Explantation of Cloudy Oculentis Intraocular Lens With Primary Pars Plana Vitrectomy and Deflooring of the Capsular Bag.

BACKGROUND

To report a novel technique for explantation of cloudy Oculentis intraocular lens (IOL).

METHODS

A retrospective review of patient's electronic records was performed. The technique includes pars plana vitrectomy, deflooring (large posterior capsulectomy) of the capsular bag, IOL explantation with preserving the anterior capsule, and a secondary IOL placement.

RESULTS

Twenty eyes of 19 symptomatic patients were studied. Preoperative Snellen visual acuity ranged from 6/60 to 6/6; 15 eyes (75%) had visual acuity of 6/12 or better. Postoperative visual acuity ranged from 6/60 to 6/6; 18 eyes (90%) had visual acuity of 6/12 or better, and 2 eyes (10%) had visual acuity worse than 6/12. Among these eyes, 13 eyes (65%) had sulcus-fixated IOL, 5 eyes (25%) had sutureless scleral-fixated IOL, and 2 eyes (10%) had retropupillary iris clip IOL. Perioperative surgical complications included localized choroidal detachment in one eye and retinal detachment in another eye. In addition, most patients reported significant improvement in their postoperative vision satisfaction.

CONCLUSION

Our new technique for explantation of cloudy Oculentis IOL provides a standard surgery allowing a safe predictable and repeatable removal of these lenses comparing with the anterior segment approach. This technique could also be used for removal of other IOLs.
