Buonsanti Dual Hook is a system with a combination of both, an iris retractor and a capsule hook. It is used for simultaneously providing a temporary support to the capsular bag and for temporary retraction of the iris, without making too many incisions.
Capsular Tension Ring allow expansion and stabilization of the capsular bag to facilitate a safe IOL implantation and maintain good IOL centration. Capsular tension ring is a highly flexible clear PMMA ring of haptic thickness 0.18mm.
This is a modified CTR which has an additional fixation eyelet that allows it to be sutured to the scleral wall without piercing the capsular bag. This ring is used in cases where a standard CTR may not provide adequate centration and stability.
Canabrava Gupta Segment (Capsule Support Segment) is a partial ring of clear PMMA covering approximately one quadrant with a specially designed scleral fixation arm for permanent fixation.
