摘要:
目的　比较Ａ超与光学相干生物测量仪（ＩＯＬＭＡＳＴＥＲ）测量低信噪比（ｓｉｇｎａｌｔｏｎｏｉｓｅｒａｔｉｏ，ＳＮＲ）高度近视眼人工晶状体（ｉｎｔｒａｏｃｕｌａｒｌｅｎｓ，ＩＯＬ）度数的精确性。方法　对２０１５年３月至２０１６年２月间在我院行白内障超声乳化联合ＩＯＬ植入手术并且眼轴长度大于２６ｍｍ的高度近视患者５７例（６９眼）进行回顾性研究。ＳＮＲ≤２组１１眼、ＳＮＲ＞２～５组２３眼、ＳＮＲ＞５～１０组２０眼，无法用ＩＯＬＭＡＳＴＥＲ检出的病例设为Ａ超测量组１５眼。分别用ＩＯＬＭＡＳＴＥＲ或接触式Ａ超测算度数，计算公式采用ＨＯＬＬＡＤＡＹ-１公式，并按各自方法植入同一类型ＩＯＬ，术后３个月分别计算各组的平均绝对屈光误差值。结果　ＳＮＲ＞５～１０组、ＳＮＲ＞２～５组、ＳＮＲ≤２组、Ａ超测量组的绝对屈光误差值分别为（０．４４±０．１８）Ｄ、（０．４６±０．２６）Ｄ、（０．６９±０．２２）Ｄ、（０．８１±０．２９）Ｄ，其中ＳＮＲ＞２～５组及ＳＮＲ＞５～１０组分别与其他２组比较，差异均有统计学意义（均为Ｐ＜０．０５），而ＳＮＲ＞２～５组与ＳＮＲ＞５～１０组以及ＳＮＲ≤２组与Ａ超测量组之间差异均无统计学意义（均为Ｐ＞０．０５）。结论对于低ＳＮＲ的高度近视眼患者，采用ＩＯＬＭＡＳＴＥＲ测算ＩＯＬ度数比传统Ａ超方式具有更高的精确性。
Abstract:
Objective To compare the accuracy of A-scan and IOL Master in measuring intraocular lens ( IOL) power of high myopia with low signal to noise ratio ( SNR) . Methods From March 2015 to February 2016,69 eyes of 57 patients of high myopia with axial length greater than 26 mm who received phacoemulsification with IOL implantation in our hospital were enrolled. According to the SNR , eyes were assigned to SNR¡?2 goup , >2 -5 group and > 5 - 10 group , and those eyes which could not be measured by IOL Master were assigned to A-scan group. A1l eyes were implanted same type of artificial IOL which were calculated through HOLLADAY-I. The mean absolute error was evaluated at 3 months after the operation. Results The mean absolute error in SNR > 5 - 10 group , > 2 - 5 goup ,¡Ü2 group and contact A-scan group were (0. 44 +0. 18 ) D, ( 0. 46 +0. 26) D. (0. 69 + 0. 22 ) D and ( 0. 81 + 0. 29 ) D, respectively. The SNR > 2 - 5 group and SNR > 5 - 10 group were respectively compared with the other two groups,the differences were statistically siguficant ( all P < 0. 05 ) . There was no siguficant difference between SNR > 2 - 5 group and SNR > 5 - 10 ~oup , or between SNR¡?2 group and contact A-scan group ( all P > 0. 05 ) . Conclusion The calculation of IOL power by IOL Master is more accurate than that by contact A-scan for high myopia with low SNR.
