Treatment Options For Keratoconus

Topography-Guided Conductive Keratoplasty

Topography-guided conductive keratoplasty is for patients looking for an effective and non-invasive procedure. It makes use of radiofrequency to correct presbyopia and hyperopia with or without astigmatism. This treatment is also cost-effective, making it an important achievement in refractive surgery. Conductive keratoplasty is dependent on the impact of temperature on the cornea’s biomechanical properties. The collagen of the cornea dehydrates and retracts at a certain temperature but can maintain its original configuration upon cooling. Patients who underwent this procedure were found to have achieved 20/40 vision. Foreign body sensation and light sensitivity are the most common side effects of this surgery. Aside from these two, some patients also complained of astigmatism, which is usually caused by inaccurate cornea markings, asymmetric application of spots, and more than one insertion of the probe on the same spot.
