Purpose: To compare the efficacy and safety of conventional scleral fixation (C-SF), retropupillary iris-claw intraocular lens(RP-IOL) implantation, and intrascleral fixation (ISF). Methods: This retrospective observational study included 58 patients (58 eyes) who underwent C-SF (23 eyes), RP-IOL (23eyes), and ISF (12 eyes) by a single surgeon at Samsung Medical Center from October 2017 to July 2020 and were followed upfor at least 6 months. This study analyzed various clinical outcomes before surgery, and 1 day, 1 week, 1 month, 3 months,and 6 months after surgery. Results: Six months after surgery, best-corrected visual acuity in logarithm of minimum angle of resolution was 0.08 ± 0.10,0.08 ± 0.16, and 0.03 ± 0.04 in C-SF group, RP-IOL group, and ISF group, respectively, and there was a significant improvementin each group compared to preoperative best-corrected visual acuity. All groups showed a significant increase in astigmatismpostoperatively, but no between-group differences were observed. The prediction error was -0.15 ± 0.77, 0.56 ± 0.62, and 0.44± 1.00 diopters in the three groups, respectively, indicating RP-IOL group and ISF group for hyperopic shift. The three groupsdid not differ in terms of absolute prediction error. Six months after surgery, the corneal endothelial cell counts were 2,073 ±691, 2,014 ± 692, and 1,712 ± 891 cells/mm2, respectively, which were lower than before surgery. IOL dislocation occurred infive eyes only in RP-IOL group, two of which underwent two reoperations, and reenclavation was performed smoothly withoutcomplications in all cases. Conclusions: Although the frequency of IOL dislocation in RP-IOL group was higher than that in the other groups, it can bereenclavated relatively easily. As a method of secondary IOL fixation, both RP-IOL implantation and ISF were as effective asconventional scleral fixation.
