Four-Point Flange Intrascleral Fixation With Double Suture Through the Dislocated Plate-Haptic Trifocal Intraocular Lens

Abstract

To describe a technique for the replacement of dislocation of plate-haptic trifocal intraocular lens (IOL) through double-suture four-point flange intrascleral fixation. Retrospective, interventional, noncomparative, case series METHODS: A total of 7 eyes of 7 patients with a dislocated plate-haptic trifocal IOL were enrolled for four-point flange intrascleral fixation with double 7-0 polypropylene suture. Preoperative and postoperative visual acuity, operating time, refractive results, postoperative IOL tilt and decentration, intra-operative and postoperative complications were recorded. The mean postoperative uncorrected distance visual acuity (UDVA) was 0.05 ± 0.06 logMAR. The mean postoperative uncorrected intermediate visual acuity (UIVA) at 80 cm was 0.09 ± 0.06 logMAR and the mean postoperative uncorrected near visual acuity (UNVA) at 40 cm was 0.06 ± 0.07 logMAR. The mean postoperative residual spherical equivalent values were - 0.27 ± 0.39 D. VF-14 questionnaire showed that no difficulty was found in >80% of subjects for all of the tasks. The mean surgical time was 16.23 ± 5.64 minutes. The mean tilt of IOL was 3.74 ± 1.31° and the mean decentration of the IOL was 0.18 ± 0.09 mm. No important complications appeared. The authors have described the technique of four-point flange intrascleral fixation for plate-haptic trifocal IOL.
