    Laser vision correction effective for residual refractive error after RLE

    Myopic corrections, wavefront-guided LASIK more likely to result in 20/20 UCDA

    Take-home message: Researchers explore the efficacy and reliability of laser vision correction for the treatment of residual refractive error after refractive lens exchange.

     

    San Diego—Both LASIK and PRK are safe and effective procedures to treat residual refractive error following refractive lens exchange (RLE), according to a multisite, international study.

    The study also suggested a preference to perform LASIK for residual hyperopia and PRK for myopia, said senior author Steve Schallhorn, MD.

    “This large sample—larger than previous reports—showed that laser vision correction after implantation of a premium IOL is safe and effective and can improve unaided vision,” said Dr. Schallhorn, clinical professor of ophthalmology, University of California San Diego School of Medicine and chief medical director for Optical Express.

    LASIK is the preferred procedure for faster visual recovery, as more patients attained 20/20 vision in the early postoperative time period.  However, PRK has multiple advantages, including not needing pressure-raising suction for the flap creation. PRK is also a simpler procedure to perform, he noted.

    Both LASIK and PRK have similar long-term outcomes and both carry the possibility of dry eye side effect symptoms.

    Patients who receive a premium IOL tend to have higher expectations than patients receiving a standard monofocal IOL following cataract surgery, Dr. Schallhorn said.

    Goal of emmetropia

    Presuming that emmetropia is the target, the closer postoperative refractive error is to zero, and the higher patient satisfaction and the fewer and less intrusive the patient’s visual symptoms.
