摘要
目的采用Allegro Oculyzer眼前节诊断系统测量激光原位角膜磨镶术(LASIK)前后前房相关参数并分析其变化。方法前瞻性自身对照研究。应用Allegro Oculyzer系统分析39例(77眼)近视患者LASIK手术前及手术后7d角膜后表面曲率、前房容积(ACV)、各象限房角(ACA)、中央及周边前房深度(ACD)等变化。采用Wilconxon符号秩和检验。结果LASIK术前角膜后表面曲率,ACV,ACA(平均、上、下、鼻、颞),ACD(中央、上方周边、下方周边、鼻侧周边、颞侧周边)分别为-(6.19±0.23)D,(207±30.2)mm3,(40.4±4.53)°、(33.8±8.57)°、(33.9±4.72)°、(42.9±5.00)°、(42.9±4.68)°,(3.23±0.23)mm、(1.51±0.20)mm、(1.43±0.24)mm、(0.98±0.20)mm、(1.03±0.21)mm;术后7d则变为(-6.19±0.22)D,(197±31.1)mm°,(40.6±4.91)°、(34.8±8.15)°、(33.9±4.72)°、(41.3±5.32)°、(43.5±4.25)°,(3.13-±0.24)mm、(1.45±0.22)mm、(1.36±0.28)mm、(0.93±0.20)mm、(0.96±0.21)mm,其中手术前后ACV、ACD均较术前减小,差异有统计学意义(Z=-5.466、-7.352、-2.614、-2.546、-2.203、-3.327,P〈0.05),而ACA变化则无统计学意义。结论LASIK术后早期ACV、中央ACD及周边ACD较术前均减小,其中中央ACD减小较周边更为明显。
Objective To investigate early changes in anterior chamber parameters with the Allegro Oeulyzer system after laser in situ keratomileusis (LASIK). Methods Thirty-nine patients (77 eyes) were recruited for this prospective self-control study. An Allegro Oculyzer anterial segment analysis system was used to measure the parameters of the anterior chamber (i.e. the anterior chamber volume, the anterior chamber angle of the four quadrants, and the central and peripheral anterior chamber depths) before and after LASIK. The Wilcoxon signed rank test was used for data analysis. Results Before surgery, the posterior corneal tangential curvature, the anterior chamber volume, the anterior chamber angle (average/superior/inferior/nasal/temporal), and the central and peripheral anterior chamber depths (superior/inferior/nasal/temporal) were:-(6.19±0.23)D,(207±30.2)mm3,(40.4±4.53)°、(33.8±8.57)°、(33.9±4.72)°、(42.9±5.00)°、(42.9±4.68)°,(3.23±0.23)mm、(1.51±0.20)mm、(1.43±0.24)mm、(0.98±0.20)mm、(1.03±0.21)mm; respectively. Seven days after the surgery, the parameters had changed to:(-6.19±0.22)D,(197±31.1)mm°,(40.6±4.91)°、(34.8±8.15)°、(33.9±4.72)°、(41.3±5.32)°、(43.5±4.25)°,(3.13-±0.24)mm、(1.45±0.22)mm、(1.36±0.28)mm、(0.93±0.20)mm、(0.96±0.21)mm, respectively. The differences between the anterior chamber volume and the central and peripheral anterior chamber depths were statistically significant (Z=-5.466, -7.352, -2.614, -2.546, -2.203, -3.327, P〈0.05). Conclusion The anterior chamber volume and the central and peripheral anterior chamber depths decreased soon after LASIK was performed with the Allegro Oculyzer system. The change in the central anterior chamber depth was greater than that of the peripheral anterior chamber depth.
