A study to determine the correlation between intraoperative quantitative keratometry and one day postoperative office keratometry was performed. Prior reports have failed to demonstrate a positive statistical relationship between surgical and postoperative keratometry, weakening the value of quantitative intraoperative keratometry. Careful control of variables at surgery, however, can allow for positive keratometric correlation. The data of the present study revealed no statistical difference between intraoperative and one day postoperative corneal astigmatism when intraocular pressure was established at a standard physiologic level prior to final suture closure of the scleral pocket wound. When intraocular pressure was not controlled at the time of wound closure, intraoperative and postoperative corneal cylinder were statistically dissimilar. Operative quantitative keratometry, performed with tight control of variables, appears to play a vital role in reducing iatrogenic cylinder in the early postoperative phase of cataract rehabilitation.
一项旨在确定术中定量角膜曲率测量与术后一天门诊角膜曲率测量之间相关性的研究得以开展。先前的报告未能证明手术与术后角膜曲率测量之间存在统计学上的正相关关系，这削弱了定量术中角膜曲率测量的价值。然而，在手术过程中仔细控制变量，可以实现角膜曲率测量的正相关。本研究数据显示，在巩膜瓣伤口最终缝合前将眼压设定在标准生理水平时，术中与术后一天的角膜散光无统计学差异。当伤口闭合时眼压未得到控制时，术中与术后的角膜柱镜度数在统计学上存在差异。在严格控制变量的情况下进行的手术定量角膜曲率测量，似乎在白内障康复术后早期减少医源性散光方面起着至关重要的作用。
