Purpose Of Review:
To discuss current designs, indications, contraindications and controversies pertaining to capsular tension devices.
Recent Findings:
Capsular tension rings and other newer endocapsular support devices have become increasingly important in the management of zonular weakness during cataract extraction. They have been found to improve both intraoperative support during phacoemulsification and postoperative intraocular lens centration. Since the introduction of the original capsular tension rings in 1991, there has been a progressive evolution of this device to help deal with profound zonular weakness. These newer devices, which permit scleral-suture fixation, include the modified capsular tension ring and the capsular tension segment.
Summary:
Continual advances in capsular tension device technology have allowed for increased safety and efficacy in performing cataract surgery in patients with zonular weakness with newer devices being evolved to manage more profound cases.
