This systematic review and meta-analysis evaluated the impact of capsular tension ring (CTR) implantation on the rotational stability of intraocular lenses (IOLs) in 1251 eyes. The study found that CTR implantation did not significantly reduce mean IOL rotation (MD -0.40 degrees; p = .322), but it may reduce IOL misalignment, particularly for loop-haptic IOLs, with significant findings in subgroup analyses.

Key findings

  • CTR implantation did not significantly reduce mean IOL rotation (MD -0.40 degrees; p = .322).
  • No significant differences in IOL rotation exceeding 5 degrees (p = .150), 10 degrees (p = .065), or 15 degrees (p = .176).
  • CTR significantly reduced misalignment for loop-haptic IOLs (MD -1.25 degrees; p < .001).
  • The proportion of IOL misalignment exceeding 5 degrees was significantly lower in the CTR group (RR 0.53; p = .018).

Why it matters

Understanding the effects of CTR implantation on IOL stability is crucial for optimizing surgical outcomes in cataract surgery. This research highlights the potential benefits of CTR in reducing misalignment, which can impact visual outcomes.
