Portable & Handheld Slit Lamps
A portable slit lamp brings anterior-segment biomicroscopy to the patient instead of requiring the patient to reach a fixed exam lane. Pairing a focused, adjustable slit beam with magnified binocular viewing, a handheld unit lets you assess the lids, conjunctiva, cornea, anterior chamber, iris and lens in settings where a table-mounted instrument is impractical — bedside and long-term-care rounds, the OR and emergency department, pediatric and low-mobility patients, and off-site screening or mobile clinics.
US Ophthalmic is a US provider of portable slit lamps for practices, hospitals and mobile eye-care programs. Our own EZER brand anchors the portable line with the ESL-700 and ESH-770, and we also carry the compact Kowa SL-19 and an anterior-segment module for the MiiS portable imaging platform. Every unit is backed by a US warranty and direct support from our team, and we will help you match a model to how and where you actually examine patients.
How to choose a portable slit lamp
- Optics and magnification: Confirm the magnification steps and viewing quality match your exams. A converging binocular optical system gives the depth perception you need to judge anterior-chamber depth and corneal layers. The EZER ESL-700, for example, ships with a 10x eyepiece and accepts a 16x eyepiece when you want additional detail.
- Illumination and filters: Look for a bright, brightness-adjustable LED with a variable slit width and the filters your clinical work requires. Cobalt blue is essential for fluorescein evaluation of abrasions, ulcers and contact-lens fit; red-free (green) adds vascular detail. The ESL-700 carries three built-in illumination-pathway filters and the MiiS module includes integrated blue and green filters.
- Portability, power and ergonomics: Weight, balance and grip decide whether an instrument is still comfortable after a full morning of exams. Check the battery format and rated runtime against your rounds — the ESL-700 is rechargeable and rated at roughly 2.5 hours of use. One-handed operation matters most for pediatric, geriatric and bedside patients.
- Documentation and imaging: Some practices only need a direct-view instrument; others want to capture the anterior segment for the chart, patient education, referrals or telemedicine. If documentation matters, choose a platform built to integrate with a capture system rather than retrofitting one later — the MiiS Portable Slit Lamp is designed to add slit-lamp capability to the MiiS fundus-camera platform.
- Warranty and US support: A portable slit lamp is a long-term clinical instrument. Buying from a US provider means a US warranty and a direct line to a team that knows the product, rather than an orphaned import with no support behind it.

Frequently asked questions
What is a portable slit lamp used for? It provides magnified, focused-beam examination of the eye's anterior structures — lids, conjunctiva, cornea, anterior chamber, iris and lens — anywhere a fixed slit lamp cannot go. Typical uses include bedside and nursing-facility rounds, the OR and ER, pediatric and low-mobility patients, and mobile or off-site vision screenings. With cobalt-blue illumination and fluorescein it also supports evaluation of corneal abrasions, ulcers and contact-lens fit.
How does a portable slit lamp compare with a tabletop model? A handheld prioritizes mobility and point-of-care access. Table-mounted units generally offer a wider magnification range, greater stability and more extensive imaging options. Most practices keep a fixed slit lamp in the lane and a portable for bedside, mobile and hard-to-position patients — the two are complementary rather than interchangeable.
What magnification and illumination should I look for? For most anterior-segment work a 10x view handles general assessment and a higher-power eyepiece adds detail; the EZER ESL-700 ships at 10x and accepts a 16x eyepiece. On illumination, choose a bright, brightness-adjustable LED with a variable slit width and at minimum a cobalt-blue filter for fluorescein exams.
Can a portable slit lamp document findings or connect to imaging? It depends on the model. Direct-view handhelds such as the EZER ESL-700, the EZER ESH-770 and the Kowa SL-19 are built for live observation. The MiiS Portable Slit Lamp is designed to add anterior-segment slit-lamp capability to the MiiS fundus-camera platform when capture and documentation matter.
