Abstract Details

Purpose:

To evaluate the efficacy of transscleral suture fixation of capsular tension ring (CTR) in providing additional support during and/or after phacoemulsification in cases of a weak or partially broken ciliary zonule. Modern surgical approaches of subluxated cataract in presence of zonular weakness involves placement of capsular tension ring (CTR) that reduces iatrogenic loss of zonular support and prevents complications during phacoemulsification. Placement CTR also prevents possible further complications, as macular edema after cataract surgery, late spontaneous IOL-capsular bag complex dislocation, capsular contraction syndrome and secondary glaucoma due to a pseudophacodenesis and progressive zonular rupture.

Setting:

Clinic of Eye Microsurgery “Glaz”, Ekaterinburg, Russia, clinicaglaz@mail.ru

Methods:

Standard CTR were placed and transscleral fixed by suture(s) after performing continuous circular capsulorhexis, before phacoemulsification by our original methodic in patients who were found to have a weakened or partially broken ciliary zonule. Posterior chamber intraocular lens (PCIOL) were implanted into capsular bag and transsclerally sutured if need, for stable centration in the postoperative period. Patients were examined preoperatively, intraoperatively, and postoperatively at months 1, 3, 6, and 12.

Results:

Results indicate that next day after surgery and a month after 98,2% of IOLs were in centered position and there was no pseudophacodenesis. 5,4% patient had macular edema. The number of slightly decentered IOLs was 3,6% 3 months after surgery and 6 months after surgery, and 5,4% 12 months after surgery. Posterior capsular opacification was in 12.6% of eyes by 12 months and was treated by YAG-capsulotomy.

Conclusions:

Transscleral suture fixation of capsular tension ring (CTR) before phacoemulsification provide additional support during and/or after phacoemulsification in cases of zonular dehiscence and to ensure a stable position of the IOL and capsular bag and to reduce the risk of complications, such as late spontaneous IOL-capsular bag complex dislocation, capsular contraction syndrome and secondary glaucoma.
