Accommodative dual-IOL technique shows promise for presbyopes

NEW YORK — A technique that uses two IOLs to achieve pseudoaccommodation is showing promise for presbyopes, according to a surgeon speaking here.
Raymond Stein, MD, presented preliminary findings on his technique here at the Eleventh Annual Ocular Surgery News New York Symposium on Cataract, Glaucoma, Retina and Refractive Surgery.
Dr. Stein's technique, which he has termed "Dual-Flex," employs two standard STAAR IOLs, the Elastic and the Elastamide. (STAAR does not manufacture an accommodative IOL system.)
Dr. Stein's technique was developed for use with clear lensectomy in hyperopic patients. Two lenses are inserted. A plate-haptic IOL, inserted in the capsular bag, makes up two-thirds of the total lens power. A three-piece silicone IOL, inserted in the sulcus, makes up the remaining one-third of the lens power. Dr. Stein said this technique improves both distance and near vision.
The double-lens technique was used in 24 eyes of 13 patients. Mean patient age was 53 years. Average preoperative spherical equivalent was +8.6 D, and average follow-up was 13 months. Fifteen of 24 eyes (63%) were 20/40 or better uncorrected for distance, and 83% had J4 or better uncorrected near vision, Dr. Stein said. Additionally, 83% could see J4 or better and 71% could see J3 or better with distance correction in place.
None of the patients lost best corrected visual acuity, Dr. Stein said. Only one eye experienced a complication, pupillary capture.
