How does cataract surgery work?
For decades now, conventional cataract surgery has involved the use of ultrasound energy, delivered by the tip of one of the small surgical instruments, to break down the old lens (a process called “phacoemulsification”). The fragments of the old lens are then “aspirated” away – literally, sucked out. This is delicate surgery, and is performed entirely manually – meaning that the surgeon requires a very steady hand. The operation is still very safe and has been ‘tried and tested’ millions of times.
What is the corneal incision called?
The operation. The first part of the surgery is the creation of small incisions in the cornea (called “clear corneal incisions”), to allow the surgeon to place surgical instruments inside the eye and perform the surgery, removing the old lens, and introducing the new IOL. The old lens is held in place by a structure known as the capsular bag.
Can you use a femtosecond laser for cataract surgery?
For the last few years, it has also been possible to use a femtosecond laser in a number of parts of cataract surgery. Lasers are even more precise than even the steadiest of hands, as all of their cuts can be planned on the computer in advance and placed exactly where the surgeon wants.

Recovery from the larger incision extracapsular extraction also requires almost a week-long hospital stay after surgery, and limited physical activity for weeks or even months.
