摘要
目的比较两种散光矫正型人工晶状体(TIOL)植入术后早期旋转度、偏心值及视觉质量。方法2022年6月至2023年1月在乐山市眼科中心接受超声乳化白内障摘除联合TIOL植入术的老年性白内障患者,所有患者按眼轴长度分为近视组及非近视组,按植入人工晶状体(IOL)类型再分为SN6AT组和709M组。比较术后1天、1周和1月各组IOL旋转度、裸眼远视力、等效球镜度、IOL偏心值、客观视觉质量。结果术后1天、1周时,近视组较非近视组IOL旋转度增大(P<0.05),而在术后1月时,近视组中709M组相较于SN6AT组IOL旋转度更小(P<0.05)。术后1天、1周和1月时,近视组的IOL偏心值均大于非近视组;且术后1月时,无论近视组或非近视组,709M组的IOL偏心值均小于SN6AT组。术后1天、1周和1月时,非近视组中SN6AT组与709M组的PSF、SR、MTF、HOA比较,差异均无统计学意义(P>0.05),而近视组中709M组较SN6AT组的PSF更小、SR更大、MTF更大、HOA更小(P<0.05)。结论在近视患者中,相比于C形襻的TIOL,板状襻TIOL具有更佳的术后稳定性(旋转度及偏心值)和视觉质量。
Objective To compare early intraocular lens(IOL)rotation degree,decentration,and visual quality between two types of astigmatism-correcting intraocular lenses after surgery.Methods Elderly cataract patients who underwent phacoemulsification with toric intraocular lense(TIOL)implantation at Leshan Eye Center in our hospital between June 2022 and January 2023 were select-ed.All patients were stratified into a myopic and a non-myopic group based on axial length.The patients were further categorized into a SN6AT group or a 709M group according to the implanted IOL type.The IOL rotation,naked eye distance visual acuity,spherical e-quivalent,IOL decentration and objective visual quality were compared among the groups after 1 day,1 week and 1 month of surgery.Results The IOL rotational degrees were greater in the myopic group compared to the non-myopic group after 1 day and 1 week of sur-gery(P<0.05).However,after 1 month of surgery,the IOL rotational degrees were smaller in the myopic 709M group compared to the SN6AT group.The IOL eccentricity values in the myopic group were higher than those in the non-myopic group after 1 day,1 week,and 1 month of surgery.Regardless of the myopic group or the non-myopic group,the IOL decentration value of the 709M group was smaller than that of the SN6AT group.There were no statistically significant differences in PSF,SR,MTF,and HOA between the non-myopic SN6AT group and the 709M group after 1 day,1 week,and 1 month of surgery(P>0.05).The myopic 709M group had smaller PSF,larger SR,larger MTF,and smaller HOA than the SN6AT group(P<0.05).Conclusions Among myopic patients,compared to C-loop TIOL,plate-loop TIOL exhibits better postoperative stability(rotation and eccentricity values)and visual quality.
