Comparison of suturing techniques in keratoplasty for keratoconus.

The results of 48 consecutive penetrating keratoplasties for keratoconus were analyzed. The overall success rate was 93% clear grafts and there was no significant difference in the percentage of success, the amount of the spherical equivalent of the myopia, or the types of complications between the technique using 9-0 interrupted virgin silk sutures and 10-0 monofilament nylon running suture. The average astigmatic error was 25% less in the series employing the running suture.
