The accommodating IOL (Crystalens, eyeonics) appears promising in providing pseudophakic patients with enough pseudoaccommodation to function without near glasses, said George I. Papastergiou, MD.
New Orleans-The accommodating IOL (Crystalens, eyeonics) appears promising in providing pseudophakic patients with enough pseudoaccommodation to function without near glasses, said George I. Papastergiou, MD.
He presented data from 83 eyes of 44 patients (ages 42 to 74 years old) who were followed for up to 3 years. At 2 weeks after surgery, all eyes showed excellent IOL centration, none had flare or cells in the anterior chamber, IOP was consistently
At last available follow-up, 100% of eyes had distance UCVA of 20/40 and 88% saw 20/25 or better, although nine eyes underwent LASIK for >1 D of residual myopia.
Near UCVA was J4 or better in 100% of eyes and J3 or better in 93.8%, and all eyes could read J4 or better through distance correction. Accommodative range by defocusing was between 0.75 and 2.0 D and appeared stable throughout the study, averaging 1.65 D at 1 month and 1.48 D at 36 months.
Dr. Papastergiou reported 23 eyes required Nd:YAG capsulotomy. While they initially presented with regression of the accommodative effect, they improved following the capsulotomy with a mean change of 0.22 D.
"We have found high patient satisfaction in this group, although we caution surgeons to be careful in selecting candidates. Since the optic is only 4.5 mm, we implant this accommodating IOL only in eyes with a scotopic pupil
