متن کاملManagement of posteriorly dislocated capsular tension ring with vitrectomy using a “chandelier” illumination system
Subluxation of the capsular tension ring (CTR) into the vitreous is a rare complication. The explantation of these rings from the vitreous by conventional vitrectomy is often a difficult procedure requiring great surgical skill. We report two cases of posteriorly subluxated endocapsular rings, which were explanted with pars plana vitrectomy using the chandelier illumination system. This illumin...
متن کاملCapsular Tension Rings
Cataract surgery in an eye with absent or weak zonules presents unique challenges for the anterior segment surgeon. With the introduction of the capsular tension ring (CTR), and its several modified versions, the ability to perform safe cataract extraction with the implantation of a stable and well-centered intraocular lens (IOL) within the capsular bag has increased substantially. In order to ...
متن کاملOptimal Implantation Time for a Capsular Tension Ring
P erforming cataract extraction in patients with zonular weakness presents many challenges and increases the risk of intraand postoperative complications. Capsular tension rings (CTRs) and other endocapsular support devices have been important management options for patients with significant zonulopathy. Hara et al1 and Nagamato and Bissen-Miyajima2 introduced the first endocapsular devices, bu...
متن کاملThe effect of capsular tension ring on posterior capsular opacity in cataract surgery.
This study was performed to evaluate the efficacy and safety of the capsular tension ring on posterior capsular opacity in comparison with cases undergoing intraocular lens (IOL) implantation alone. We analyzed 127 eyes which had undergone cataract surgery, including capsular tension ring insertion, along with 127 eyes which had undergone IOL implantation alone by the same surgeon from Septembe...
