    In the pipeline: What’s new and what’s coming in optometry technology

     

    Dry eye testing

    “The future is non-invasive dry eye testing,” says Dr. Karpecki. “Tear break-up time will become non-invasive.”

    Allergan’s TruTear technology, which was recently approved by the FDA, stimulates tears to help treat aqueous deficient dry eye. TruTear is inserted through the nasal canal and uses wireless stimuli to create tears.

    True Tear uses electrical impulses to stimulate the trigeminal nerve and produce natural tears. Trigeminal nerve stimulus creates meibum, mucin, and tears.

    When treating dry eye, Dr. Karpecki warns that you can’t just do one thing and see success.

    “You can’t do one thing for the most common form of dry eye, evaporative dry eye,” he says.  “You have to treat all four: Obstruction, inflammation, tear film, and biofilm.”

    The other problem ODs see with dry eye patients is symptoms due to digital device usage and blink rate.

    “The average person blinks 15 to 20 times per minute in conversation,” says Karpecki. “The average times they blink while using a digital device is four.”

    Another option is Dr. i-Coach, The Dr. i-Coach is a sensor and software package that can help users develop and maintain proper computer habits by incorporating the recommended treatment philosophies and recommendations from key eye care professionals and organizations

    Migranes and eyegraines

    Some patients have trouble battling migraines, or as some call them “eyegraines.” NueroLens is a therapeutic lens developed to help realign the eyes and reduce headaches in patients. In the test study, 74 percent of patients reduced their headaches and dry eye, according to Dr. Karpecki.

    NeuroLens is a progressive prism lens and will hit the market in late 2017.

    Tonometer

    Icare ic100  measures intraocular pressure using a patented rebound measuring principle that requires no air, drops, or specialized skills for its use. Icare's proprietary algorithm coupled with its software allows it to evaluate deceleration, contact time, and other motion parameters of the probe when it touches the cornea.

    3D printing

    Though still in its infancy, 3D printing offers hope for optical reconstructive surgery, according to Dr. Karpecki. Researchers have produced a 3D eye socket for reconstructive surgery. 3D printing also allows doctors to use implants with finishes that will encourage the bones to meld with the implant. 3D implants tend to fit better than traditional metal implants and may shorten surgery and recovery times

    Ophthalmic lenses

    Katena has developed a line of reusable and single-use ophthalmic lenses. These lenses were designed to help lower costs and minimize risk of disease transmission. The lenses arrive sterile, so there is no need to clean and disinfect the lens prior to use.
