Johnson & Johnson Vision wins FDA nod for iDesign Lasik device
Johnson & Johnson (NYSE:JNJ) Vision said today that the FDA approved its iDesign Refractive Studio for planning Lasik eye procedures.
iDesign uses a three-second scan to perform a wavefront analysis of how light travels inside the eye and maps the topography of the cornea to customize Lasik treatments for myopia, hyperopia, mixed astigmatism and presbyopic myopia, Santa Ana, Calif.-based J&J Vision said.
“As a practicing ophthalmologist for more than 25 years, I know firsthand the importance of taking precise measurements and tailoring Lasik procedures for each patient,” medical & clinical affairs ...

Columbia engineers invent a noninvasive technique to correct vision
(Columbia University School of Engineering and Applied Science) Columbia engineers have developed a noninvasive approach to permanently correct vision that shows great promise in preclinical models. The method uses a femtosecond oscillator for selective and localized alteration of the biochemical and biomechanical properties of corneal tissue. The technique, which changes the tissue's macroscopic geometry, is non-surgical and has fewer side effects and limitations than those seen in refractive surgeries. The study could lead to treatment for myopia, hyperopia, astigmatism, and irregular astigmatism. (Source: EurekAlert! - Biology)

FDA Clears Way For First Contact Lenses With Light-Adaptive Technology
BOSTON (CBS) – More than 40-million Americans wear contact lenses and today the FDA cleared the way for the first contact lens with light-adaptive technology.
The Johnson & Johnson’s ACUVUE OASYS soft lenses darken when exposed to light similar to eyeglasses that do the same. The lenses contain an additive that changes the degree of light filtered to the eye based on the amount of UV light exposure.
A clinical study found the lenses do not interfere with vision or driving performance.
They can be used in people who are nearsighted or farsighted and even with a certain degree of astigmatism, an abnormal curvatur...

RxSight wins FDA nod for light-adjustable IOL
The FDA has cleared RxSight‘s implantable light adjustable intraocular lens and light delivery device.
The company’s RxSight IOL is designed from a UV light reactive material meant to be treated by a specific Light Delivery Device, intended for use 17 to 21 days post-procedure.
The lens is designed to be treated by 3-4 light treatments over 1 to 2 weeks in 40 to 150 second treatment periods, during which the patient must wear UV-protective glasses.
“Until now, refractive errors that are common following cataract surgery could only be corrected with glasses, contact lenses or refractive surgery. This syste...

KC eye doc: New LASIK procedure could grow patient base
Dr. John Doane said a growing number of patients are coming to his office for a new surgical alternative to LASIK.
Recently approved by the Food and Drug Administration (FDA) to treat nearsighted patients, small incision lenticule extraction (SMILE) makes a tiny incision in the outer cornea, for a shorter recovery time and fewer dry-eye side effects.
Doane participated in a clinical trial starting in 2013 and expects it will be approved to treat astigmatism in mid-2018. An opthalmologist at Discover… (Source: bizjournals.com Health Care:Biotechnology headlines)
