摘要
目的了解白内障小切口术后角膜地形图与角膜曲率的变化。方法用角膜地形图与角膜曲率计对３６例（３８只眼）白内障小切口术后进行１周、１个月、３个月、６个月及１年定期随访。结果术后１周角膜形态有轻度中央部和周边部陡峭或平坦，１个月后恢复至术前状态，长期随访无变化。角膜曲率计测量结果与角膜地形图有差异。结论小切口术后散光小，视力恢复快且稳定。角膜地形图比角膜曲率计更可靠、更准确地反映角膜曲率的变化。
Objective The study was designed to investigate the corneal topographical and corneal curvature changes of small incision in cataract surgery. Methods 38 eyes of 36 patients who had undergone small incision cataract surgery were followed up at one week and one, three, six and twelve months postoperatively by corneal topography and keratometer. Results At one week postoperatively, there was slight steeping or flattening at the center and peripheral cornea, but the change was recovered to the preoperative state after one month. No significant changes had been observed after a long term observation. The result of keratometer was different from that of topography. Conclusions It is clearly demonstrated that smaller wound incision produces less astigmatism, faster postoperative recovery and more stable refraction. The results of corneal topography reflect curvature changes more reliably and precisely than that of keratometer, and topography is of great value in cataractous surgical evaluation.
