目的:研究小切口白内障手术后角膜形态变化特点。方法:用角膜地形图对42例(48只眼)白内障小切口手术患者进行观察及分析术前3天、术后1周、1个月、3个月的角膜地形图变化。结果:小切口人工晶体植入术由于手术切口小,其对角膜散光的影响显得不明显。结论:角膜地形图形象反映角膜形态变化,并可定量分析角膜形态的变化,对术前术后角膜散光作出准确判断,对白内障手术具有极大指导意义。
Objective: To study the changes of corneal morphology after small incision cataract surgery. Methods: Corneal topography was used to observe the changes of corneal topography in 42 patients (48 eyes) with small incision of cataract. The changes of corneal topography were observed 3 days before operation, 1 week, 1 month and 3 months after operation. Results: Small incision IOL implantation due to small incision, its impact on corneal astigmatism is not obvious. CONCLUSION: Corneal topography reflects the change of corneal shape, and can quantitatively analyze the change of corneal shape. It can make accurate judgment of preoperative and postoperative corneal astigmatism and has great guiding significance for cataract surgery.
