Laser Cataract Surgery (SSME-04)
The Challenge

Cataract surgery is the most commonly performed surgical procedure in the world. Recent advancements have introduced femtosecond laser–assisted technology as a potential way to improve safety, accuracy and clinical outcomes. To implement this new technology in a new laser surgery system, the customer needed a small, reliable and field proven optical encoder with enough resolution and accuracy to focus the 3 micron spot size in exactly the right location.

The Solution

Celera Motion worked closely with the customer to help narrow down their requirements and ultimately selected the MicroE Mercury 1500 Series encoder and small linear glass scales. Mercury Model M1500H is an RS-422 compatible with a miniature 5x2 micro-connector. Its industry leading small sensor size and wide alignment tolerances made it the ideal choice for the compact working area in the customer’s new laser surgery system.

The Benefit

After receiving its FDA approval, the customer’s new laser surgery system has become one of the most popular solutions for laser cataract surgery on the market today, providing new levels of safety and accuracy and delivering excellent patient outcomes.
