[Evaluation of the modified capsular tension ring in cases of traumatic lens subluxation].
OBJECTIVE
To evaluate the behavior of the modified capsular tension ring (MCTR) in traumatic subluxated cataracts analyzing the visual acuity, centration of the capsular bag, pseudophacodonesis, postoperative follow-up and intra- and postoperative complications.


METHODS
Cincinnati Eye Institute, Cincinnati, Ohio, USA.


METHODS
Twenty-two eyes of 22 patients with traumatic loss of zonular support had phacoemulsification using PCIOL and MCTR implantation. The preoperative examination included best correct visual acuity (BCVA) and the presence or absence of phacodonesis, lens decentration and vitreous prolapse. The postoperative evaluation included BCVA, the presence of pseudophacodonesis, PCIOL centration, necessity of vitrectomy and other complications.


RESULTS
21 eyes (95.45%) had an improvement in BCVA. The preoperative examination disclosed phacodonesis in 11 eyes (50%) and no eye presented pseudophacodonesis in the postoperative period. Preoperatively, symptomatic decentration was presented by 10 eyes (45.45%) and 22 eyes (100%) had no decentration after surgery. The preoperative examination revealed vitreous prolapse in the anterior chamber in 9 eyes (40.90%). Vitrectomy was required in 11 eyes (50%).


CONCLUSIONS
The use of the MCTR resulted in a good centration of the capsular bag and the PC IOL in 22 eyes with traumatic cataract and loss of zonular support.
