With indirect ophthalmoscopy, the fundus is illuminated by light passing through the EDL-90D lens. The returning light then passes back through the EDL-90D to form a real, inverted image of the fundus between the lens and the practitioner.
The advantages of binocular indirect ophthalmoscopy compared to direct exams are the excellent, stereoscopic field of view and the ability to assess subtle diffuse fundus color changes.
The EDL-90D is the perfect lens for fundoscopy and is especially well suited for examining patients with small pupils. It is made of high-transmittance glass to achieve distortion-free imaging. Users will obtain bright, clear images across the entire field.
The EDL-90D features a computer optimized aspheric design that minimizes reflections and delivers high-resolution images. A small diameter holding ring also contributes to ease of use.
