Abstract

Objective Intraocular lens (IOL) repositioning using a closed-eye approach could be carried out in some selected cases. Our study focuses on the efficacy and safety of a IOL closed-eye repositioning technique using scleral suture, which is performed using a trocar as an intrastromal limbal guide.

Methods and analysis Thirty-one eyes of 31 patients with late IOL dislocation operated on between January 2015 and May 2017 were included in this retrospective non-comparative consecutive case series study. The patients had a single-piece in-the-bag dislocation or a 3-pieces in-the-bag or out-of-the-bag dislocation. The patients underwent an anterior vitrectomy and a scleral refixation in a closed chamber using a 10/0 polypropylene suture passed through a 25 Gauge trocar inserted in the anterior chamber.

Results The mean follow-up time was 19.54 months. Average preoperative best-corrected visual acuity (BCVA) was 0.73 LogMar (±0.21 SD); while average postoperative BCVA was 0.27 LogMar (±0.23 SD). Fifteen patients underwent anterior pars plana vitrectomy (PPV) while 16 patients did not; moreover, two patients underwent PPV. Six patients had an increase of postoperative intraocular pressure, two patients had postoperative decentration, two patients had postoperative cystoid macular oedema, none of the patients had major complications such as retinal detachment, choroidal detachment, malignant glaucoma, irreversible corneal decompensation and endophthalmitis.

Conclusion We can affirm that our technique may be safe and useful in the case of 3-piece in-the bag or out-of the bag dislocated IOLs and also in the case of in-the-bag single-piece dislocated IOLs.
