Know Our Ophthalmic Equipment: 20D, 78D & 90D Lenses

At Focus Eye Clinic, Thane, we use specialised diagnostic lenses like the 20D, 78D, and 90D to perform detailed examinations of the inside of your eye. These lenses help Dr Mohini Modak assess the retina, optic nerve, and macula with exceptional clarity.

The 20D lens is commonly used with an indirect ophthalmoscope to obtain a wide view of the retina, making it invaluable for detecting retinal tears, detachments, and diabetic retinal disease. The 78D and 90D lenses are used with the slit lamp microscope to provide a magnified view of the optic nerve and central retina, aiding in the diagnosis and monitoring of glaucoma, macular disorders, and diabetic retinopathy.

These advanced lenses enable early detection of sight-threatening conditions, often before symptoms appear. At Focus Eye Clinic, we combine modern technology with expert clinical care to help protect your vision and maintain lifelong eye health.
