Description

Technical Field

[0001] The embodiment of the utility model relates to a calibration platform device, in particular to a calibration platform device for a non-contact wide-angle lens. Background Art

[0002] In ophthalmic surgeries, especially those involving the posterior segment of the eye such as vitrectomy and retinal surgery, doctors often need to use wide-angle lenses to obtain a clear and wide field of view. Traditional contact wide-angle lenses need to directly contact the surface of the eyeball, which may not only increase the risk of infection, but also cause physical pressure on the eyeball. To solve these problems, non-contact wide-angle lenses came into being, which can provide high-quality wide-angle vision without contacting the eyeball. However, precise calibration of non-contact wide-angle lenses is crucial to ensure a clear and stable field of view during surgery.

[0003] Currently, the calibration of non-contact wide-angle lenses mainly relies on manual adjustment, which is a complex and time-consuming process and requires high operator experience. This not only increases the time it takes to ship a product, but can also lead to inconsistent calibration accuracy, thus affecting the safety and effectiveness of surgery. Utility Model Content
