Abstract: A macular sparing control method and control system for an ophthalmic laser treatment device. The method comprises: during fundus treatment by using a laser treatment device, automatically controlling a switch of the laser treatment device by using a control system; when a laser spot irradiates onto a macular area, stopping excitation of the laser treatment device; and when the laser spot leaves the macular area, starting excitation of the laser treatment device. Damages to macula lutea can be effectively avoided by designing a macular sparing system for laser treatment and another field. During a surgical operation, a surgeon can focus on treatment of an affected part without considering the problem of safety, operation can be performed more efficiently and boldly, and accordingly, the operation efficiency is increased, more comprehensive treatment is realized, and pain of a patient can be relieved to a maximum extent.

Abstract: A thermoplastic film formed of a monolithic polymer and which is embossed. The film has an embossed height of h, a material thickness of t1 at the apex of the embossed height h, and a material thickness of t2 at the base of the film. The film also has a concave cavity below the apex of the embossed height h. The monolithic polymer film is formed using a screen with a perforated pattern. A monolithic polymer is extruded onto the screen in semi-molten film. The screen is rotated such that the film passes over a vacuum slot behind the screen. A vacuum in the vacuum slot pulls the monolithic polymer into the perforated pattern of the screen without perforating the film. The perforated pattern of the screen is transferred to the monolithic polymer film as the film passes over the vacuum slot.
