Abstract Details

Purpose:

To analyze internal High-order aberrations (HOAs) in pseudophakic eyes that received asymmetric refractive multifocal intraocular lens (IOL) implantation and to investigate the relationships between biometric data and the effectiveness of multifocal IOL implantation.

Setting:

Yeouido St.Mary hospital, Seoul, Republic of Korea Keye Hospital, Seoul, Republic of Korea

Methods:

This retrospective study included 90 eyes of 90 patients who underwent implantation of asymmetric rotationally refractive multifocal IOL (Lentis Mplus LS-312MF ). The SS-OCT (Argos, Movu, Inc.) was used for measurements of preoperative biometry (axial length, anterior chamber depth, lens thickness, and central corneal power). Internal HOAs were measured 3 months postoperatively using the OPD scan III (Nidek) at a pupil diameter of 5.0 mm. We investigated the relationships between biometric data and postoperative internal HOAs.

Results:

Mean RMS of internal coma and trefoil were 0.33 ± 0.11µm and 0.55 ± 0.14µm. Postoperative internal coma aberration showed statistical correlations with preoperative axial length and anterior chamber depth. (r = -0.23, p < 0.001 / r = -0.19, p = 0.04). Postoperative internal trefoil aberration also changed according to preoperative axial length and anterior chamber depth. (r = -0.33, p < 0.001 / r = -020., p = 0.03)

Conclusions:

Postoperative internal coma and trefoil were influenced by preoperative axial length and anterior chamber depth after the asymmetric rotationally refractive multifocal IOL implantation. Preoperative biometric measurements should be considered to optimize presbyopic correction with asymmetric refractive multifocal IOL.
