Toric Lens With Modified Haptic Design Shows Outcomes Comparable With Predecessors

Researchers investigate the visual performance and rotational stability of a new toric intraocular lens with modified haptic design.

This article is part of Ophthalmology Advisor’s conference coverage from the 2021 meeting of American Society of Cataract and Refractive Surgery (ASCRS), held in Las Vegas from July 23 to 27, 2021. The team at Ophthalmology Advisor will be reporting on a variety of research presented by the cataract and refractive surgery experts at ASCRS. Check back for more from the ASCRS 2021 Meeting.


Research shows a new toric intraocular lens, the Tecnis® Toric II Optiblue (Johnson & Johnson Vision,) with a modified haptic design has similar rotational stability and visual performance as the Acrysof IQ® Toric (Alcon). These findings were presented during the American Society of Cataract and Refractive Surgery (ASCRS) annual meeting held July 23 to 27, in Las Vegas.

Patients (N=100) with corneal astigmatism >0.75 D who were expected to have postoperative uncorrected visual acuity of ≥0.1 logMAR were recruited for this prospective, observational comparative study. Patients received either the Tecnis Toric II Optiblue (n=50) or the Acrysof IQ Toric implant (n=50). Researchers evaluated the efficacy at 1 day, 1 week, 1 month, and 3 months after implantation. The study took into account the intraocular lens alignment as well as the patients’ visual acuities and residual astigmatism.

At 3-months after implantation, patients who received the Optiblue and Acrysof implants had alignments of 1.52±2.16 ° and 2.17±2.42 °, respectively. The uncorrected distance visual acuities were -0.13±0.074 for the Tecnis Toric II Optiblue and -0.090±0.123 for the Acrysof IQ Toric. The corrected distance visual acuities were -0.075±0.022 and -0.053±0.064, and their residual subjective astigmatisms were 0.19±0.30 D and 0.13±0.25 D, respectively. No significant group differences were observed.

The postoperative prediction error in astigmatism was 0.17 D@139°±0.32 D centroid for the Tecnis Toric II Optiblue and 0.05 D@127°±0.28 D centroid for the Acrysof IQ Toric.

This study was limited by its small sample size and short follow-up duration. These results require external validation, and it remains unclear whether long-term performance of the 2 toric intraocular lens products remain similar.

The study authors report that the Tecnis Toric II Optiblue and the Acrysof IQ Toric had comparable alignment, visual acuity, and residual astigmatism outcomes at 3 months. These data suggested there was no significant difference in either rotational stability or visual performance between the 2 implants.
