目的观察白内障患者的角膜厚度在超声乳化术前后的变化。方法随机抽取在我院手术的老年性白内障患者156例(178眼),分别于术前及术后第1、2、3天及1、3个月采用超声角膜测厚仪测量中央及周边角膜厚度,并进行统计学分析。结果术后第1天角膜增厚最明显,第2、3天逐渐减轻,3d间角膜厚度的差异有统计学意义(P<0.01),术后1个月逐渐恢复,3个月完全恢复,1、3个月角膜厚度的差异无统计学意义(P>0.05)。术后角膜增厚以上方周边角膜为重,中央部次之,两个部位之间的差异有统计学意义(P<0.01)。结论白内障超声乳化联合人工晶状体植入术后角膜厚度增加,但随时间推移逐渐恢复,3个月时恢复至术前水平。
Objective To observe the changes of corneal thickness before and after phacoemulsification in cataract patients. Methods A total of 156 patients (178 eyes) with senile cataract who underwent surgery in our hospital were randomly selected. The corneal thickness of the central and peripheral cornea was measured by using echocardiography before operation, at the first, second, third, and third postoperative days respectively Thickness, and statistical analysis. Results The corneal thickening was most obvious on the first postoperative day, and gradually decreased on the second and third days. The difference of the corneal thickness between the two groups was statistically significant (P <0.01), gradually recovered at 1 month and recovered completely at 3 months, There was no significant difference in corneal thickness between 1 and 3 months (P> 0.05). Corneal thickening was followed by the cornea above the top, followed by the central part, the difference between the two parts was statistically significant (P <0.01). Conclusions Corneal thickness increases after phacoemulsification combined with intraocular lens implantation but gradually recovers over time, returning to preoperative levels at 3 months.
