In the bag IOL dislocation following uncomplicated phacoemulsification

Spontaneous Late Intraocular Lens and Capsule Tension Ring Dislocation

“…4 The incidence of repositioning or exchange procedures for dislocated IOL ranges between 0.2% and 3%. 5,13 Mönestam 5 reported that 0.6% of patients were at risk of required surgery for a dislocated IOL 10 years after initial surgery.…”

“…11,14,15 Fibrotic contraction and opacification of the anterior capsule usually occurs 3 to 6 months after surgery, but spontaneous dislocation of the IOL with CCS and extensive constriction of the capsular bag following uncomplicated surgery may occur many months to several years later. 4,6 Kumar et al 4 reported two cases aged 83 and 74 years with IOL dislocation within the bag 3 and 6 months after surgery, respectively. To correct visual deterioration they had removed dislocated IOLs from the bag and implanted rigid IOLs in the sulcus for each patient.…”

“…1,2 These changes could lead to intraocular lens (IOL) decentration within the capsular bag followed by dislocation or total IOL luxation into the vitreous cavity. 3,4,5 Early IOL dislocation occurs in cataract surgery with inadequate support for the IOL resulting from intraoperative zonular or capsular damage, but late dislocation following uncomplicated surgery usually occurs several months to many years postoperatively. 4,5,6,7,8 …”

“…2,9,10,11,12 Surgical factors including capsulorhexis size and IOL design and materials may also influence the development of CCS and IOL dislocation. 4,5,12 …”

Sutured Sulcus Fixation of an Anteriorly Dislocated Endocapsular Intraocular Lens

“…Similar factors may be implicated in endocapsular IOL dislocations in patients with pseudoexfoliation syndrome. 24 We describe an accurate and rapid method for fixating the IOL to the ciliary sulcus via a small-incision anterior segment approach, avoiding the potential difficulties associated with lens replacement.
