Partial-thickness scleral tethering suture for optimum fixation and centration of transscleral-sutured intraocular
1Western University, London, Ontario, Canada.
Abstract:
We describe a surgical technique for fine-tuning the centration of a transscleral-sutured modified capsular tension ring (CTR)-intraocular lens-capsular bag complex using a partial-thickness scleral tethering suture placed posterior to the external episcleral portion of a transscleral suture loop. The technique can be used for adjusting the centration of any intraocular supporting or prosthetic device that is transsclerally sutured in a "hanging" technique, such as capsular tension segments, modified CTRs, capsular anchoring devices, or iris prostheses.
