To prospectively compare the clinical results of two cataract surgery procedures through a 4.0-mm incision, differing only in the wound location (superior or lateral).
168 eyes with cataract were randomly assigned to either procedure. Except for incision location, surgical methods were identical. Uncorrected visual acuity, keratometry and postoperative astigmatism were analyzed up to six months for after surgery.
Both groups had similar uncorrected visual acuity. Eyes in the superior incision group had significantly larger "against-the-rule" changes than those in the lateral incision group, and differences were significant at all measurement points from one week through six months after surgery. Patients with preoperative "with-the rule" astigmatism had smaller postoperative astigmatism after a superior incision and those with preoperative "against-the rule" astigmatism had less postoperative cylinder after a lateral incision. Differences between these groups were significant.
Both procedures gave satisfactory clinical results. Postoperative astigmatism could depend on the preoperative astigmatism and the wound location.
前瞻性比较两种经4.0毫米切口的白内障手术的临床结果，这两种手术仅在切口位置（上方或外侧）有所不同。
168例白内障患者的眼睛被随机分配至两种手术方式。除切口位置外，手术方法相同。对术后长达六个月的未矫正视力、角膜曲率测量和术后散光进行分析。
两组的未矫正视力相似。上方切口组的眼睛“逆规”变化明显大于外侧切口组，且在术后一周至六个月的所有测量点差异均有统计学意义。术前有“顺规”散光的患者在上方切口后术后散光较小，术前有“逆规”散光的患者在外侧切口后术后柱镜度数较小。这些组间差异有统计学意义。
两种手术方式均取得了满意的临床结果。术后散光可能取决于术前散光和切口位置。
