Adjusting ophthalmic docking system
An adjusting ophthalmic docking system is described that includes a curved contact element, disposed on a procedure eye, a conformation platform at a distal tip of an optical system to support an adjustment of the curved contact element, and a connector to accommodate the adjustment of the contact element. The curved contact element can be a meniscus-shaped contact lens, with a proximal surface radius larger than a distal surface radius. The contact lens can be made of an approximately refractive index-matching material, such as a fluoro-polymer.
