Inter-Visit Rotational Stability Of A Toric Intraocular Lens With Frosted Haptics

 The purpose of this study was to evaluate the inter-visit rotational stability of eyes implanted with the TECNIS Toric II IOL (Models, ZCU 1.50 to 6.0 D) with a frosted haptic design.

Prospective, multi-center, single-arm, open-label study. Seven surgeons from 7 sites implanted the IOL in 202 eyes of 125 subjects. Objective IOL axis alignment was evaluated with photographs obtained at the operative and postoperative visits using a novel validated technique. Inter-visit rotational stability was assessed by calculating the difference in IOL axis between two consecutive visits.

Between the 1-day and 1-week postoperative visits, 95% of eyes had ≤ 2° of lens rotation (mean rotation of 0.85°). Between the 1-week and 3-month postoperative visits, 91% of eyes had ≤ 2° of lens rotation (mean rotation of 0.94°). Mean residual astigmatism (SD) at 1-week and 3-month postoperative visits were 0.30 diopters (0.35) and 0.27 (0.33), respectively. Mean UCDVA (SD) at 1-week and 3-month postoperative visits were 0.03 (0.14) and 0.00 (0.12), respectively. Mean BCDVA (SD) at 1-week and 3-month postoperative visits were -0.06 (0.10) and -0.07 (0.09), respectively.

The TECNIS Toric II IOL with frosted haptic design demonstrates excellent inter-visit rotational stability, low and stable residual astigmatism, as well as good and stable UCDVA and BCDVA.
