Local Surgeon First in State to Perform Cataract Eye Surgery with LenSx® Laser


Christopher Shelby, M.D.Christopher Shelby, M.D., with Pierremont Eye Institute and WK Eye Institute, is the first surgeon in Louisiana to perform cataract surgery with Alcon’s LenSx®, a computer-controlled laser that ensures the highest precision surgical incisions. The LenSx® was first used by Dr. Shelby in February at the Eye Surgery Center on the campus of Willis-Knighton Medical Center.

"Laser assisted cataract surgery will greatly enhance our surgical outcomes especially in regards to managing astigmatism,” said Shelby. “I am very excited to be able to offer my patients the most advanced and precise cataract surgery in the world. Having the only LenSx system in Louisiana, has placed Willis-Knighton as the premier eye center for cataract surgery."

LenSx® utilizes focused femtosecond laser pulses to create precise incisions in the lens capsule, lens and cornea. A femtosecond is the unit of time equal to 10-15 of a second that is one quadrillionth or one millionth of one billionth of a second.

The laser provides a more precise circular incision around the cataract and improves the accuracy during placement of the intraocular lens implant which leads to clearer vision. The main corneal incision is created through multiple planes to prevent potential wound leakage. A real-time laser imaging system guides the laser beam to the correct target during the surgery

The laser pre-softens the cataract, allowing surgeons to minimize the use of ultrasound energy to remove the cataract lens. Decreased usage of ultrasound energy reduces the chances of thermal injury to tissues in the eye.

Astigmatism correction also can be done in the same setting using the LenSx® and this may lessen the patients need for glasses.
