Aurium变色人工晶状体植入术后对比敏感度和眩光对比敏感度的研究

Contrast sensitivity and glare contrast sensitivity in cataract patients treated with Aurium photochromic intraocular lens

目的研究Aurium变色人工晶状体对术后对比敏感度和眩光对比敏感度的影响。方法临床病例系列对比研究。选取2010年8月至2011年4月在南昌大学第二附属医院眼科就诊的白内障超声乳化联合人工晶状体植入术后患者，且随访资料完整的病例70例（眼），其中37例为Aurium（mode1400）变色人工晶状体组，33例为黄色蓝光滤过型IQ（SN60WF）人工晶状体组。观察患者术后3个月时的裸眼视力（UCVA），最佳矫正视力（BCVA），对比敏感度（CS）和眩光对比敏感度（GS）。结果二组患者术后3个月时的裸眼视力和最佳矫正视力差异均无统计学意义（P〉0．05）。Aurium组和IQ组在明适应、明适应眩光、暗适应条件下，两组之间的对比敏感度和眩光对比敏感度差异无统计学意义（P〉0．05），在暗适应眩光条件下Aurium组的眩光对比敏感度（空间频率3cpd、6cpd）要优于黄色蓝光滤过型IQ组，差异有统计学意义（P〈0．05）。结论植入Aurium变色人工晶状体术后患者的视力与黄色蓝光滤过型IQ人工晶状体的视力差异无统计学意义。Aurium变色人工晶状体在暗适应眩光条件下，空间频率（3cpd、6cpd）的眩光对比敏感度要优于黄色蓝光滤过型IQ人工晶状体。

Objective To evaluate contrast sensitivity （CS） and glare contrast sensitivity （GS） in patients who had undergone phacoemulsification with Aurium photochromic intraocular lens implantation. Methods Seventy patients who were operated with phacoemulsification and IOL implantation were enrolled. One group with 37 eyes implanted with Aurium photochromic intraocular lens, the other group with 33 eyes implanted with Alcon IQ intraocular lens. At 3 months postoperatively, uncorrected visual acuity （UCVA）, best corrected visual acuity （BCVA）, CS and GS were observed. Resuits The two lenses did not differ in UCVA and BCVA. There were no significant differences between two groups in photopic contrast sensitivity with no glare and with glare at all spatial frequencies. Similar at aU spatial frequencies in mesopic with no glare condition. The Aurium photochromic group showed significantly higher GS at 3.0 c/d and 6.0 c/d in mesopic with glare condition. Con- clusions The Aurium photochromic IOL offer visual acuity as well as the yellow blue light-filtering IQ IOL. The Aurium photochromic IOL offer higher GS at 3.0 c/d and 6.0 c/d in mesopic with glare condition.
