Abstract
- Background: To compare the clinical features and long‐term treatment outcomes of patients undergoing secondary intraocular lens (IOL) surgery with scleral‐fixated (SFIOL) versus retropupillary iris‐claw IOL (RPICIOL). Methods: Consecutive patients treated between June 2014 and December 2019 at two tertiary centres were retrospectively reviewed. The primary outcome was the best‐corrected visual acuity (BCVA). Secondary outcomes included factors associated with significant corneal endothelial injury and postoperative redislocation. Results: This study included 395 eyes undergoing surgery with SFIOL (237 eyes, 60%) or RPICIOL (158 eyes, 40%), with no differences in baseline BCVA (p = 0.76) or endothelial cell density (ECD) (p = 0.39). Compared with the SFIOL group, the RPICIOL group had faster visual recovery (postoperative month 1, 20/37 vs. 20/46, p = 0.005) sustained to over 36 months (p = 0.034), favourable absolute prediction errors (within 0.5D, 67.3% vs. 54.9%, p = 0.027), and shorter operation times (52.7 vs. 60.9 min, p = 0.015). There was no difference in ECD after 12 months (P = 0.282). Over a mean follow‐up duration of 33 months (152 cases >3 years, 38.5%), the SFIOL group experienced more cases of tilted/decentred IOLs (14 vs. 1, p = 0.006), suture exposure (7 vs. 0, p = 0.045), and redislocation (17.7% vs. 10.1%, p < 0.001). Multivariable regression showed that a final BCVA below 20/40 was associated with SFIOL (P = 0.007), older age (p = 0.001), intraoperative complications (p = 0.002), past history of vitrectomy/glaucoma surgery or uveitis (p = 0.046), and surgically induced astigmatism >1D (p = 0.029). Conclusions: RPICIOL appears to be a safe and effective surgical option for secondary IOL surgery over a long‐term follow‐up, comparing favourably against conventional SFIOL. [ABSTRACT FROM AUTHOR]
