Abstract

Purpose:

To present the use of radiofrequency diathermy for the management of chronic resistant corneal neovascularization with lipid keratopathy.

Methods:

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.

Results:

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.

Conclusions:

Radiofrequency diathermy seems to represent an effective and safe minimally invasive treatment for chronic resistant corneal neovascularization with lipid keratopathy.
