BackgroundTo evaluate rotation and its influencing factors of an aspheric one-piece hydrophobic acrylic intraocular lens (IOL) Vivinex XY1 during 6 months after operation.MethodsIn this institutional trial, 122 eyes of 66 patients were implanted with a non-toric aspheric IOL Vivinex XY1 (Hoya Corporation, Tokyo, Japan). IOL alignment was assessed at the end of surgery, 1 hour, 1 week, 1 month and 6 months after implantation. Confounding factors such as axial length, presence of anterior fibrosis and randomised implantation in four different intended axes (0°, 45°, 90°, 135°) were evaluated. Decentration and tilt were measured using a Purkinje metre.ResultsAssessment of rotational stability was possible for 103 of 122 implanted IOLs 6 months after eye surgery. The median absolute rotation was 1.1° (range: 0°–5°). Rotation was significantly increased within the first hour after operation compared with later time-points (p<0.001). No correlation was found with axial length and rotation (Spearman’s r=0.048, p=0.63). No significant difference was observed regarding different implantation axes (p=0.75). Rotation was not influenced by the presence of anterior fibrosis (p=0.98).ConclusionAssessing the true IOL position at the end of surgery is crucial for the evaluation of rotational stability of IOLs. No IOL rotation exceeding 5° could be detected 6 months after surgery.

A 59 years old man presented with a history of phacoemulsification with an hydrophobic intraocular lens implant in his left eye 4 years ago. The biomicroscopy revealed pigments in the corneal endothelium (Krukenberg’s spindle), peripheral transillumination of the iris and intraocular pressure of 52 mmHg in the left eye. Gonioscopy revealed hyperpigmentation of the posterior trabeculate. Posterior segment examination and visual field revealed a cup/disc 0.9 with significant field damage in strategy 10-2. Biomicroscopic ultrasonography showed asymmetric implantation of the IOL loops in the left eye (one loop in the ciliary sulcus and the other in the capsular bag). He underwent antiglaucomatous treatment with adequate control of intraocular pressure, with no need for surgical intervention.

ObjectiveIntraocular 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 analysisThirty-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.ResultsThe 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.ConclusionWe 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.
