摘要:
The present invention provides a woven textile projection display screen including a projection display region wherein the projection display region has two or more interwoven yarns and each yarn in the projection display region includes metal. The projection display region is optically transparent in use. The invention further includes a projection apparatus including the woven textile projection display screen and one or more projectors.
摘要:
A method for calculating the required cylindrical power of a toric implant by using both the measured pre-operative corneal/ocular astigmatism and the predicted surgically-induced astigmatism. The post-operative corneal/ocular astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required spherocylindrical refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.
