Short-term Effect of Suture Tension after Scleral Tunnel Incision in Posterior Chamber Lens Implantation on Preexisting Astigmatism

ABSTRACT

In this two-month prospective study, reduction of preexisting astigmatism in 35 eyes was attempted by tension control of a mattress. In the first group, which had WTR astigmatism over 1.5 diopter(D) the wound was closed with loose mattress suture(MS). This reduced WTR astigmatism 1.52 D at 2 months. In the second group(WTR astigmatism, under 1.5 D)closed with a adaptation suture, the preexisting WTR astigmatism did not show a significant shift toward ATR astigmatism. In the third group closed with a tight MS, the preexisting ATR astigmatism was not significantly increased.
