Radial suturing of 6.5-millimeter scleral tunnel incisions following cataract surgery can create significant with-the-rule astigmatism in the immediate postoperative period. Because of the significant visual distortion and slow visual recovery seen with radial suturing, this study was undertaken to compare two other suturing techniques which induce lesser amounts of with-the-rule astigmatism in the immediate postoperative period.
The refractive behavior of eyes closed with loose radial sutures and with horizontal sutures was compared to the behavior of eyes closed with the more traditional "tight" radial sutures following phacoemulsification surgery.
Eyes sutured with loosely tied radial sutures demonstrated minimal with-the-rule cylinder immediately following surgery (1.25 D) and showed a more rapid stabilization of astigmatism than did the eyes tied with tight radial sutures, 2 months versus up to 6 months. However, the eyes tied with horizontal sutures, which showed no induced with-the-rule astigmatism at the time of surgery, showed even more rapid stabilization between 5 days and 1 month from the time of surgery.
To get the most rapid visual rehabilitation following cataract surgery, a wound closure which generates no induced with-the-rule cylinder such as horizontal sutures would be required.
白内障手术后对6.5毫米巩膜隧道切口进行放射状缝合，在术后即刻可产生显著的顺规散光。由于放射状缝合会导致明显的视觉扭曲且视觉恢复缓慢，因此开展本研究以比较其他两种在术后即刻引起较少顺规散光的缝合技术。
将采用宽松放射状缝线和水平缝线缝合的眼睛的屈光行为，与采用更传统的“紧密”放射状缝线缝合的眼睛在超声乳化手术后的行为进行比较。
采用宽松放射状缝线缝合的眼睛在手术后即刻表现出最小的顺规柱镜度数（1.25 D），且与采用紧密放射状缝线缝合的眼睛相比，散光稳定得更快，分别为2个月和长达6个月。然而，采用水平缝线缝合的眼睛在手术时未出现诱导性顺规散光，在术后5天至1个月之间散光稳定得更快。
为了在白内障手术后实现最快的视觉康复，需要一种不产生诱导性顺规柱镜度数的伤口闭合方式，如水平缝线缝合。
