ABSTRACT
The objective of the study was to evaluate the curative effect of a modified technique of scleral suture fixation with a four-loop foldable intraocular lens (IOL) for eye with inadequate capsule support. This was a retrospective study of 22 eyes with inadequate capsule support of 20 patients who underwent the scleral suture fixation technique with 9-0 polypropylene suture and foldable four-loop IOL implant. Preoperative and follow-up data were collected for all patients. The mean follow-up was 5.08 ± 0.48 months (range: 3–12 months). The mean pre- and postoperative log of minimum angle of resolution (logMAR) uncorrected distance visual acuity was 1.11 ± 0.32 versus 0.09 ± 0.09 (P < 0.001). The mean pre- and postoperative logMAR best corrected visual acuity was 0.37 ± 0.19 versus 0.08 ± 0.07 (P < 0.001). The intraocular pressure (IOP) increased briefly (range: 21–30 mmHg) in eight eyes on the first day postoperatively and returned to normal within 1 week. No IOP drops were used postoperatively. The IOP was 12–19.3 (13.72 ± 1.28) in this follow-up, which had no significant difference compared to the preoperative IOP (t = 0.34, P = 0.74). At this follow-up, there was no hyperemia, local hyperplasia, obvious scar, suture knots, or segment ends observed under the conjunctiva, as well as no pupil deformation or vitreous hemorrhage. The mean postoperative IOL decentration degree was 0.22 ± 0.08 mm. At the 7-day follow-up postoperatively, one side of the IOL was dislocated to the vitreous cavity in one case, which was resolved by reimplantation of a new IOL in time with the same technique. Scleral suture fixation technique of a four-loop foldable IOL was a feasible operation method for an eye with inadequate capsular support.
