Abstract
BACKGROUND: Evaluation of rotational stability of a microincision intraocular lens with plate haptic design (*Acri. Smart 46S, *Acri.Tec AG) and its centering in the capsular bag after implantation. MATERIAL AND METHOD: In a total of 43 eyes in 37 patients a foldable, spherical microincision cataract surgery (MICS) intraocular lens (IOL) with plate haptic design was implanted through a 1.4-mm microincision by means of an injector system. The IOL was marked prior to implantation to allow exact determination of its endocapsular position. After 1 1/2 years the best corrected visual acuity, refraction, centering and rotational stability of the IOL were determined. RESULTS: No rotation or decentration was observed in any of the 42 eyes 12-19 months postoperatively. On the first postoperative day 1 IOL rotated in the counterclockwise direction by approx. 6 degrees as a result of flattening of the anterior chamber. Its position then remained stable. No unwanted complications occurred. CONCLUSIONS: Conclusions: *Acri. Smart 46S is a safe, effective and stable IOL that can also be used as the basis of complex refractive optical systems, e.g. for correction of astigmatism.
