precise Incisions for Astigmatism

For patients with astigmatism, toric intraocular lenses are the most accurate technique to improve astigmatism during cataract surgery. Small limbal relaxing incisions on the cornea’s edges can be precisely made with the laser to fine-tune the correction of astigmatism.


In summary, although traditional phaco surgery is remarkably safe and effective for cataract removal, the femtosecond laser can help surgeons improve accuracy and outcomes.
