COPENHAGEN — Capsular tension rings used during cataract surgery improved refractive outcomes in high myopes, according to a study presented here.
The retrospective case review compared refractive outcomes in highly myopic patients undergoing routine cataract surgery with and without capsular tension rings in place during the procedure.

Indications for capsular tension ring use in high myopes undergoing cataract surgery include zonulysis or weakness, and there is mixed evidence that their use helps prevent anterior capsule contraction syndrome and reduce posterior capsule opacification, Haneen Jasim, MD, said at the European Society of Cataract and Refractive Surgeons meeting. In this study, patient data for the capsular tension ring group were culled from a 10-year period at a single practice where capsular tension rings were used routinely in high myopes undergoing cataract surgery.
Overall, 244 eyes with an IOL implant measurement of 15 D or less were included. The capsular tension ring group had 140 eyes, and the non-capsular tension ring group had 104 eyes.
“When we compare the mean absolute error, which is the difference between predicted refraction and achieved spherical equivalent, we find that the capsular tension ring group had a smaller refractive error with a narrower standard deviation, and this difference was significant,” Jasim said. “We also find that the capsular tension ring group is more likely to achieve low refractive error and less likely to have refractive surprise.” – by Patricia Nale, ELS
