Enhanced Intraocular Lens Stability Through Capsular Tension Ring Implantation

Recent research published in JAMA Ophthalmology highlights the benefits of capsular tension ring (CTR) implantation in improving the stability of intraocular lenses (IOLs) following eye surgeries. A comprehensive systematic review and meta-analysis conducted by Dr. Haowen Lin and colleagues from Sun Yat-sen University in Guangzhou examined data from 11 randomized clinical trials and seven cohort studies, encompassing 809 eyes with CTR and 822 eyes without CTR. The findings revealed that eyes with CTR experienced significantly less IOL tilt and rotation—specifically, reductions of approximately 1.04 and 0.82 degrees, respectively—compared to controls. The analysis also showed that in eyes implanted with plate haptic IOLs, the anterior chamber depth was slightly deeper (by about 0.11 mm), and highly myopic eyes with CTR had reduced IOL tilt (by 1.43 degrees). These results suggest that incorporating CTR during procedures, especially in cases involving high myopia or toric IOL implantation, can enhance lens stability. However, the authors emphasize that further clinical investigations are needed to fully understand the practical implications of these findings. Overall, this evidence supports the use of capsular tension rings to optimize intraocular lens positioning and potentially improve surgical outcomes.
