MAUI, Hawaii — An accommodative IOL from STAAR Surgical may facilitate accommodation following clear lensectomy and cataract extraction, according to Raymond M. Stein, MD.

“The DualFlex was initially developed to treat hyperopic patients who required more power than what was available in a single lens,” Dr. Stein said at Hawaii 2003: the Royal Hawaiian Eye Meeting. Dr. Stein's technique, dubbed the DualFlex, uses two conventional STAAR IOLs piggybacked together in the eye. He combines a STAAR plate-haptic and three-piece IOL, which he says offers patients some accommodation. In a small study, the double implants not only corrected hyperopia, but also appeared to provide an accommodative effect, he said.

The study consisted of 24 eyes of 13 patients. All patients ranged from +5 to +16 D, and all underwent clear lens extraction. After making a 3-mm clear corneal incision and performing standard phaco, the surgeon placed a STAAR Surgical standard silicone plate lens in the capsular bag and STAAR’s three-piece IOL in the sulcus.

Fifteen of the 24 patients (62.5%) had an uncorrected visual acuity of 20/40 or better for distance vision, and 83.3% were J4 or better for near. Additionally, 70.8% could see J3 or better with only distance correction in place. Thirteen patients (54.2%) were 20/40 or better for distance and J4 or better for near.

Near vision correction has remained stable in all patients who received dual lens implants, with an average of 13 months follow-up, Dr. Stein said.

Only one complication occurred. The patient, who does power yoga several times per week and “stands on her head for about an hour a day,” was standing on her head within 1 week postop. Dr. Stein said she was asymptomatic, but she had pupillary capture 7 weeks postop. The lens was repositioned, and the patient is doing well, he said.

Dr. Stein said further study will investigate the optimum power distribution of the IOL in the bag versus the sulcus and if satisfactory results can be achieved in myopic eyes.
