SUMMARY

The surgically induced astigmatism was studied in two groups of 20 patients who underwent extracapsular cataract extraction. On one group (nylon group), nylon corneal sutures were employed. On another (poliester group), poliester corneal sutures were used. The comparison between two groups did not reveal statistic diference on the amount of the induced astigmatism. The decrease of surgically induced astigmatism on group nylon was statistically greater than poliester group at the 90-180 days postoperativelly. The sutures studied seem to induce similar amount of astigmatism, therefore, the decrease during the time seem to be diferent.
