Laser Cataract Surgery

Traditional vs Laser-assisted Cataract Surgery

In the past, surgeons would make many steps of cataract surgery with a manual hand-held blade and hand-held instruments. These steps included the incisions for instruments to enter the eye, the capsulorhexis (opening made into the bag that holds the lens of the eye) and limbal relaxing incisions for reducing astigmatism.

With laser-assisted cataract surgery, many of these steps are now performed with the precision of a computer-guided femtosecond laser. This new method of performing cataract surgery can make the procedure more precise, more predictable and better than ever before.

Sweeney Eye Associates
Now Offers Laser Cataract Surgery with CATALYS®

Sweeney Eye Associates is the first practice in the Dallas area to offer patients the new standard in precision cataract surgery with the CATALYS® Precision Laser System. Using CATALYS, With this technology, the surgeons of Sweeney Eye Associates can provide a gentle, highly customized cataract procedure with precision not achievable with traditional manual techniques

What is CATALYS?

Developed by Silicon Valley-based OptiMedica Corp., CATALYS is a new FDA market cleared medical device that features a state-of-the-art laser, advanced 3D imaging, and many other innovative features that can bring numerous benefits to patients.

How does it work and what are the steps?

Every eye has a unique size and shape. CATALYS’ advanced 3D imaging technology builds a 3D map of each eye and tailors the treatment to that map. This enables Sweeney Eye Associates surgeons to create a customized treatment plan that matches the uniqueness of each eye.

Next, Sweeney Eye Associates surgeons use CATALYS to create a circular opening for accessing and removing the cataract. Clinical studies have shown that this opening is approximately 10 times more accurate when performed with CATALYS than what is achievable by hand.1,2 CATALYS then softens and breaks up the hard cataract into tiny pieces, allowing for gentler, easier cataract removal.
Depending on the patient’s pre-operative vision and desired visual result, Sweeney Eye Associates surgeons may recommend a tailored treatment plan that could include creating ultra-precise laser incisions in the cornea and a specific clear lens type, such as a multi-focal lens. This tailored treatment may reduce a patient’s need for glasses or contacts after surgery.

What are the benefits of CATALYS?

  • A highly customized procedure using advanced 3D imaging
  • A treatment with little or no discomfort
  • A more precise treatment
  • A gentler and easier cataract removal
  • Generally, a more rapid visual recovery due to reduced inflammation
  • The opportunity to receive tailored treatment with advanced technology multi-focal lenses, which may reduce the need for glasses or contacts after surgery
