Abstract Details


To evaluate the 1-year stability of a one-piece hydrophobic acrylic aspheric intraocular lens (IOL) with haptics anteriorly offset.


Miyata Eye Hospital


The prospective comparative case series comprised 28 eyes of 18 patients who were implanted with the one-piece hydrophobic acrylic aspheric IOL with haptics anteriorly offset, and 32 eyes of 32 patients implanted with a three-piece IOL with the same optic platform and material, except for angled open-loop haptics. The best-corrected distance visual acuity, refractive prediction error, IOL decentration and tilt, and anterior chamber depth (ACD) during the 12-month follow-up period were compared.


There was no difference in the postoperative visual function between the two IOL groups. The one-piece IOL was associated with significant refractive prediction errors toward hyperopia (P<0.001), smaller decentrations (P<0.006), and deeper ACDs (P<0.004), while the IOL tilt did not differ.


The one-piece IOL was stable in the capsular bag during the 1-year follow-up period with less decentration. The refractive prediction error and ACD in the one-piece IOL demonstrated closer contact between the IOL anterior and the posterior capsule.
