Purpose:
This study aims to evaluate rotational stability and patient-reported outcomes associated with Tecnis Eyhance toric II "monofocal plus" intraocular lens (IOL), particularly in light of a modified haptic design.
Methods:
A prospective, interventional study was conducted with patients undergoing routine cataract surgery and Tecnis Eyhance toric II IOL implantation. The inclusion criteria were topographic corneal astigmatism of 0.5-4.0D. Exclusion criteria included previous corneal or ocular surgeries, mesopic pupils >5.5mm, wear of rigid gas-permeable contact lenses, and ophthalmic pathologies that might limit vision outcomes. Toric stability was assessed on day 1, week 1, and month 3 using slit-lamp exams and toriCAM app. Quality of Vision (QoV) and Near Activity Visual Questionnaires (NAVQ) before the surgery and 3 months post-operatively.
Results:
The study analyzed 98 eyes from 65 patients. Mean absolute IOL rotation was 1.73±1.64° (range: 0-7°) from day 1 to week 1, with 95% rotating ≤5°. From week 1 to month 3, mean rotation was 1.13±1.53° (range: 0-8°), with 98% rotating ≤5°.
Conclusion:
The data from this study suggest that the Tecnis Eyhance toric II IOL exhibits good postoperative rotational stability and positive patient-reported visual outcomes.
