Abstract

Background: To present the follow-up outcomes of a modified technique of transscleral suture fixation of posterior chamber intraocular lens (PCIOL) in eyes with inadequate capsule support.

Methods: A retrospective chart review of 21 patients underwent transscleral suture fixation of a foldable 3-looped haptics one-piece PCIOL implantation through scleral pockets was conducted. Preoperative data and follow-up data for at least 3 months were collected for all patients.

Results: The mean operative duration was 36.62 ± 10.70 min. The mean pre- and post-operative LogMAR uncorrected distance visual acuity was (1.25 ± 0.50 vs. 0.41 ± 0.22, P < 0.01). The mean pre- and post-operative LogMAR best corrected visual acuity was (0.48 ± 0.25 vs. 0.33 ± 0.24, P < 0.01). The mean proportion of postoperative endothelial cell loss was 11.46 ± 4.78%. The mean postoperative anterior chamber depth was 3.05 ± 0.44 mm. The mean postoperative IOL tilt degree was 2.81 ± 1.41°, and the mean postoperative IOL decentration degree was 0.31 ± 0.13 mm. Four patients with transient corneal edema (19.0%) and three patients with transiently elevated IOP (14.3%) were observed after operation, and such complications were resolved within 1 week. No severe complications were observed.

Conclusions: The modified technique was a feasible method of PCIOL implantation.

Schematic procedures of modified technique for PCIOL fixation. a Three 3-mm wide limbus-parallel half-thickness corneal incisions were made at the limbus. b Three 3 × 2 mm scleral pockets were dissected. A 3.5-mm wide superior corneal incision was made. c A double-armed suture was tied to one haptic of the PCIOL, and one of its needle suture was passed through the superior corneal incision and guided out of the eye from scleral pockets by a docking hollow needle. d The other needle suture was passed through the superior corneal incision and guided out at an adjacent position in the same way. e Sutures were tied on every haptic of the PCIOL and guided out of the eye from their corresponding scleral pocket beds. f The PCIOL position was set by adjusting tension of each suture knot
