A cataract is a clouding of the natural lens inside your eye. Traditional surgery relies on handheld blades, but laser cataract surgery uses computer-guided light for several key steps. Before the procedure begins, your surgeon maps the structure of your eye with detailed imaging. This is what happens during each stage of the process:
Using Specialized Laser
The femtosecond laser sends extremely short pulses of light, and each pulse lasts a tiny fraction of a second. Since the pulses are so brief, they separate tissue with very little heat. This feature limits stress on the cornea and other nearby parts of the eye. The laser does not replace your surgeon, who stays in control of the procedure at every moment.
Before laser cataract surgery begins, the care team places numbing drops in your eye. A small device then rests on the surface of your eye. This device keeps your eye steady, and it connects your eye to the laser system. Patients may feel light pressure during this step, and some notice a brief dimming of their vision.
Making Precise Circular Openings
Your natural lens sits inside a thin, clear membrane called the capsule, and the surgeon needs access to it. The laser creates a round opening in the front of this capsule. Surgeons call this step a capsulotomy, which traditionally involves a handheld tool. The laser version has a few specific features:
- A consistent circular shape
- A size planned in advance from imaging data
- A centered placement based on your eye map
Removing Cloudy Lens Gently
After the capsule opens, the laser softens the cloudy lens and divides it into smaller pieces. This pre-treatment reduces the work left for later tools, and it typically lowers the ultrasound energy needed. Dense cataracts typically require more of this energy during traditional removal. Your surgeon adjusts the laser pattern based on the density of your cataract.
Next, your surgeon makes a tiny incision at the edge of the cornea. A thin probe enters through this opening, where it breaks up and suctions out the lens fragments. The capsule stays in place, and it later holds the new lens. An incision typically seals on its own because of its small size and shape.
The laser’s precision enhances accuracy, and it also aims to minimize potential risks during cataract removal. This tiny incision heals quickly. While the procedure may vary slightly depending on the cataract’s severity, patients typically experience improved vision within days.
Replacing With a Clear Lens
The final step places an artificial lens inside the capsule. The implant is an intraocular lens, or IOL, which folds to fit through the small incision. Once inside, the lens unfolds, and your surgeon positions it in the center of the capsule. Your surgeon will review several lens types with you, and they may include:
- Monofocal lenses: Focus at one set distance
- Toric lenses: Correct astigmatism
- Multifocal lenses: Provide more than one focal point
The IOL is designed to remain securely in place, and it provides clear vision for years after the procedure. This small but highly durable lens is made from materials that are safe and long-lasting. While the procedure is relatively quick, selecting the right lens type is an important decision that will significantly impact your day-to-day vision.
Schedule Laser Cataract Surgery
Before you go home, your surgeon will explain eye drops and activity limits. Many people return for a follow-up visit the day after surgery. Blurry vision, glare, and faded colors are signs of a cataract, and an eye exam can check for them. Contact our office today to schedule your cataract evaluation.
