Abstract

PURPOSE

To compare the development of glistenings after implantation of a hydrophobic acrylic intraocular lens (IOL) (AcrySof SA60AT) and a hydrophilic IOL (BL27) and evaluate the effect on corrected distance visual acuity (CDVA) and contrast sensitivity 9 years postoperatively.

SETTING

St. Erik Eye Hospital, Stockholm, Sweden.

DESIGN

Prospective randomized clinical trial.

METHODS

One of 3 experienced cataract surgeons performed standard phacoemulsification in 1 eye of each patient. The patients were randomized to implantation of a hydrophobic acrylic IOL or a hydrophilic acrylic IOL. Both IOLs had sharp posterior edges. The CDVA and contrast sensitivity were measured 9 years postoperatively. Scheimpflug images of the IOLs were obtained to analyze glistenings, which were graded subjectively at the slitlamp and quantified objectively with digital image analysis using computer software.

RESULTS

Seventy-eight of the 120 patients were available for the 9-year follow-up examination. Patients with the hydrophilic IOL had statistically significantly fewer glistenings (P < .001). The development of glistenings was not correlated with IOL power, CDVA, or contrast sensitivity.

CONCLUSIONS

After 9 years, the hydrophobic IOL developed more glistenings than the hydrophilic IOL. Glistenings did not affect CDVA or contrast sensitivity.

摘要

目的

比较疏水性丙烯酸人工晶状体(IOL)(AcrySof SA60AT)和亲水性IOL(BL27)植入后晶状体闪光的发展情况,并评估术后9年对矫正远视力(CDVA)和对比敏感度的影响。

设置

瑞典斯德哥尔摩圣埃里克眼科医院。

设计

前瞻性随机临床试验。

方法

3名经验丰富的白内障外科医生之一为每位患者的一只眼睛进行标准超声乳化白内障吸除术。患者被随机分配植入疏水性丙烯酸IOL或亲水性丙烯酸IOL。两种IOL均具有锐利的后缘。术后9年测量CDVA和对比敏感度。获取IOL的Scheimpflug图像以分析晶状体闪光,在裂隙灯下进行主观分级,并使用计算机软件通过数字图像分析进行客观量化。

结果

120例患者中有78例可进行9年的随访检查。亲水性IOL患者的晶状体闪光在统计学上显著较少(P <.001)。晶状体闪光的发展与IOL屈光度、CDVA或对比敏感度无关。

结论

9年后,疏水性IOL比亲水性IOL产生更多的晶状体闪光。晶状体闪光不影响CDVA或对比敏感度。
