Reportar un caso con astigmatismo alto residual posterior a queratoplastia penetrante tratado con resección en cuña corneal. observaciones: Reportamos nuestra experiencia con un paciente tratado con resección en cuña por astigmatismo residual posterior a queratoplastia penetrante. Se retiró una cuña delgada de tejido corneal justo por dentro de la interface donador-receptor. La cuña se inició en el eje más plano queratométrico y se extendió 20 grados a cada lado. Se realizó el mismo procedimiento en el eje plano contralateral. La herida se cerró con nylon 10-0. Reportamos la topografía pre y posquirúrgica. Resultado: El paciente contaba con astigmatismo preoperatorio de 15 dioptrías (D) queratométricas. El astigmatismo posquirúrgico después de la resección en cuña corneal fue de 1.7 D queratométricas, con reducción de 13.3 D queratométricas. Conclusiones: La resección en cuña es una opción efectiva para tratamiento de astigmatismos residuales altos posqueratoplastia penetrante cuando no es candidato a otros procedimientos conservadores.
There is no consensus as to the exact time at which a capsulotomy should be done. Timing of the procedure requires evaluation as a whole and consideration of the potential complications of IOL dislocation, recurrent uveitis, ocular hypertension and the most devastating choroidal effusion and retinal detachment.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
