To present the use of radiofrequency diathermy for the management of chronic resistant corneal neovascularization with lipid keratopathy.
Two post keratitis patients with chronic corneal neovascularization and lipid keratopathy refractory to conventional treatment underwent radiofrequency diathermy. (Klöti, Oertli ®, Switzerland) on an outpatient basis under topical anesthesia at the slit lamp biomicroscope.
No intra- or postoperative complications were encountered. After the procedure, significant regression of neovascularization with decrease in lipid deposition and improvement in corneal opacification was observed in both patients during the 12-month follow-up. Corrected distance visual acuity improved from 20/200 preoperatively to 20/80 postoperatively in the first case while remained stable at 20/20 in the second case. Significant symptomatic improvement regarding photophobia and discomfort was noted in both patients.
Radiofrequency diathermy seems to represent an effective and safe minimally invasive treatment for chronic resistant corneal neovascularization with lipid keratopathy.
