Abstract Details


To report the indications and clinical outcomes of capsular tension ring (CTR) implantations in the consecutive cataract surgeries performed at a private clinic over a fourteen-year period.


Entani Eye Clinic, Hyogo, Japan.


This retrospective study included 200 eyes of 173 patients who had cataract surgery with CTR implantation in 23,903 surgeries performed at a single private clinic from January 2002 to December 2015. CTRs were implanted with or without capsule retractors. The indications and clinical outcomes of CTR implantation were evaluated.


The indications were pseudoexfoliation syndrome (66 eyes, 33.0%), shallow anterior chamber (26 eyes, 13.0%), laser iridotomy (24 eyes, 12.0%), weak zonule (24 eyes, 12.0%), trauma (17 eyes, 8.5%), phacodonesis (16 eyes, 8.0%), zonular rupture (12 eyes, 6.0%), atopic dermatitis (9 eyes, 4.5%), retinitis pigmentosa (3 eyes, 1.5%), high myopia (1 eye, 0.5%), vitrectomy (1 eye, 0.5%), and mature cataract (1 eye, 0.5%). One eye which had CTR implantation without retractors required scleral suture fixation 4.4 years later.


From our study, the rate of CTR use was 0.84%. CTR implantation contributes to the prevention of zonular damage. Implantation of CTR with retractors may be better in maintaining zonular stability during cataract surgery.
