Mixing lenses may enhance refractive performances

NEW YORK — Paired and matched presbyopic lens exchange technologies are not sufficient to satisfy all optical needs, but mixing presbyopia-correcting lenses can significantly enhance postoperative performance, according to a surgeon speaking here.
Because the patient population is aging and starting to experience visual problems, baby boomers are going to expect the same type of outcomes from lens-based refractive surgery that they have seen for the past decade with LASIK, said J. Trevor Woodhams, MD, at the OSN New York meeting.
"That means the ante is up and we need to deliver that level of correction," he said.
Dr. Woodhams said surgeons today are looking for an ideal IOL that is minimally affected by different lighting conditions and offers crisp resolution, excellent distance acuity, variable magnification and performance that does not depend on pupil size.
"The crystalens (eyeonics) gives excellent distance vision night to day," he said. "The ReSTOR (Alcon) also provides excellent vision, especially in the daytime, and the aspheric is even better."
However, determining a patient's worst complaint is the biggest variable when considering mixing lenses, he noted.
