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

PURPOSE: To describe a technique for the replacement of dislocation of plate-haptic trifocal intraocular lens (IOL) through double-suture 4-point flange intrascleral fixation.

DESIGN

Retrospective, interventional, noncomparative, case series.

METHODS

A total of 7 eyes of 7 patients with a dislocated plate-haptic trifocal IOL were enrolled for 4-point flange intrascleral fixation with double 7-0 polypropylene suture. Preoperative and postoperative visual acuity, operating time, refractive results, postoperative IOL tilt and decentration, and intraoperative and postoperative complications were recorded.

RESULTS

The mean postoperative uncorrected distance visual acuity (UDVA) was 0.05 ± 0.06 logarithm of the minimum angle of resolution (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 diopters. The visual function index-14 questionnaire showed that no difficulty was found in >80% of subjects for all tasks. The mean surgical time was 16.23 ± 5.64 min. 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.

CONCLUSION

We have described the technique of 4-point flange intrascleral fixation for plate-haptic trifocal IOL.
