Capsular Tension Ring Implantation Linked to Improved Intraocular Lens Stability

MONDAY, June 23, 2025 (HealthDay News) — Capsular tension ring (CTR) implantation is associated with improved stability of the intraocular lens (IOL), according to a review published online June 12 in JAMA Ophthalmology.

Haowen Lin, M.D., from Sun Yat-sen University in Guangzhou, China, and colleagues examined the association of CTR implantation on IOL position in a systematic review and meta-analysis that included 11 randomized clinical trials and seven cohort studies, with 809 eyes with CTR and 822 eyes without CTR.

The researchers found that compared with the control group, the IOL tilt and rotation were smaller in the CTR group (mean difference, −1.04 and −0.82 degrees, respectively). Heterogeneity between the subgroups stratified according to IOL haptic design was seen in the subgroup analysis of anterior chamber depth, decentration, and tilt. In addition, compared with the control group, the CTR group showed a deeper anterior chamber depth in eyes implanted with plate haptic IOLs (mean difference, 0.11 mm) and a smaller IOL tilt in highly myopic eyes (mean difference, −1.43 degrees).

“These findings support the use of CTR implantation when toric IOLs have been implanted or in cases of high myopia,” the authors write. “The clinical relevance of these findings merits further investigation.”
