摘要:
目的　对比分析四点和两点悬吊固定术后患者人工晶状体的倾斜和偏心情况及其与视力预后的关系。
方法　选取2021年6月至2022年4月于保定市第一中心医院眼科因各种原因行人工晶状体悬吊固定术的患者80例80眼作为研究对象。将患者随机分为2组，试验组41例41眼，均行四点悬吊固定术；对照组39例39眼，均行传统的两点悬吊固定术。术后至少随访6个月，记录两组术眼术前及末次随访裸眼视力（UCVA）、最佳矫正视力（BCVA），应用全景超声生物显微镜（UBM）测量两组术眼术后人工晶状体倾斜角度及偏心距离。比较两组术眼术前及末次随访UCVA、BCVA，术后人工晶状体倾斜角度与偏心距离，采用Pearson相关分析对倾斜角度及偏心距离与术后UCVA、BCVA的相关性进行分析。
结果　试验组和对照组术眼末次随访时UCVA和BCVA均优于术前（均为P<0.05）。试验组与对照组术眼术后UCVA相比，差异有统计学意义（t=-6.20，P=0.00），试验组术眼术后UCVA优于对照组；两组术眼术后BCVA相比，差异无统计学意义（t=-1.43，P=0.16）。试验组术眼术后人工晶状体水平倾斜度为0.70°±0.24°，垂直倾斜度为0.60°±0.16°；对照组术眼术后人工晶状体水平倾斜度为2.66°±1.40°，垂直倾斜度为3.76°±0.67°，两组比较差异均有统计学意义（t=-8.51、-29.42，P=0.00、0.00）。试验组术眼术后人工晶状体水平偏心距离为(0.24±0.10)mm，垂直偏心距离为（0.25±0.10）mm，对照组术后人工晶状体水平偏心距离为(0.85±0.77)mm，垂直偏心距离为（2.14±0.50）mm，两组比较差异均有统计学意义（t=-4.82、-21.68,P=0.00、0.00）。试验组术眼人工晶状体水平倾斜度及垂直倾斜度与术后UCVA和术后BCVA均不相关；水平偏心距离及垂直偏心距离与术后UCVA和术后BCVA均不相关（均为P>0.05）。对照组术眼人工晶状体水平倾斜度与术后UCVA和术后BCVA均呈正相关(均为P<0.05)；垂直倾斜度与术后UCVA和术后BCVA均不相关（均为P>0.05）,水平偏心距离与术后UCVA和术后BCVA均呈正相关(均为P<0.05)，垂直偏心距离与术后UCVA和术后BCVA均不相关（均为P>0.05）。
结论　四点悬吊固定术与传统两点悬吊固定术均可有效提高患者术后视力，但四点悬吊固定术后术眼人工晶状体倾斜和偏心程度更小。
Abstract:
Objective　To compare and analyze the tilt and decentration of the intraocular lens in patients receiving four-point and two-point suspension fixation, as well as their relationship with visual prognosis.
Methods　A total of 80 patients (80 eyes) who underwent intraocular lens suspension fixation at the Ophthalmology Department of Baoding No. 1 Central Hospital from June 2021 to April 2022 were selected as the subjects. These patients were randomly divided into the experimental group (41 patients, 41 eyes, underwent four-point suspension fixation) and the control group (39 patients, 39 eyes, underwent traditional two-point suspension fixation). They were followed up for at least 6 months after surgery to record their uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) before surgery and at the last follow-up. The tilt angle and decentration distance of the intraocular lens of patients in the two groups were measured after surgery by a panoramic ultrasound biomicroscope. The preoperative and last follow-up UCVA and BCVA of patients in the two groups, as well as tilt angle and decentration distance of the intraocular lens after surgery, were compared, and the correlation between tilt angle, decentration distance and postoperative UCVA, BCVA was analyzed by Person correlation analysis.
Results　The UCVA and BCVA at the last follow-up in the experimental group and control group were better than those before surgery (all P<0.05). The difference in postoperative UCVA between the experimental group and the control group was statistically significant (t=-6.20, P=0.00), and the experimental group had better postoperative UCVA than the control group. There was no statistically significant difference in postoperative BCVA between the experimental group and the control group (t=-1.43, P=0.16). The postoperative horizontal and vertical tilt angles of the intraocular lens in the experimental group were 0.70°±0.24° and 0.60°±0.16°, respectively; while those in the control group were 2.66°±1.40° and 3.76°±0.67°, respectively. The differences between the two groups were statistically significant (t=-8.51 and -29.42, P=0.00 and 0.00). The postoperative horizontal and vertical decentration distances of the intraocular lens in the experimental group were (0.24±0.10) mm and (0.25±0.10) mm, respectively, while those in the control group were (0.85±0.77) mm and (2.14±0.50) mm, respectively. The differences between the two groups were statistically significant (t=-4.82 and -21.68, P=0.00 and 0.00). In the experimental group, neither the horizontal and vertical tilt angles of intraocular lenses nor the horizontal and vertical decentration distances were correlated with postoperative UCVA and BCVA (all P>0.05). In the control group, the horizontal tilt angle of intraocular lenses was positively correlated with postoperative UCVA and BCVA (both P<0.05), while the vertical tilt angle was not correlated with postoperative UCVA and BCVA (both P>0.05); the horizontal decentration distance was positively correlated with postoperative UCVA and BCVA (both P<0.05), but the vertical decentration distance was not correlated with postoperative UCVA and BCVA (both P>0.05).
Conclusion　Both four-point suspension fixation and traditional two-point suspension fixation can effectively improve postoperative vision of patients, while the tilt and decentration of the intraocular lens are smaller after four-point suspension fixation.
