We conducted a clinical retrospective study in which the records of 350 consecutive extracapsular cataract operations were reviewed in order to compare two cataract extraction techniques: planned extracapsular cataract extraction (PECCE) and phakoemulsification (PKE) with and without intraocular lens implantation. The patients in the PKE group experienced significantly better vision overall. However, when an adjustment was made for the difference in age between patient populations there was no significant difference in the percentage of patients achieving good vision between the two groups. Similarly, there was no statistically significant difference in the total number of operative or postoperative complications. The patients in the PKE group required less time for refraction to stabilize and averaged less postoperative astigmatism. Both of these differences were statistically significant even after an adjustment was made for the difference in age between populations. The presence or absence of an intraocular lens had no effect on the findings.
我们进行了一项临床回顾性研究，回顾了连续350例囊外白内障手术的记录，以比较两种白内障摘除技术：计划性囊外白内障摘除术（PECCE）和有或无人工晶状体植入的超声乳化白内障吸除术（PKE）。PKE组患者总体视力明显更好。然而，在对患者群体之间的年龄差异进行调整后，两组中视力良好的患者百分比没有显著差异。同样，手术或术后并发症的总数也没有统计学上的显著差异。PKE组患者屈光稳定所需时间更短，术后散光平均度数更低。即使在对群体之间的年龄差异进行调整后，这两个差异在统计学上仍然显著。人工晶状体的有无对研究结果没有影响。
