Abstract	PurposeTo compare the clinical outcomes of intrascleral fixation of the three-piece intraocular lenses (IOLs) 2.5 mm posterior to the limbus with ciliary sulcus implantation and transscleral fixation 2.5 mm posterior to the limbus.MethodsSixty-five eyes of 65 patients who underwent ciliary sulcus implantation or transscleral or intrascleral fixation of the AMO Sensar AR40e IOL were retrospectively reviewed. The postoperative refractive prediction error, back-calculated effective lens position (ELP), corrected distance visual acuity (CDVA), and postoperative residual cylinder were compared.ResultsThere were significant differences in the median (interquartile range) postoperative refractive prediction error (diopters [D]) among the three groups (p < 0.001): for ciliary sulcus implantation (33 eyes), −0.89 D (−1.21 to −0.56 D); for transscleral fixation (10 eyes), −0.40 D (−0.78 to −0.22 D); and for intrascleral fixation (22 eyes), 0.01 D (−0.28 to 0.34 D). Significant differences (p < 0.001) were observed in the median back-calculated ELP: for ciliary sulcus implantation, 4.35 mm (3.95 to 4.55 mm); for transscleral fixation, 4.51 mm (4.34 to 4.76 mm); and for intrascleral fixation, 4.90 mm (4.56 to 5.35 mm). There were no differences in the median postoperative CDVA (0, 0.10, and 0 logarithm of the minimum angle of resolution, respectively; p = 0.083) and the residual cylinder (−0.75, −1.50, and −0.63 D, respectively; p = 0.074) among three groups.ConclusionsIntrascleral fixation showed no myopic shift and the most posterior lens position, while ciliary sulcus implantation induced the greatest myopic shift and the most anterior lens position. However, there was no significant difference in the postoperative CDVA or astigmatism among the eyes with different IOL insertion methods, demonstrating good IOL stability and vision outcomes.
