    Extended-depth-of-focus IOLs expand surgical options

    Point/counterpoint among surgeons examines IOL benefits, compares with existing lenses

    Take-home message: Surgeons share their lessons learned about new lens technologies for refractive cataract surgery, such as extended-depth-of-focus IOLs.



    Visual quality, depth of field, and night vision are three factors that come into play with premium IOL use—and each IOL choice may offer benefits with some of these factors but not others. Traditional presbyopia IOLs may increase depth of field, but they can decrease visual quality and nighttime vision.

    With extended-depth-of-focus IOLs, there may be fewer sacrifices, said Daniel H. Chang, MD.

    “Extended-depth-of-focus IOLs, which provide at least an additional 0.5 D of focus at 20/30, achieve a new set of compromises, and expand the options for surgeons to treat presbyopia,” said Dr. Chang, Empire Eyea and Laser Center, Bakersfield, CA.

    This particular kind of IOL class appears to have fewer problems with glare and halos as well.

    A paper published last year from the FDA and the American Academy of Ophthalmology took into account information from 200 stakeholders to try and pinpoint quality requirements for this type of IOL,1 Dr. Chang said.

    The use of extended-depth-of-focus IOLs gives surgeons one more option for patients as they aim for better visual acuity in today’s patients, Dr. Chang said.

    “Refractive cataract surgery addresses cataracts and refractive errors,” he said. “Not treating ametropia and presbyopia is not an option.”
