Refractive changes after six cataract surgery procedures with intraocular lens implantation were assessed; namely, (1) 11 mm incision with running suture closure (n = 25 eyes), (2) 6.5 mm incision with running suture closure (n = 23). (3) 6.5 mm incision with horizontal suture closure (n = 21), (4) 6.5 mm incision without suture closure (n = 40), (5) 5.5 mm incision without suture closure (n = 46), and (6) 3.2 mm incision without suture closure (n = 46). The axis-based keratometric cylinder, absolute value of the induced cylinder vector, and spherical equivalent of the refractive power were analyzed up to 6 months after surgery. Refractive changes did not reach a stable state at 3 months postoperatively for the 11 mm and 6.5 mm running suture closure groups, but they stabilized at 3 months postoperatively for the 6.5 mm horizontal suture and sutureless closure groups, at 1 month postoperatively for the 5.5 mm sutureless closure group, and at 2 weeks postoperatively for the 3.2 mm sutureless closure group. It is concluded that the timing of refractive stabilization differs significantly among procedures, and smaller incisions with wound closure methods which do not exert a vertical force cause fewer postoperative refractive changes.
评估了六种白内障手术联合人工晶状体植入术后的屈光变化；即，（1）11毫米切口连续缝合关闭（n = 25只眼），（2）6.5毫米切口连续缝合关闭（n = 23）。（3）6.5毫米切口水平缝合关闭（n = 21），（4）6.5毫米切口不缝合关闭（n = 40），（5）5.5毫米切口不缝合关闭（n = 46），以及（6）3.2毫米切口不缝合关闭（n = 46）。分析了术后6个月内基于轴的角膜散光柱镜、诱导散光柱镜矢量的绝对值以及屈光力的球镜当量。11毫米和6.5毫米连续缝合关闭组术后3个月屈光变化未达到稳定状态，但6.5毫米水平缝合和不缝合关闭组术后3个月屈光变化稳定，5.5毫米不缝合关闭组术后1个月屈光变化稳定，3.2毫米不缝合关闭组术后2周屈光变化稳定。得出的结论是，不同手术方式屈光稳定的时间差异显著，较小的切口以及不施加垂直力的伤口闭合方法导致的术后屈光变化较少。
