The aim of this study was to highlight the structural changes in patients with cataract following surgery and the repercussions on the anterior pole.
A total of 83 patients diagnosed with cataract who underwent uneventful phacoemulsification was included. Every patient was examined one week prior to and two weeks after the surgery. Pre- and postoperative assessment included examination of the anterior and posterior segment, keratometry, and optical biometry.
The pre- vs. postoperative axial length (AL) mean difference was 0.07 ± 0.18 mm ( < 0.001).The mean difference of the postoperative anterior chamber depth (ACD) vs. preoperative ACD values (1.11 ± 0.50 mm) was also statistically significant ( < 0.001). The linear regression function postoperative central corneal thickness (CCT) = 0.9004 × (preoperative CCT) + 0.0668, where it characterized a reduced positive correlation (R) of 68.89% between the postoperative CCT and preoperative CCT. The mean pre-/post-operative differences in the K1 values were 0.08 ± 0.38 D, with a statistically significant difference between the two datasets ( = 0.0152). The mean pre/postoperative difference in the K2 values was 0.002 ± 0.58 D ( = 0.4854).
ACD deepened significantly postoperatively. Regarding AL, there was a decrease after surgery, and a very good positive correlation between the post and preoperative values. The CCT values decreased with age. The 2.2-mm corneal incision during cataract surgery resulted in a relatively small postoperative residual astigmatism.
本研究的目的是突出白内障患者术后的结构变化以及对前极的影响。
纳入83例诊断为白内障且接受了顺利的超声乳化手术的患者。每位患者在手术前一周和手术后两周接受检查。术前和术后评估包括眼前段和眼后段检查、角膜曲率测量和光学生物测量。
术前与术后眼轴长度（AL）的平均差值为0.07±0.18毫米（P<0.001）。术后前房深度（ACD）与术前ACD值的平均差值（1.11±0.50毫米）也具有统计学意义（P<0.001）。线性回归函数为术后中央角膜厚度（CCT）=0.9004×（术前CCT）+0.0668，其中术后CCT与术前CCT之间的正相关性降低，相关系数（R）为68.89%。K1值术前/术后的平均差值为0.08±0.38 D，两个数据集之间存在统计学显著差异（P=0.0152）。K2值术前/术后的平均差值为0.002±0.58 D（P=0.4854）。
术后ACD显著加深。关于AL，手术后有所缩短，且术前和术后值之间存在非常良好的正相关性。CCT值随年龄降低。白内障手术中2.2毫米的角膜切口导致术后残余散光相对较小。
