Embodiment Construction

[0028] The present disclosure relates to systems and methods for marking on the cornea of ​​an eye using markers. Even when the cornea is already deformed at that time, the markers allow later detection of selected locations on the cornea, such as the center of the pupil or the apex of the cornea at a given dilation. The present disclosure also relates to systems and methods for performing vision correction surgery using markers. The cornea is deformed during such surgery, but despite the deformation, the markers allow surgery to be performed at selected locations, often improving vision correction once the cornea returns to its undeformed shape. The markers also allow the selected location to be the center of the pupil or the apex of the cornea at a given dilation. Performing surgery at the apex of the cornea as opposed to the center of the pupil or at the center of one dilated pupil as opposed to the other can provide different vision corrections.

Abstract

The present disclosure relates to systems and methods for marking an undeformed cornea with markers to allow later detection of selected locations on the cornea after deformation, and to systems and methods for performing vision correction surgery based on the markers. Systems and methods for surgery.

Description

technical field [0001] The present disclosure relates to systems and methods for performing vision correction surgery. Background technique [0002] A number of different vision corrective surgeries are currently available to improve a patient's vision. These surgeries include laser-assisted corneal ablation surgery, which alters the refractive properties of the cornea to correct defects in the lens within the eye. One common such surgical procedure is known as LASIK (Laser Assisted In Situ Keratomileusis) and is used to correct myopia, astigmatism, or more complex refractive errors. These surgeries also include lens removal surgery, which uses a different method to alter the refractive properties of the cornea to correct defects in the lens within the eye. One common such surgical procedure is known as SMILE (Small Incision Lens Extraction) and can be used to correct many refractive errors that can also be corrected by LASIK (eg, myopia). Other surgical procedures can co...
