SEATTLE — Conductive keratoplasty may be a viable option to treat keratoconus, said Helen Wu, MD.
She presented results during the ASCRS Summer Refractive Congress from a case study on a 40-year-old man who had mild to moderate keratoconus and underwent CK to treat it.
The patient had a significant amount of surface disease due to rosacea blepharitis that had been treated with multiple modalities by many practitioners, she explained.
The patient was also contact lens intolerant and a high myope with high astigmatism; he did not want to undergo Intacs placement or penetrating keratoplasty.
His uncorrected visual acuity was 20/200 in the right eye and 20/50 in the left eye. His best corrected visual acuity was 20/40 in the right eye and 20/25 in the left eye.
Dr. Wu used CK, placing five spots on the apex of the cone to flatten the cone based on the elevation map outside the pupillary border.
“His UCVA improved from 20/200 to 20/50 on the first postoperative day, and he later regressed back to 20/200. He was able to wear a toric soft contact lens with a BCVA of 20/30 in his right eye at 1 month postop,” she said.
“Early results with standard CK technique show regression that is significant after a year, but the LightTouch technique may afford better results and possibly could be used in combination with Intacs,” she said.
