Resumen
HERNANDEZ-CHAVARRIA, Cesar; NAVARRO-SAUCEDO, Ricardo y CAMARA-CASTILLO, Héctor G.. Bilateral corneal wedge resection in a patient with high residual astigmatism after penetrating keratoplasty: A case report. Rev. mex. oftalmol [online]. 2020, vol.94, n.2, pp.90-93. Epub 25-Jun-2021. ISSN 2604-1227. https://doi.org/10.24875/rmo.m19000070.
Purpose:
To report a case of high astigmatism after penetrating keratoplasty treated with corneal wedge resection.
Observations:
We report our experience with a patient treated with corneal wedge excision for high astigmatism. A thin wedge of corneal tissue was removed from the donor-recipient interface. The wedge started on the flattest axis by keratometry and extended 20 degrees on each side; the same procedure was performed on the contralateral flat axis. The wound was closed with 10-0 nylon. We report the pre and post-operative topography.
Results:
The mean preoperative astigmatism by keratometry was 15 diopters (D). After wedge resection, the mean astigmatism was 1.7 D. The mean reduction in astigmatism by keratometry was of 13.3 D.
Conclusion:
Corneal wedge resection is a good option for high residual astigmatism after penetrating keratoplasty when the patient is not a candidate for other conservative treatments.
