Advantages of Using a Laser in Cataract Surgery

shutterstock_37044946Cataracts are extremely common in older adults. Experts say that one in three people will need to have cataracts removed at some point in their life. Traditionally, the steps of cataract removal surgery were performed with handheld surgical instruments. Today, many cataract surgeons, including the team at Bochner Eye Institute, are incorporating a femtosecond laser into the procedure to perform critical steps of the operation. Laser cataract surgery has been linked to fewer complications and faster recovery of vision.

Here, the Toronto cataract surgeons of Bochner Eye Institute discuss the advantages of laser cataract surgery and what that could mean for the millions of people that need cataract surgery.

Less Energy Required to Fragment the Lens

Cataracts that are treated with a laser require less energy to break up and remove. The reduction in energy leads to fewer complications and side effects after surgery.

Fewer Movements Inside the Eye

Using a laser to access and fragment cataracts also requires fewer movements inside the eye on the surgeon’s part. This lowers the risk of inflammation, swelling and other complications. Vision is also quicker to recover with fewer movements inside the eye and less energy exerted during the procedure.

Precise Incisions

The femtosecond laser is used to create the initial incision on the surface of the eye. Using a laser means the incisions are predictable and precise, every single time. They are also more likely to heal without problems.

Standardized Capsulotomy

The laser is also used to open and remove part of the capsule bag that holds the lens, to create room for the lens implant. Using a laser to complete this step, called the capsulotomy, standardizes it and makes it more precise. This helps to preserve the integrity of the capsule so that it can hold the lens implant without it becoming displaced.

Preserves Cells

Fragmenting the cataract-diseased lens with a laser prevents the loss of cells on the surface of the cornea (called endothelial cells). These cells are important because they preserve the cornea’s clarity; also, they do not regenerate, so it is important to avoid damaging as many as possible.
