发明名称 Delensing of ophthalmic lenses using gas
摘要 Contact lens delensing methods are described, and the present delensing methods include using a gas to facilitate separation of a polymerized contact lens product from a contact lens mold member. The contact lens mold member is compressed to deform a portion of the mold member, and gas, such as air, is directed toward the polymerized contact lens product in contact with the portion. The contact lens mold member can be compressed as the mold member and lens product rotate. A vacuum device can be used to separate the polymerized contact lens product from the contact lens mold member after compressing the portion of the mold member and directing the gas towards the mold member. Delensing systems used to practice the present methods are also described.
