    Add-on sulcus-based IOL addresses ametropia post-cataract surgery

    Findings suggest concept is safe, cost-effective alternative to current procedures



    Kenneth J. Rosenthal, MD, explains the advantages of an add-on sulcus-based IOL for correcting refractive errors in eyes that have undergone cataract surgery with in-the-bag IOL implantation.


    Great Neck, NY—A review of reports in the published literature together with an analytical review of design features and personal clinical experience supports the use of an add-on sulcus-based IOL (Sulcoflex, Rayner) as a better option than IOL piggybacking using conventional “in-the-bag” IOLs for correction of refractive problems following cataract surgery, said Kenneth J. Rosenthal, MD, associate professor of ophthalmology at University of Utah Medical School, and in private practice in New York, in a scientific paper co-authored by Jacob Gohari, BA.

    Although not approved by the FDA, the add-on sulcus-based IOL is available in many countries and Dr. Rosenthal has used it at his center, Rosenthal Eye Surgery, Great Neck, NY, and at New York Eye and Ear Infirmary, New York, through an FDA compassionate use device exemptions.

    “There are currently no IOLs approved by the FDA which are designed for implantation in the sulcus, and piggybacking of posterior chamber IOLs in the sulcus can cause a variety of complications, including pigmentary dispersion syndrome, elevated IOP, interlenticular opacification, and IOL decentration or tilt that can ultimately result in visual field loss and decreased visual acuity,” Dr. Rosenthal said.

    “The concept of the add-on sulcus-based IOL is validated by a number of peer-reviewed studies,” he added. “It produces stable, predictable outcomes and avoids or mitigates the problems seen with piggybacking conventional IOLs. Considering some of its benefits, perhaps the sulcus will be the place we put all IOLs in the future.”

    He pointed out that historically the sulcus was used for IOL implantation, but that surgeons migrated to capsular bag fixation due to better centration of the IOL and better sequestration of the IOL from uveal tissue.
