Sterling Ultra Precision, a provider of single-point diamond-turning systems for the ophthalmic industry, has introduced its Optovision 200 vision system for use on its Optoform ophthalmic lathes. Optovision 200 accurately locates and registers the toric axis on contact lenses and intraocular lenses (IOL) during the manufacturing process.
Many of the latest contact and IOL designs incorporate toric geometries for better visual acuity and improved wearer comfort. Proper orientation of the toric axis to the first or second side geometry is critical in lens prescription functionality. Sterling’s Optovision 200 vision system and Optomark marking system enable automated alignment and registration of the toric axis during the lens machining operation.
Standard contact and IOL manufacturing methods utilise a mechanical registration technique on the arbour to ensure proper toric orientation throughout the entire production process. This method is more time consuming and prone to prescription errors than using the Optovision 200 vision system.
The vision system is accurate, repeatable and accommodates various diameters, material colours and mark configurations and can be retrofitted easily to existing Optoform lathes for increased production efficiency and enhanced product quality.
