PURPOSE: To evaluate the outcomes of implantation of a Cionni modified capsular tension ring (CTR) and a posterior chamber intraocular lens (PC IOL) in patients with traumatic cataract and loss of zonular support.
SETTING: Eye Clinic II, Haydarpasa Numune Education and Research Hospital, Istanbul, Turkey.
DESIGN: Case series.
METHODS: Eyes with traumatic cataract and loss of zonular support had phacoemulsification with implantation of a foldable IOL and a 1- or 2-eyelet modified CTR. Preoperative features, preoperative and postoperative corrected distance visual acuity (CDVA), intraoperative performance, IOL position, and complications were evaluated.
RESULTS: The study enrolled 16 eyes (16 patients). The mean CDVA was 0.89 logMAR ± 0.41 (SD) preoperatively and 0.33 ± 0.43 logMAR at the last postoperative examination (P=.001). Postoperatively, the mean spherical equivalent was -0.23 diopter (D) (range -1.50 to +1.00 D) and the mean postoperative astigmatism, 1.59 D (range 0.50 to 4.00 D). Eight eyes (50.0%) had phacodonesis preoperatively; no eye had pseudophacodonesis postoperatively. Preoperatively, 10 eyes (62.5%) had symptomatic decentration. Two eyes (12.5%) had asymptomatic nonprogressive decentration in the early postoperative period; no eye had symptomatic decentration throughout the follow-up. Three eyes (18.8%) preoperatively and 1 eye (6.2%) postoperatively had vitreous in the anterior chamber. Four eyes (25.0%) required anterior vitrectomy. Other complications were symptomatic posterior capsule opacification in 8 eyes (50.0%) and transient increased intraocular pressure in 2 eyes (12.5%).
CONCLUSION: The use of a modified CTR preserved the capsular bag and resulted in good PC IOL centration with few significant complications in patients with traumatic cataract and loss of zonular support.
