    Top 5 innovations in eye care

    Atlanta—Clark Chang, OD, MSA, MSc, FAAO, recently shared what he considers to be the top-five innovations in eye care during a session at SECO 2016.

    1. Femtosecond laser-assisted cataract surgery

    It’s all about precision and control with femtosecond laser-assisted cataract surgery, says Dr. Chang.

    “Just as we can use femtosecond laser—which is a great, great invention—to assist in kerotoplasty, we can now use femtosecond laser to assist in cataract surgery,” he says. “And because of demographic shifts, you and I are going to be taking care of a lot of cataract patients, so therefore, I think this is one thing that has a lot of impact going forward with regard to patient outcome after cataract surgery.”

    Dr. Chang says that outcomes were already good with the manual cataract extraction method, but manual capsulorhexis can be difficult.  

    “One of the most important things for a successful outcome in a cataract surgery is actually the capsulorhexis—the act of tearing apart the very thin membrane on the anterior capsule, making it as symmetrical—hopefully—as possible,” he says. “The important thing about having a symmetrical capsule is that we know the capsule contracts slightly after an intraocular lens (IOL) is inserted, so the contraction can change the position of the lens, and if it is not done symmetrically, the lens can tilt.”

    Femtosecond laser offers perfect centration, no radial tears, and easy and complete removal of the capsule. Dr. Chang says that because the procedure is more predictable and precise, it has more reproducible outcomes.

    “If a surgeon thinks that automated instruments are going to replace optometrists, I’m going to tell them that lasers are going to replace them—so I’m not afraid,” says Dr. Chang.
