Abstract/OtherAbstract:
Background: To determine the alterations in the corneal topography after pars planavitrectomy with the system of 20- and 25-gauge. Methods: A total of 29 patients with vitreous hemorrhage. The first group (17 patients) had to undergo a pars planavitrectomy with the 20-gauge system, whereas the second (12 patients) had the pars planavitrectomy with the 25-gauge system. The corneal topography was analyzed in the pre-operation, in the first, third, and sixth months in the post-operation. Results: the group which underwent the standartvitrectomy registered a statistically significant difference in the keratometric difference (dK) in the first month compared to the pre-operation (p < 0,000), first month with the third month (p < 0,020), first month and sixth month (p < 0,008). In the 25-gauge system group significant statistical alterations did not occur. Conclusion: astigmatism occurs in the first month post vitrectomy standard. The 25-gauge systemis notinducedastigmatism.
