A scleral pocket incision technique with continuous suture closure was used in a series of 40 patients undergoing phacoemulsification with posterior chamber lens implantation to determine the change in astigmatic error induced by surgery. Intraoperative keratometry was not used and no attempt to estimate the induced cylinder at the time of surgery was made. Keratometric analysis of postoperative astigmatism in the present study indicated that shortly after surgery there was an induced with-the-rule shift that gradually abated to a minimal against-the-rule change after the wound was fully healed, regardless of how tight the wound was closed at the time of surgery. It appears that intraoperative keratometry would have had no bearing on the final astigmatic outcome.
在一系列40例接受超声乳化白内障吸除联合后房型人工晶状体植入术的患者中，采用巩膜隧道切口技术并连续缝合关闭切口，以确定手术引起的散光误差变化。术中未使用角膜曲率计，且在手术时未尝试估计诱导的柱镜度数。本研究对术后散光的角膜曲率分析表明，术后不久出现了顺规性散光偏移，随着伤口完全愈合，这种偏移逐渐减轻至最小的逆规性变化，无论手术时伤口缝合得有多紧。似乎术中角膜曲率计对最终的散光结果没有影响。
