Applying wavefront sensors and corneal topography to keratoconus

Biomed Sci Instrum. 2002:38:471-6.

Abstract

We report preliminary results from a study to create custom optics (contact lenses) for persons with the eye disease Keratoconus. Custom optics are intended to correct for higher order aberrations which cannot currently be corrected with conventional contact lenses. A lens design algorithm has been developed that utilizes both wavefront sensor data and corneal topography data. The lenses will be formed from thick, pre-fabricated soft contact lenses using laser ablation. Preliminary ablation of these lenses is demonstrated using a femptosecond Ti: Sapphire (Ti:Al2O3) laser system.
