目的比较三焦点与单焦点人工晶状体(IOL)植入术后1年视觉质量。
方法采用队列研究设计,纳入2017年5月至2018年6月在南京大学医学院附属鼓楼医院行超声乳化白内障摘出联合IOL植入术的年龄相关性白内障患者41例41眼,根据患者意愿将其分为三焦点IOL组20例20眼和单焦点IOL组21例21眼,分别植入AT LISA tri 839MP三焦点IOL和603P单焦点IOL。术后随访1年,检测2个组患者术后1年裸眼远距离视力(UCDVA)、裸眼中距离视力(UCIVA)、裸眼近距离视力(UCNVA)、最佳矫正远视力(BCDVA)、远视力矫正下的中距离视力(DCIVA)和远视力矫正下的近距离视力(DCNVA);采用OQAS Ⅱ检测患者点扩散函数(PSF)、调制传递函数(MTF)截止频率、斯特尔比率(SR),以及对比度分别为100%、20%、9%时的OQAS Ⅱ值(OV 100%、OV 20%、OV 9%)及客观散射指数(OSI);采用iTrace视功能分析仪评估患者的波前像差,包括全眼总像差(TA)、总高阶像差(tHOAs)、球差、彗差、三叶草像差、总低阶像差(tLOAs)、离焦、散光,所有像差值用均方根表示;采用综合验光仪检测2个组患者术眼不同调节范围内的视力,并以高于0.5 LogMAR视力绘制离焦曲线图;采用裂隙灯显微镜观察并以Sellman法量化分析2个组患者IOL区域内后囊膜混浊(PCO)发生程度;采用视功能指数量表(VF-14)对视功能进行评分。
结果术后1年,三焦点IOL组患者UCIVA、UCNVA、DCIVA和DCNVA明显优于单焦点IOL组,差异均有统计学意义(均 P<0.001)。OQAS Ⅱ视觉质量指标显示,三焦点IOL组患者MTF截止频率、SR、OV 100%及OSI值明显高于单焦点IOL组,差异均有统计学意义(均 P<0.001)。2个组患者各波前像差比较,差异均无统计学意义(均 P>0.05)。离焦曲线显示,单焦点IOL组组患者在-1.0、-1.5、-2.0、-2.5、-3.0、-3.5 D时(即相当于1 m、66 cm、50 cm、40 cm、33 cm、29 cm)的LogMAR视力明显高于三焦点IOL组,差异均有统计学意义(均 P<0.05)。三焦点IOL组PCO例数多于单焦点IOL组,差异有统计学意义( χ 2 =41.0, P<0.001)。三焦点IOL组的VF-14评分为87.99±1.09,明显高于单焦点IOL组的81.49±1.67,差异有统计学意义( t=10.301, P<0.001)。
结论三焦点IOL植入术后1年患者全程视力及主观视觉质量、客观视觉质量均优于单焦点IOL。
ObjectiveTo compare the one-year postoperative visual quality after trifocal intraocular lens (IOL) implantation and monofocal IOL implantation.
MethodsA cohort study was conducted.Forty-one eyes from 41 age-related cataract patients who underwent phacoemulsification extraction combined with IOL implantation in Nanjing Drum Tower Hospital from May 2017 to June 2018 were enrolled.The patients were divided into trifocal IOL group (20 eyes) receiving ZEISS AT LISA tri 839MP trifocal IOL implantation and monofocal IOL group (21 eyes) receiving ZEISS 603P monofocal IOL implantation according to their willingness.One year after surgery, uncorrected distant visual acuity (UCDVA), uncorrected intermediate visual acuity (UCIVA), uncorrected near visual acuity (UCNVA), best corrected distance visual acuity (BCDVA), distance corrected intermediate visual acuity (DCIVA) and distance corrected near visual acuity (DCNVA) were detected in both groups.The patient point spread function (PSF), modulation transfer function (MTF) cutoff frequency, Strehl ratio (SR), OQAS Ⅱ values at 100%, 20%, and 9% contrast (OV 100%, OV 20%, OV 9%) and objective scattering index (OSI) were measured by OQAS Ⅱ.Wavefront aberrations including total aberration (TA), total high order aberrations (tHOAs), spherical aberration, coma, trefoil aberration, total low order aberrations (tLOAs), defocus, and astigmatism were evaluated with the iTrace visual function analyzer.All aberrations were represented by root mean square.The visual acuity of operative eyes was measured with a phoropter, and defocus curves were drawn with visual acuity better than 0.5 LogMAR.The incidence of posterior capsular opacification (PCO) in the IOL region was quantitatively analyzed by Sellman method.Visual function was scored by visual function index (VF-14). This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of Nanjing Drum Tower Hospital, The Affiliated Hospital of Nanjing University Medical School (No.2018-219-01). Written informed consent was obtained from each subject prior to any medical examination.
ResultsOne year after the operation, UCIVA, UCNVA, DCIVA, and DCNVA of trifocal IOL group were significantly better than those of monofocal IOL group, and the differences were statistically significant (all at P<0.001). OQAS Ⅱ visual quality indicators showed that the MTF cutoff frequency, SR, OV 100%, and OSI values of trifocal IOL group were significantly higher than those of monofocal IOL group, showing statistically significant differences (all at P<0.001). No significant difference in wavefront aberrations was found between the two groups (all at P>0.05). Defocus curve showed that the LogMAR visual acuity of patients at -1.0 D, -1.5 D, -2.0 D, -2.5 D, -3.0 D, and -3.5 D (namely, 1 m, 66 cm, 50 cm, 40 cm, 33 cm, and 29 cm) in monofocal IOL group were significantly better than those in trifocal IOL group (all at P<0.05). There was a higher incidence of PCO in trifocal IOL group than monofocal IOL group, with a statistically significant difference ( χ 2 =41.0, P<0.001). The VF-14 score of trifocal IOL group was 87.99±1.09, which was significantly higher than 81.49±1.67 of monofocal IOL group ( t=10.301, P<0.001).
ConclusionsOne year after trifocal IOL implantation, the full range of vision, subjective and objective visual quality of eyes are better than eyes implanted with monofocal IOL.
