摘要
目的 用Pentacam三维眼前节分析系统测量研究一片式软襻与三片式硬襻两种丙烯酸酯折叠型人工晶状体(IOL)在囊袋内的稳定性和囊膜的透明性.方法 采用前瞻性研究,对51例双眼年龄相关性白内障患者行超声乳化白内障吸除联合IOL植入术,一只眼植入一片式软襻折叠型丙烯酸酯IOL SA60AT,对侧眼植入三片式硬襻折叠型丙烯酸酯IOL MA60BM.采用Pentacam三维眼前节分析系统测量术后1 d和1、6、12及24个月时IOL的偏心值、倾斜度、前房深度值以及晶状体后囊膜的光密度值.对所得数据两组之间比较采用配对t检验,组内不同时间点之间的比较采用重复测量资料方差分析.结果 分别比较一片式SA60AT组在不同时期的偏心值(0.37±0.16,0.36±0.15,0.36±0.16,0.37±0.15,0.38±0.16)、倾斜度(3.59±0.91,3.64±0.92,3.61±0.90,3.63±0.90,3.70±0.89)与后囊膜光密度值(22.20±3.99,21.96±4.00,22.40±4.03,22.53±4.00,22.95±3.87),差异均无统计学意义(F=1.938,0.785,1.814;P>0.05);比较三片式MA60BM组在不同时期的偏心值(0.34±0.14,0.33±0.14,0.34±0.14,0.35±0.14,0.36±0.14)、倾斜度(3.55±0.90,3.57±0.92,3.63±0.88,3.61±0.88,3.65±0.89),与后囊膜光密度值(21.14±3.88,20.98±3.87,21.23±3.83,21.59±3.82,21.65±3.87),差异均无统计学意义(F=1.004,0.525,1.963;P>0.05).在术后1 d和1、6、12及24个月,分别比较两组IOL的平均偏心值(t=0.802,0.701,0.588,0.898,0.631)、平均倾斜度(t=0.199,0.337,0.094,0.121,0.248)与后囊膜光密度值(t=1.214,1.119,1.334,1.082,1.517),差异均无统计学意义(P>0.05).一片式SA60AT组在不同时期的前房深度变化不大(3.90±0.99,3.88±1.07,3.91±1.01,3.90±1.02,3.92±1.02),差异无统计学意义(F=1.333,P>0.05);而三片式MA60BM组术后第1天的前房深度(4.37±1.02,3.90±0.98,3.95±0.99,3.93±0.96,3.97±0.99)大于术后其他时期(F=92.757,P<0.05),也大于一片式SA60AT组术后不同�
Objective To compare the amounts of intraocular lens (IOL) decentration and tilt, the anterior chamber depth (ACD) and the degree of posterior capsule opacification (PCO) using the Pentacam Scheimpflug System after cataract surgery between eyes with 1-piece acrylic IOL and 3-piece acrylic IOL Methods It was a perspective study. Fifty-one patients with bilateral senile cataract had implantation of a 1-piece SA60AT IOL in one eye and a 3-piece MA60BM IOL in the contralateral eye. The amount of IOL decentration, tilt, the ACD, and the degree of PCO was measured using the Pentacam Scheimpflug System 1 day and 1,6, 12 and 24 months postoperatively. Results There were no significant changes during the 24 m follow-up period in the decentration ( 0. 37 ± 0. 16, 0. 36 ± 0. 15, 0. 36 ± 0. 16, 0. 37 ± 0. 15,0. 38 ± 0. 16), tilt (3.59±0.91,3.64 ±0.92,3.61 ±0.90,3.63 ±0.90,3.70 ±0. 89)or PCO(22. 20 ±3.99,21.96 ±4. 00,22.40 ± 4. 03,22. 53 ± 4. 00,22. 95 ± 3. 87 ) in the 1 -piece SA60AT group ( F = 1. 938,0. 785,1. 814;P > 0. 05 ) or in the 3-piece MA60BM group (0. 34 ± 0. 14,0. 33 ± 0. 14,0. 34 ± 0. 14,0.35±0.14,0.36 ±0.14),(3.55 ±0.90,3.57 ±0.92,3.63 ±0.88,3.61 ±0.88,3.65 ±0.89),(21.14 ±3.88,20. 98 ±3. 87,21.23 ±3. 83,21.59 ±3. 82,21.65 ±3. 87) (F = 1. 004,0. 525,1. 963;P >0. 05). There was no significant difference between the two groups in IOL decentration (t = 0. 802,0. 701,0.588,0. 898,0.631), tilt (t =0. 199,0.337,0.094,0. 121,0.248) or PCO(t = 1.214,1. 119,1.334,1. 082,1. 517)at any time points (P > 0. 05 ). The ACD did not change after the surgery in the 1-piece group (3.90 ±0. 99,3.88 ± 1.07,3.91 ± 1.01,3.90 ± 1.02,3.92 ± 1.02) (F= 1. 333,P >0. 05) but was significantly deeper in the 3-piece group ( 4. 37 ± 1.02,3.90 ± 0. 98,3.95 ± 0. 99,3.93 ± 0. 96,3.97 ± 0. 99 ) ( F = 92. 757, P < 0. 05 ) one day after the operation. The ACD was more shallow in the 1-piece SA60AT group than in the 3-piece MA
