Keratoconus: Wavefront Correction on a Scleral Lens Using an Excimer Laser While Lens is on the Eye

https://www.gofundme.com/f/keratocunu... Keratoconus: Wavefront Non-rotational Scleral Lenses using and Excimer Laser for the integration process. This type of scleral lens would be used on a person who cannot have refractive laser surgery on their eyes. As well glasses/spectacles do not correct their vision because of the irregular shape of their cornea. Scleral lenses would be their only option to correct their vision but because of "Lens Decentration" (the lens sitting off center on their eye's sclera) their vision would still not be that good. This video explains my plan to use an Excimer Laser to integrate a patient's Wavefront (Total Zernike coefficient surface - which will cancel out the refraction in the patient's eye) into the surface of a non-rotational Scleral Lens while it is stabilized on the patient's eye. By doing this procedure while the Scleral Lens is stabilized on the patient's eye it will eliminate the need to calculate "Lens Decentration" position offsets which would be required to align the Wavefront onto the Scleral Lens if it were performed off of the patient's eye. Eg. When a CNC Lathe is used to integrate a patient's Wavefront into a Scleral Lens off of the eye; position offsets are required to align the Wavefront on the Scleral Lens so the "Optical Center" of the Scleral Lens will align with the "Optical Center" of the eye. The calculation of these lens position offsets are very complex and may not be a high enough resolution or accuracy to align the optics and remove enough refraction errors. This procedure would be very similar to performing laser ablation refraction surgery on a human cornea.
