    摘要:

    目的:观察分别植入光变色人工晶状体、蓝光滤过人工晶状体、非蓝光滤过普通透明人工晶状体的老年白内障患者术后在不同对比度下的视力差别。

    方法:老年性白内障97例102眼随机分为3组,分别植入光变色人工晶状体(A组),蓝光滤过人工晶状体组(B组),普通人工晶状体(C组),术后3mo利用多功能视力测试仪对3组患者分别测试在明视及暗视环境下的对比度视力。

    结果:A组患者暗视时的3种对比度下的视力低于明视下的视力,但是在对比度下降到10%时这种差异才有统计学意义。B组和C组患者在3种对比度下暗视的对比度视力均低于明视下的对比度视力,差异有统计学意义。明视下A组和C组在100%,25%和10%对比度下的对比度视力没有统计学差异(P100%=1,P25%=1,P10%=0.86); A组在各对比度下的视力高于B组(P100%=0.010,P25%=0.004,P10%=0.041),B组在100%,25%对比度下的对比度视力低于C组,差异有统计学意义,在降至10%对比度时,两者差异无统计学意义(P100%=0.014,P25%=0.016,P10%=0.457)。暗视下A组和C组在100%、25%对比度下的对比度视力无明显差异,在10%对比度下的对比度视力A组高于C组,差异有统计学意义(P100%=1,P25%=0.111,P10%=0.029)。A组在3种对比度下的视力均高于B组,差异有统计学意义(P100%=0.000,P25%=0.000,P10%=0.001)。B组在100%,25%对比度下的对比度视力低于C组差异有统计学意义,在降至10%对比度时两者的对比度视力无统计学差异(P100%=0.000,P25%=0.039,P10%=0.596)。

    结论:在对于老年白内障患者光变色IOL在中高低对比度下比蓝光滤过IOL在暗视条件下具有更好的视觉质量。

    Abstract:

    AIM: To compare the contrast vision following implantation one of the following three intraocular lenses(IOLs): photochromic IOL, blue-light filtering IOL and conventional clear IOL.

    METHODS: Totally 97 cases(102 eyes)were randomly divided into 3 groups according to the type of IOL. Group A were implanted photochromic IOL, group B were implanted blue-light filtering IOL, group C were implanted conventional clear IOL. The contrast vision was evaluated in photopic condition three months after operation.

    RESULTS: In the scotopia condition, the contrast vision of the group A was lower than that in the photopic condition, but the contrast vision of the group A became statistically different until the contrast dropped to 10% contrast condition. The contrast vision of group B and group C were lower than that in the photopic condition and there had significant statistical difference. In the photopic condition: there was no significant statistical difference between group A and C in all the contrast level(P100%=1, P25%=1, P10%=0.86); the contrast vision of the group A was higher than group B in all the contrast level(P100%=0.010, P25%=0.004, P10%=0.041); In the 100%, 25% contrast condition, the contrast vision of the group B was lower than group C. Difference was statistically significant, but it became no statistically significant difference until the contrast dropped to 10% contrast condition(P100%=0.014, P25%=0.016, P10%=0.457). In the scotopia condition: there was no statistical difference between group A and group C in 100%, 25% contrast level, but in the 10% contrast condition the contrast vision of the group A was higher than group C. Difference was statistically significant(P100%=1, P25%=0.111, P10%=0.029). The contrast vision of the group A was higher than group B in all the contrast level. Difference was statistically significant(P100%=0.000, P25%=0.000, P10%=0.001). The contrast vision of group B was lower than group C in the 100%, 25% contrast condition. Difference was statistically significant, but it became no statistically different until the contrast dropped to 10% contrast condition(P100%=0.000, P25%=0.039, P10%=0.596).

    CONCLUSION: To the senile cataract patients, the photochromic Matrix 400 has better visual quality in scotopia lighting condition than the blue-light filtering people.
