Scleral Loop Fixation for Posteriorly Dislocated Intraocular Lenses

Modified transscleral fixation technique for refixation of dislocated intraocular lenses

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Repositioning the IOL is theoretically the best surgical option because in most cases it is less traumatic than explanting the IOL and may provide optimum long-term visual and structural stability. 12 The IOL can be repositioned in the ciliary sulcus, especially when adequate peripheral capsule support remains.…”

“…1,2 There are many techniques of transscleral suture fixation of dislocated IOLs. [1][2][3][4][5][6][7][8][9][10][11][12] They are generally divided into 2 main categories. The first, extraction of the dislocated IOL with an open-system method, carries the risk for vitreous prolapse, collapse of the ocular structures, intraocular bleeding, and significant surgically induced astigmatism.…”

“…13 Previously reported closedeye techniques, however, have disadvantages including technical difficulty, an increased risk for damage to intraocular components, multiple instrument passage from incisions, and insecure suture knots. [4][5][6][7][8][9] We evaluated the long-term outcomes in a series of patients in whom a modified technique of temporary externalization of the haptics was used to refixate dislocated PC IOLs. Conditions for exclusion included active proliferative diabetic retinopathy and retinal detachment.…”

Ab externo direct suture technique for dislocated intraocular lens

“…The first includes techniques in which a suture loop is created around the haptic by surgical maneuvers around the dislocated PC IOL inside the eye. [10][11][12][13][14][15][16][17] Creating a loop around the haptic by intraocular maneuvers may require multiple sclerotomy sites, multiple instrument passes, and specially designed instruments. Moreover, there is a potential risk for IOL redislocation caused by the haptic slipping from the suture loop with internal looping techniques.…”

Pars plana vitrectomy with transscleral fixation of posterior chamber lens in the treatment of post-traumatic lens dislocation

“…If no sufficient support from the lens capsules is provided, the IOL can be implanted in the anterior chamber, fixated to the iris (the iris claw type) or implanted in the posterior chamber and fixed with scleral sutures [5][6][7][8][9][10][11][12][13].…”
