Purpose: To evaluate the predisposing factors, management and visual prognosis of intraocular Lens (IOL) dislocation into the posterior segment.

Methods: The cases of posterior IOL dislocation from January 2012 to May 2017 at 2 centers were reviewed. Only eyes with dislocations requiring IOL explantation or repositioning were included. Predisposing factors, interval between cataract surgery and IOL dislocation, circumstances of onset, management, and postoperative complications are reported.

Results: 72 eyes of 72 patients were included. The mean age was 67.6 years. 47 patients (68%) were men. The mean time interval from cataract surgery to IOL dislocation was significantly shorter in the out-of-the bag group than the in-the-bag IOL dislocation group (3.8 months vs 132 months, P=0.002). Predisposing factors for out-of-the-bag IOL dislocation were mainly capsular rupture and/or zonular dehiscence (83%) after complicated cataract surgery. The predisposing factors for in-the-bag IOL dislocation were high myopia (40%), pseudoexfoliation syndrome (40%), previous vitrectomy (38%), or Marfan syndrome (3%) with uneventful cataract surgery. The type of luxated implant was mainly a 3-piece foldable IOL (50%), followed by foldable one-piece IOL (28%) and a rigid one-piece IOL (17%). Most cases of posterior chamber IOL dislocation occurred spontaneously (80%) without a trigger event. Management consisted of a posterior approach in 24 cases (33%) or an anterior approach in 48 cases (67%), associated with IOL repositioning in 20 eyes (28%), and IOL replacement in 34 eyes (47%). Finally, 18 eyes (25%) were left aphakic. Postoperative complications occurred in 7 cases (9.7%).

Conclusions: Predisposing factors and time from cataract surgery to IOL dislocation were different for out-of-the bag versus in-the-bag IOL dislocation. Management of IOL dislocation varied considerably, depending on surgeon preference and experience. Surgery for IOL dislocation significantly improved best corrected visual acuity and was associated with a low complication rate.

Purpose: Anterior chamber air injection (ACAI) is a surgical technique used to decrease the occurrence of postoperative intraocular lens (IOL) haptic dislocation following phacovitrectomy with gas/air tamponade. The impact of this technique on IOL stability remains uncertain, prompting the design of this study to investigate further.

Methods: This study included 51 eyes of 51 patients who underwent phacovitrectomy with gas/air tamponade.

Article Synopsis
  • The study evaluated the long-term outcomes of scleral fixation of aniridic black diaphragm intraocular lenses (BDIOL) in 38 eyes affected by aniridia and aphakia due to trauma or congenital conditions.
  • After an average follow-up of 28 months, there was a significant improvement in visual acuity, and patients reported reduced glare and photophobia, though some experienced complications like elevated intraocular pressure and corneal decompensation.
  • The findings suggest that scleral fixation of BDIOL is an effective solution for patients lacking capsular support, providing good vision quality with a low rate of complications, regardless of prior surgical history.

Comparing dislocation force between a flanged haptics IOL and a harpoon haptics IOL.

Sci Rep

December 2024

Vienna Institute for Research in Ocular Surgery (VIROS), A Karl Landsteiner Institute, Hanusch Hospital, Vienna, Austria.

To compare two different secondary IOL fixation techniques, either flanged or hooked, regarding the least required force to dislocate the haptic in human corneoscleral donor tissue (CST). Experimental laboratory investigation. The least required dislocation force (LRDF) of two different fixation techniques, namely the flanged haptics (FH, as described by Yamane) and the harpoon haptic technique (HH, as described by Carlevale) were investigated using 20 three-piece IOLs (KOWA PU6AS) and 20 single-piece IOLs (SOLEKO CARLEVALE) fixated to human scleral tissue.

Closed globe refixation of the IOL-bag complex with the ab-externo 8-exit-4-point fixation technique.

Indian J Ophthalmol

Department of Vitreo-Retina, Narayana Nethralaya, Bengaluru, Karnataka, India.

Intraocular lens (IOL) dislocation is not an uncommon complication and often requires surgical intervention, depending on the status of capsular bag support. Conventionally, posterior dislocation of a foldable IOL or the IOL-bag complex warrants their removal as foldable IOLs are not ideal for sulcus placement. The technique presented here describes using quadrilateral sutures to refix looped haptic IOLs at the ciliary sulcus with or without a bag complex.

Retropupillary Iris Clip Intraocular Lenses: A Case Series of 57 Eyes.

January 2025

Westmead and Central Clinical Schools, Specialty of Ophthalmology and Eye Health, The University of Sydney, Sydney, NSW, Australia.

Purpose: To report visual and refractive outcomes and intraoperative and postoperative complications after pars plana vitrectomy (PPV) with retropupillary implantation of an iris clip intraocular lens (IOL).

Methods: This is a retrospective case series of patients who underwent secondary retropupillary intraocular lens insertion combined with pars plana vitrectomy to treat aphakia secondary to a dislocated nucleus lens (group A); or IOL dislocation (group B). Patient demographics, preoperative visual and refractive outcomes, intraoperative factors, postoperative visual and refractive outcomes, and complications within the follow-up period ranging from 6 months up to 3 years postoperative, were recorded.
