Purpose To investigate long‐term safety and function of a mechanically, reversibly adjustable intraocular lens in human eyes Methods Clinical long‐term monitoring of the initial 38 eyes of 38 patients with senile cataract after implantation of the *Acri.Tec AR‐1 PC/IOL including a control group. Results Median follow‐up was 25 (range 6 to 52 months). Throughout the entire period of observation all eyes were behaving clinically in the same way as if implanted with a conventionel PC/IOL. 2 eyes were adjusted surgically 2 weeks after implantation. 19/38 eyes underwent Nd:YAG laser capsulotomy after a median period of 12 (range 6 to 43) months after implantation. Median change of spherical equivalent between 1 month and the last visit was 0 (range – 0.5 to + 0.5) diopters. At the last visit median best visual acuity was 0.7 (range 0.2 to 1.0) for eyes with the *Acri.Tec AR‐1 PC/IOL and 0.8( range 0.3 to 1.0) for the control group. Both eyes having undergone adjustment surgery had visual acuity of 0.8 rsp 1.0 with stable refractions 45 rsp. 42 months after adjustment surgery. Conclusion The *Acri.Tec AR‐1 PC/IOL implanted into the capsular bag of adult human eyes is a safe PC/IOL. Refraction is predictably adjustable after implantation. It remains stable before and after Nd:YAG laser capsulotomy or after surgical adjustment of the refraction. This type of IOL may prove helpful especially in pediatric cataract surgery to avoid the development of amblyopia and in adults when precise refractive outcome is important either because of individual preference of the patient for a preferred refraction or because of intendend monovision to reduce spectacle dependence to a minimum.Commercial interest
