Purpose:
To describe a new technique for transconjunctival intrascleral fixation of Cionni CTR using double-flanged polypropylens suture.
Methods:
This is a prospective interventional case series which included 7 cases with severe (more than 180 degrees) zonular dialysis. Three cases were hereditary lens subluxation (Marfan syndrome), 2 cases with traumatic subluxation and 2 cases with pseudo-exfoliation syndrome.
Results:
All cases achieved a good postoperative stable and centered IOL with good visual results. No postoperative complications were recorded apart from PCO in 3 cases and mild bleeding during needle passage in one case.
Conclusion:
This described technique is a simple, time sparing and minimally invasive method for achieving good bag centration. It eliminates the need of conjunctival peritomy, subconjunctival vessels cautery and scleral fashioning of a flap, pocket or a groove. The use of 6/0 polypropylene theoretically can achieve better longevity.
