The natural history of corneal astigmatism in 118 eyes following extracapsular cataract extraction and PC IOL implantation demonstrated that the average surgery induced with-the-rule astigmatism of 3.37D one week after the operation declined at a rate of 0.60, 0.63 and 0.39D during the 1st, 2nd and 3rd months respectively, indicating that the with-the-rule astigmatism of 2.00-3.00D would be corrected spontaneously to the normal or physiological status. The relationship between the changes in astigmatism and postoperative vision and the intraocular pressure was discussed.
118只眼行白内障囊外摘除联合后房型人工晶状体植入术后角膜散光的自然病史表明，术后1周平均手术诱导的顺规散光为3.37D，在第1、2、3个月分别以0.60、0.63和0.39D的速率下降，这表明2.00 - 3.00D的顺规散光将自发矫正至正常或生理状态。文中还讨论了散光变化与术后视力及眼压之间的关系。
