ABSTRACT
PURPOSE: To report a case of epithelial downgrowth after penetrating keratoplasty. CASE DESCRIPTION: A 58-year-old man presented with graft rejection in his three-month-old, repeat penetrating keratoplasty. Examination revealed centripetal opacification of the posterior cornea due to deep epithelization. He had new retro-corneal membranes and anterior uveitis. Specular microscopy and anterior segment optical coherence tomography were performed, and a clinical diagnosis of epithelial downgrowth was made. The patient had intracameral injections with 5-fluorouracil (5FU) and achieved resolution of intraocular findings after treatment. CONCLUSIONS: Epithelial downgrowth is an uncommon complication of penetrating keratoplasty. It affects the patients' visual acuity and graft survival. Clinical observation is preferred in severe cases due to the high risk of intraocular damage; intracameral 5FU promises to be a good option in these cases.

Objetivo : determinar la Eficacia de la Queratectomìa Subepitelial Asistida por Laser en miopía leve a moderada. Metodología : estudio retrospectivo de corte transversal con revisión de Historia Clìnicas del Instituto de Còrnea Bogotà D.C.,en 71 pacientes encontrados con miopía sin astigmatismo a quienes se les realizò Lasek entre Enero 2000 y Junio 2004. Para verificar la Eficacia del procedimiento de relacionò agudeza visual sin correcciòn y equivalente esfèrico preoperatorios con los postoperatorios a un mes.Resultados : Casos con agudeza visual 20/40 ò mejor 97 por ciento y con 20/20 72 ciento.Refracciòn entre màs ò menos 1.0 D. 100 ciento. Refracciòn entre màs ò menos 0.5 D. 69 ciento. Equivalente Esfèrico preoperatorio -2.95 D.con resultado al mes de +0.02 D. Conclusiones : Lasek se considera una cirugía refractiva eficaz para la correcciòn de la miopía leve a moderada.
The purpose was to determine the Efficiency ofthe Sub Epithelial Keratectomy Aided by Laser inlight to moderate myopia. Methods: a retrospectivetransversal study was done by checking the clinicalrecords at the Institute of Cornea in Bogotá of 71patients with myopia without astigmatism to whomLasek was practiced between January 2000 andJune 2004. In order to verify the Efficiency of theprocedure, the visual acuity without correction andpreoperative spherical equivalent were related to thepostoperative result a month later. Results: there werecases with visual acuity of 20/40 even or better 97 percentand with 20/20 72 percent. There was refraction betweenapproximately 1.0 D in the 100 percent of cases There wasrefraction between more or less 0.5 D in the 69 percent.Preoperative spherical equivalent was -2.95D, with aresult a month later of +0.02 D. Conclusions: Lasekis considered an efficient refractive surgery to correctlight to moderate myopia.
