摘要:
Embodiments of a collagen-based ophthalmic interface for reducing patient eye movement are disclosed. In one embodiment, an ophthalmic interface serving as a partial barrier between a patients eye and a surgical laser system includes an annular-shaped collagen-based shield configured to overlay the anterior surface of the eye. The shield is applied directly to the eye with an eyelid speculum, and reduces eye movement by adding friction to the surface of the eye. In another embodiment, a collagen-based material coats an attachment ring of a conical interface for coupling a patients eye to a surgical laser system. The collagen-based coat glues the surface of the eye to the conical interface, reducing eye movement, and simultaneously eliminating the need for vacuum suction to hold the device in place. The gap in the middle of the annular-shaped collagen-coated attachment ring is filled with a liquid whose refractive index matches that of the cornea.
