With Flange - PART #VQFL
With a 144° field of view, this lens enables wide field visualization up to the peripheral retina for diagnosis and treatment of peripheral retinal defects. This lens is specially designed to provide wide field visualization even through small pupils. This application is critical when evaluating and treating patients such as those at risk of angle closure, neovascularization of the iris etc. in whom dilation should be avoided. The small pupil capability is also advantageous when treating geriatric populations in whom pupil response to dilation is limited. The large flange on this lens provides the perfect stability and control over the eye needed during laser procedures
- Wide-field distortion free viewing of the retina
- Small-pupil capability
- Ideal for detecting and treating mid to peripheral retinal abnormalities
