Cataract surgery with implantation of a mechanically and reversibly adjustable intraocular lens: *Acri.Tec AR-1 posterior chamber intraocular lens.

I f it were possible to adjust the refraction of a pseudophakic eye by means of an adjustable posterior chamber intraocular lens (PC/IOL), subjective comfort or visual function would be improved. This is especially true in children. Several approaches to create an adjustable intraocular lens (IOL) are currently under study. This field is still in an early stage of its evolution. The *Acri.Tec AR-1 PC/IOL (*Acri.Tec, Hennigsdorf, Germany) is a mechanically and reversibly adjustable PC/IOL, which has been implanted and adjusted in adult human eyes. So far the results after short-term follow-up of the initial cohort suggest that the use of this PC/IOL would be safe. Through continued observation of the eyes from this cohort we have tried to determine the long-term safety of this PC/IOL, behavior of the PC/IOL after Nd:YAG laser capsulotomy, and refractive stability of the eyes.
