9. Allows better visualization during endophotocoagulation by allowing a complete view of the fundus and the area of the scleral buckle. Endophotocoagulation can be applied more completely and precisely.
10. Allows improved visualization during peripheral retinotomies for the release of traction or retinal incarceration, or for the retinotomies required to extract subretinal membranes.
11. A stereo image inverter with maximal light transmission was developed using a uniblock prism cluster consisting of an Abbe modification of the Porro prism. The prism cluster can be perfectly adjusted to any surgical microscope eliminationg diplopia (double vision). No other system has this unique capability.
