The authors evaluate the results of keratometry in a group of 235 patients after surgery of cataract who were operated by the technique of posterior limbal and scleral tunnel section by the same surgeon. Posterior limbal section induced after surgery astigmatism, on average +4.0 D in the median section, the scleral tunnel section about +2.0 D. Astigmatism after the posterior limbal section improved spontaneously during the fourth month after surgery; if it persisted, it improved after discontinuation of the suture. Slight astigmatism after the posterior limbal section developed easily after four months following operation into astigmatism against the rule. Astigmatism after a scleral tunnel section disappeared after the fourth month following operation but did not develop against the rule. Both types of sections induced after surgery similar but negligible changes of the spheral corneal equivalent.
作者评估了同一外科医生采用后缘角膜和巩膜隧道切口技术对235例白内障手术后患者进行角膜曲率测量的结果。后缘角膜切口术后导致散光，在中间切口平均为+4.0 D，巩膜隧道切口约为+2.0 D。后缘角膜切口术后的散光在术后第四个月自发改善；如果持续存在，则在拆除缝线后改善。后缘角膜切口术后的轻度散光在术后四个月后容易发展为逆规散光。巩膜隧道切口术后的散光在术后第四个月消失，但未发展为逆规散光。两种切口术后均引起相似但可忽略不计的等效球镜角膜变化。
