Laser cataract surgery, also known as femtosecond laser-assisted cataract surgery (FLACS), uses a femtosecond laser to perform some of the key steps in cataract surgery. In traditional cataract surgery, the surgeon uses a blade to make a small incision in the cornea to access the cloudy lens. They then use ultrasound energy to break up the lens and remove it from the eye. Finally, they insert a new artificial lens into the eye through the same incision. In laser cataract surgery, the femtosecond laser is used to perform some of these steps, making the procedure more precise and efficient.
