摘要:
A viewing device usable by a surgeon to make an accurate corneal mark during an eye surgery procedure may be a face or head-mounted device to free the surgeons hands. The device incorporates a light producing apparatus, such as an LED, that may be positioned to be coaxial or otherwise substantially co-aligned with a line-of-sight of the surgeons dominant eye, and thus match the patients line of sight with the surgeons line of sight. The device include polarizing filters that cooperate with the light to minimize or even eliminate parallax viewing of a corneal light reflex by the surgeons non-dominant or other eye. Further, the device may also include magnification lenses to enhance the view of the eye as seen by the surgeon.
