Potential Risk in Combined Use of Capsule Retractors and Capsular Tension Rings

Burak Ulas and Altan Atakan Ozcan

The aim of this study, present a complication associated with capsular tension ring (CTR) implantation after placement of capsule retractors.

A 66-year-old man presented with progressive bilateral vision loss. He had no history of ocular trauma, and previous eye surgery. In ophthalmological examination bilateral large zonular deficiency had been noted in both eyes. The remaining ocular and medical history was unremarkable. Cataract extraction with IOL placement was performed in the right eye by the help of capsule retractors and CTR.

On attempted removal one of the capsule retractor, it was discovered that the CTR had passed through the retractor's distal loop. Additional gently manipulation and rotation of the CTR through the retractor’s distal loop was ended with atraumatic removal of the capsule retractor.

Though capsule retractors improve challenge of weak zonules during cataract surgery, the instrument itself may cause complications and unwanted problems when combined use with CTRs.
