摘　　要：Background:To investigate the decentration and tilt of plate-haptic multifocal intraocular lenses(MfIOLs)in myopic eyes.Methods:Myopic(axial length[AXL]>24.5 mm)and non-myopic(21.0 mm<AXL≤24.5 mm)cataract eyes were enrolled in this prospective study and randomly assigned to receive implantation of Zeiss AT LISA tri 839MP lenses(Group A)or Tecnis ZMB00 lenses(Group B).In total,122 eyes of 122 patients were available for analysis.Decentration and tilt of MfIOLs,high-order aberrations(HOAs),and modulation transfer functions(MTFs)were evaluated using the OPD-Scan III aberrometer 3 months postoperatively.Subjective symptoms were assessed with a Quality of Vision questionnaire.Results:Near and distance visual acuities,tilt and horizontal decentration did not differ between the two groups,postoperatively.However,myopic eyes of Group B showed greater vertical decentration than those of Group A(−0.17±0.14 mm vs.-0.03±0.09 mm,respectively),particularly when the MfIOLs were placed horizontally or obliquely.Overall decentration of myopic eyes was greater in Group B than in Group A(0.41±0.15 mm vs.0.16±0.10 mm,respectively).In Group B,AXL was negatively correlated with vertical decentration and positively correlated with overall decentration.No such correlations were found in Group A.Intraocular total HOAs,coma,trefoil and spherical aberrations were lower in Group A than in Group B for a 6.0 mm pupil among myopic eyes.Generally,Group A had better MTFs and fewer subjective symptoms than Group B among myopic eyes.Conclusions:Plate-haptic design of MfIOLs may be a suggested option for myopic cataract eyes due to the less inferior decentration and better visual quality postoperatively.
