【摘要】：目的通过白内障术后双眼分别植入光致变色型人工晶状体(intraocular lens,IOL)Matrix400与蓝光滤过型黄色IOL(SN60AT),对比研究两种IOL在不同光照条件下对人眼色觉的影响。方法自身双眼对照临床研究。收集2010年10月至2012年1月在我院确诊为双眼年龄相关性白内障并行白内障超声乳化摘出联合IOL植入术的患者25例,右眼白内障超声乳化摘出术后植入光致变色型IOL,左眼植入黄色IOL。术后3个月检查裸眼视力、最佳矫正视力及黄斑中央区视网膜厚度,采用Farnsworth-Munsell 100 Hue色棋排列法在三种不同的色觉检查环境下检查单眼色觉功能,并对主观视觉感受进行问卷调查。结果术后3个月双眼裸眼视力、最佳矫正视力以及黄斑中央区视网膜厚度差异均无统计学意义(均为P0.05)。明环境+紫外线环境及无紫外线明环境(400 Lux)下,左右眼总错误平方根及各色棋盒错误平方根差异均无统计学意义(均为P0.05)。中间视觉环境(30 Lux)下,左右眼第三色棋盒Box3(含蓝色)错误平方根差异有统计学意义(P=0.009),表现为植入Matix400 IOL眼具有更低的错误分数;双眼总错误平方根及余色棋盒的错误平方根差异均无统计学意义(均为P0.05)。25例患者中6例表示在平日晴朗天气外出时需要配戴太阳镜,但阳光刺激引起的左右眼不适程度没有明显差别;3例患者在明亮室内环境能感觉到左眼视野稍偏黄色,但无因此而感觉不适。结论在有紫外线的明环境下和无紫外线明环境下植入光致变色型IOL眼和植入蓝光滤过型黄色IOL眼具有相同的辨色能力;在较暗的中间环境下光致变色型IOL眼显示出更佳的辨别蓝色功能;在日常生活中植入光致变色型IOL眼可能具有更少的"黄视"干扰。
[Abstract]:Objective to investigate the effects of two kinds of IOL on human eye color perception after cataract surgery by implantation of photochromic intraocular lens (intraocular lens,IOL) Matrix400 and blue light filtered yellow IOL (SN60AT) respectively. Methods the clinical study was carried out by self-binocular control. From October 2010 to January 2012, 25 patients with binocular age-related cataract and phacoemulsification combined with IOL implantation were collected. Right eye phacoemulsification after phacoemulsification implantation photochromic IOL, and yellow IOL. in left eye The naked visual acuity, the best corrected visual acuity and the retinal thickness of the central macular area were examined 3 months after operation. The monocular color vision function was examined by Farnsworth-Munsell 100 Hue color chess arrangement under three different color vision conditions, and the subjective visual perception was investigated by questionnaire. Results there was no significant difference in visual acuity, best corrected visual acuity and retinal thickness of central macular area 3 months after operation (P0.05). There was no significant difference between the square root of left and right eye errors and the square root of different color chess box errors (P0.05) in the ultraviolet environment and the non-ultraviolet environment (400 Lux). In the middle visual environment (30 Lux), the difference of the square root of Box3 (including blue) error in the left and right eyes was statistically significant (P0. 009), which showed that the implanted Matix400 IOL eyes had lower error score. There was no significant difference in the error square root between the two groups (P0.05). 6 out of 25 patients indicated that they needed to wear sunglasses when they went out on a sunny day. However, there was no significant difference in the degree of left and right eye discomfort caused by sunlight stimulation in 3 cases. The visual field of left eye was slightly yellow in bright indoor environment, but there was no discomfort. Conclusion the photochromic IOL eyes and the blue filtered yellow IOL eyes have the same color discrimination ability in the ultraviolet and no UV environment. The photochromic IOL eyes showed better blue discrimination function in the dark middle environment, and the photochromic IOL eyes implanted in daily life may have less "yellow vision" interference.
