funduslinse

Funduslinse is a specialized type of lens used in ophthalmology for examining the posterior segment of the eye, known as the fundus. It is an aspheric, multi-element lens that attaches to an ophthalmoscope or slit lamp to provide a magnified, real, and inverted image of the retina, optic disc, macula, and blood vessels. These lenses are designed to correct for aberrations introduced by the eye's own optics, offering a clearer and wider field of view than direct ophthalmoscopy. Different types of fundus lenses exist, varying in magnification power and field of view, allowing ophthalmologists to diagnose and monitor a wide range of conditions such as diabetic retinopathy, glaucoma, macular degeneration, and retinal detachments. The lens is typically held close to the patient's eye, and illumination is directed through it to visualize the internal structures.
