One-year evaluation of the performance of the Trulign toric intraocular lens implanted in eyes using intraoperative aberrometry to determine sphere, cylinder and position.

Objective: To evaluate the performance of the Trulign toric intraocular lens (IOL) positioned with intraoperative aberrometry in eyes with one year of follow-up.

Design: Masked, retrospective data analysis.

Participants: All patients implanted with a Trulign toric IOL between June 2013 and September 2014.

Methods: All eligible patients underwent phacoemulsification cataract surgery by the same surgeon and were implanted with a Trulign toric IOL (1.25 D, 2.00 D, or 2.75 D). Preoperatively, astigmatism correction was determined by a toric calculator. Intraoperative aberrometry provided real-time data validation and determined final spherical and cylinder power as well as axis of placement. Data were entered in a registry. Postoperatively, uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities (VA), postoperative residual refractive astigmatism (RRA), and best-corrected distance VA (CDVA), were evaluated.

Results: A total of 115 eyes were available for the 1 year visit. All eyes achieved 20/40 or better CDVA. Uncorrected visual acuity of ≥ 20/25 was achieved by 83% of eyes at distance, 95% at intermediate and 81% at near. Mean UDVA was LogMAR 0.06 ± 0.09, UIVA was -0.01 ± 0.09 and UNVA was 0.07 ± 0.08. RRA was ≤ 0.5 D in 98% of eyes and ≤ 1.0 D in 98% of eyes.

Conclusion: The Trulign toric IOL provided good functional vision at distance, intermediate and near with minimal RRA after cataract surgery with guidance provided by intraoperative wavefront aberrometry.
