Summary
Hydrophobic C-loop toric intraocular lenses (IOLs) demonstrate superior early rotational stability compared to hydrophilic plate-haptic IOLs. Platform-specific biometric factors influence rotation, guiding individualized IOL selection and monitoring.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Medical Optics
Background:
- Toric intraocular lenses (IOLs) correct astigmatism during cataract surgery.
- Rotational stability is crucial for effective astigmatism correction.
- Different toric IOL designs may exhibit varying degrees of rotational stability.
Purpose of the Study:
- To compare the postoperative rotational stability of three distinct toric IOL platforms.
- To identify specific biometric factors linked to toric IOL rotation within each platform.
Main Methods:
- A prospective multicenter randomized controlled trial involving 256 eyes across three Chinese eye centers.
- Patients received either TECNIS Toric II, Clareon Toric, or AT TORBI 709M IOLs.
- Rotational alignment was assessed postoperatively up to 3 months.
Main Results:
- Hydrophobic C-loop IOLs (ZCU and CNW0T) achieved stability faster (1 week) than the hydrophilic plate-haptic IOL (709, 2-4 weeks).
- The AT TORBI 709M exhibited greater rotation (12.2% ≥10°) than Clareon Toric (2.4%) and TECNIS Toric II (1.2%).
- White-to-white distance and lens thickness were associated with increased rotation in specific IOL groups.
Conclusions:
- Hydrophobic C-loop toric IOLs offer enhanced early rotational stability over hydrophilic plate-haptic designs.
- Biometric factors influencing rotation vary by IOL platform, necessitating personalized selection and monitoring.
