Peli prisms are Fresnel prisms for visual field expansion in homonymous hemianopia. They can be dispensed as temporary (press-on) or permanent prisms. In this case series, we discuss the general fitting techniques and report fitting Peli prisms in four unusual scenarios. We show that children and one-eyed patients can be fit with Peli prism. Peli prism can be fit over safety goggles, but fitting in progressive addition lenses can be challenging. Careful counseling, setting realistic goals, giving a proper Peli prism trial, orienting for spatial mislocalization, and demonstrating the visual field expansion are all key ingredients to achieve success.
