Keeler Allpupil II LED — Used Wireless Binocular Indirect Ophthalmoscope
The Keeler All Pupil II LED Wireless binocular indirect ophthalmoscope is the wireless, LED-powered version of the All Pupil II platform, built for clinicians who do peripheral retinal examination off the slit lamp and don’t want to be tethered to a wall outlet during a long ROP round or scleral depression exam. This used keeler allpupil ii led headset ships inspected, with batteries confirmed working, and a 90-day warranty.
The headset weighs 520 g, drives a 4,000 K neutral LED at up to 2,000 lux, and dims down to 2% for sensitive patients (NICU rounds, post-op pupils, photophobic adults). The All Pupil II’s Single-Control Aperture changes both aperture size and position with one switch motion — meaningful when you’re working with a patient whose pupil dilates poorly. A built-in IR/UV barrier filters the harmful spectrum, protecting both clinician and patient over a long screening day.
Per a National Library of Medicine-indexed study (J AAPOS, 2025), binocular indirect ophthalmoscopy remains the cornerstone of retinopathy of prematurity screening — a workflow this BIO is specifically designed to support.
Why Practices Choose the All Pupil II LED
Wireless cordless operation — slimline lithium-polymer pack lives on the headset; no power cord, no spilled cable. Critical for room-to-room ROP rounds and bedside exams.- 4,000 K LED — up to 2,000 lux — bright enough for difficult media (cataract, hemorrhage) and small pupils, dimmable to 2% for patient comfort.
- Convertible technology — switch the same headset between LED module and traditional 3,800 K Xenon bulb if you prefer the warm light for color photography or training.
- Single-Control Aperture — one switch adjusts aperture size AND position together; faster than two-lever competitors when pupil sizes vary across a screening list.
- Built-in IR/UV barrier — blocks the harmful spectrum without requiring an aftermarket filter clip-on.
- 520 g headset weight — extra-padded headband makes it tolerable across an ROP round or a 30-patient screening day.
- 3D high-contrast retinal images — Keeler’s optical signature for stereo depth perception during peripheral exam.
Clinical Applications
- Retinopathy of prematurity (ROP) screening rounds in NICU
- Peripheral retinal examination with scleral depression — retinal tear, lattice, retinoschisis
- Pre-operative retinal evaluation for cataract and refractive surgery
- Post-vitrectomy peripheral assessment
- Diabetic retinopathy peripheral grading where wide-field imaging is unavailable
- Mobile retinal screening clinics where outlet power isn’t reliable
Who This Is For
- Pediatric ophthalmologists doing ROP screening rounds
- Retina specialists needing a reliable cordless BIO for inpatient consults
- General ophthalmology and optometry practices building a peripheral-retina exam workflow
- Clinics standardizing on the Keeler ecosystem (replacing aging halogen All Pupils)
