“…Mean absolute lens rotation was less than 1° at both the 1-day and 1-week visits, which was less than previously reported for the TECNIS Toric IOL (1° to 8.38°), 4 , 9 , 10 , 12 , 17–19 confirming that the squared and frosted haptic design improved rotational stability. These data compared favorably with absolute rotation reported for other toric IOL models, including with the AcrySof Toric IOL (Alcon Laboratories, Inc., Fort Worth, TX, USA) (1.5° to 8.0°), 5 , 9 , 18 , 20–24 the enVista Toric IOL (Bausch+Lomb, Inc. Rochester, NY, USA) (1.11° to 3.85°), 25 , 26 and the HOYA XY-1 (HOYA, Tokyo, Japan) (5.43°). 18 …”

“… 14 , 27 The HOYA 355 toric IOL (HOYA, Tokyo, Japan) was recently modified to the HOYA XY-1 toric IOL model, which included design changes such as introducing texture to the haptic surface and increasing the overall length. 18 Osawa et al reported significantly reduced axis misalignment at 1-day with the HOYA XY-1 toric IOL (5.43° ± 4.67°) compared to the HOYA 355 (8.78° ± 6.54°). Presumably, the increased friction from the textured haptic contributed to this reduction.…”

Purpose To evaluate the reproducibility of magnitude of postoperative IOL rotation following implantation of a toric intraocular lens (IOL) with modified haptics, in comparison with a Proof-of-Concept (POC) study of prototype IOLs featuring the same haptic design. Patients and Methods A post-market, prospective, multicenter, single-arm, open-label clinical study was conducted. TECNIS Toric II IOL (Johnson & Johnson Vision, Irvine, CA, USA, Models ZCU150 to 600) were implanted in 125 subjects and evaluated at 1-day and 1-week postoperatively. An objective photographic method was used to determine postoperative IOL rotation. Uncorrected distance visual acuity (UCDVA), postoperative astigmatism, and surgeon satisfaction were also assessed. Rotation data were compared to the POC study in which two prototype non-toric monofocal IOLs, one with the same haptic design as Model ZCU, were studied. Results Mean absolute rotation was 0.82° ± 1.0° and 0.84° ± 0.92°at 1-day and 1-week visits, respectively. The percentage of eyes with ≤5° of absolute rotation was 98.9% and 99.5% at the 1-day and 1-week visits, respectively. The magnitude of rotation was similar to the POC study prototype IOLs. At 1-week, mean monocular UCDVA was 0.026 ± 0.135 (~20/21) logMAR and mean residual manifest refractive cylinder was 0.30 D ± 0.35 D. The mean signed axis difference (postoperative minus operative) of the TECNIS Toric II IOL was 0.23° ± 1.27° at 1-day and −0.07° ± 1.25° at 1-week, indicating a clockwise drift. At 1-week, surgeons were very satisfied or satisfied with overall clinical outcomes and rotational stability in 98% of implanted eyes. Conclusion The TECNIS Toric II IOL, with frosted, squared haptics, demonstrated low magnitude of postoperative IOL rotation, excellent uncorrected distance vision, and minimal residual astigmatism. The POC study design was supported, demonstrating that prototype non-toric monofocal IOLs can predict clinical performance of toric IOLs with the same haptic design.

“…Previous studies demonstrated that postoperative rotational stability varies across different model of toric IOLs 2 – 7 , indicating that the design, material, and surface finish of the IOL, especially haptics, should be among the important factors affecting postoperative rotational stability of toric IOLs. One study revealed that modification of the haptics of a toric IOL, by increasing overall length, reducing unfolding time, and introducing texture processing to the surface of haptics, significantly reduced postoperative axis misalignment 8 .…”

We investigated the unfolding property and rotational stability of a new toric intraocular lens (IOL); TECNIS toric II (toric-II, ZCW, Johnson & Johnson) that is an improved version of TECNIS toric IOL (toric-I, ZCV). Both IOLs are based on an identical platform, except for the frosted haptics with toric-II IOL. The study consisted of two parts; experimental study and clinical, retrospective, case series. Experimental study indicated that the overall time from IOL ejection to unfolding to 11 mm was significantly shorter with toricII than toric-I IOLs (p = 0.032), due to the earlier separation of the haptics from the optic with toric-II IOL. Clinical study included 131 eyes of 99 patients who had undergone phacoemulsification and toric IOL implantation. At 3 months postoperatively, toric-II IOL showed significantly better rotational stability than toric-I IOL, including smaller residual manifest astigmatism (p = 0.018), less amount of axis misalignment from the intended axis (p = 0.04), lower incidence of misalignment > 10º (p = 0.0044), and less degree of prediction errors (p = 0.043). Postoperative uncorrected distance visual acuity tended to be better in the toric-II than in the toric-I groups, with marginal statistical difference (p = 0.057). TECNIS toric II IOL with the frosted haptics showed significantly better rotational stability than its predecessor, probably due to quicker unfolding and greater friction with the capsular bag.
