The YZ11D Rechargeable Direct Ophthalmoscope is a professional handheld ophthalmic diagnostic instrument designed for examination of internal eye structures, including the retina, optic disc and retinal blood vessels.
Also known as the YZ-11D Ophthalmoscope, Rechargeable Direct Ophthalmoscope, Portable Fundus Examination Ophthalmoscope or Handheld Ophthalmic Diagnostic Instrument, it is suitable for eye clinics, hospitals, ophthalmology departments, optometry practices and medical training institutions.
The YZ11D uses a 3.5 V / 2.8 W halogen illumination system that provides bright, adjustable light for direct examination of the fundus. Its optical design enables clinicians to observe visible internal eye structures during routine and targeted examinations.
The instrument features a selection of illumination options, including a large spot, small spot, slit, central grid and red-free illumination. These settings allow the examiner to select a suitable viewing pattern according to the examination requirements.
The YZ11D also offers a range of focusing lenses, with diopter compensation extending from −35 D to +20 D, enabling adjustment for differences in refractive status between the examiner and patient.
One of its key advantages is the rechargeable lithium battery system. The instrument operates from a 3.7 V rechargeable battery pack, reducing reliance on disposable batteries during regular clinical use.
The rechargeable design makes the ophthalmoscope convenient for routine consultation-room examinations, ward rounds and appropriately equipped mobile eye-care services.
The YZ11D is designed for direct ophthalmoscopy, which provides a magnified but relatively narrow view of the ocular fundus. It is an examination instrument rather than a retinal camera or optical coherence tomography system.
The ophthalmoscope is suitable for use by qualified healthcare practitioners trained in direct fundus examination.
Direct fundus examination: Supports visualization of retinal and optic disc structures.
Rechargeable lithium battery: 3.7 V battery-powered operation.
Halogen illumination: 3.5 V / 2.8 W light source.
Adjustable illumination: Allows the clinician to control light intensity.
Multiple aperture settings: Large spot, small spot, slit and central grid.
Red-free illumination: Supports assessment of selected retinal details.
Wide focusing range: Diopter compensation from −35 D to +20 D.
Portable handheld design: Convenient for clinical examinations.
Improved optical path: Designed to provide clear fundus visualization.
Dedicated charging system: Supports convenient battery recharging.
Battery protection features: Commercial YZ11D specifications describe overcharge and discharge protection.
Ergonomic examination handle: Supports controlled handheld use.
Professional clinical application: Suitable for trained eye-care practitioners.
The YZ11D Ophthalmoscope price in Kenya depends on the supplied brand, equipment configuration, battery system, charging accessories, warranty and availability.
Factors affecting the price include the exact YZ11D model, rechargeable handle and charger, included carrying case, replacement lamp availability, and after-sales support.
For procurement, confirm the complete package rather than comparing the ophthalmoscope head alone with a full rechargeable examination set.
