Field Induced Mydriasis — the world's first device to dilate the pupil without drops, without contact, and without the wait.
Mydriasis is the medical term for pupil dilation. FIM stands for Field Induced Mydriasis — inducing this exact clinical state without drugs, drops, or contact. The visuals below show how a dilated pupil (mydriasis) compares to a normal, constricted (miosis), or unevenly sized (anisocoria) pupil.
Captured by a leading digital imaging system using proprietary ATI software for precise measurement of pupil size, under normal eye examination room conditions.
FIM is easily installed on any standard slit lamp. Its operation is seamlessly integrated with the standard ophthalmology examination procedure without pre-examination preparations or waiting periods.
The patient sits in front of the slit lamp, as in a regular procedure, placing their head within the headrest.
The doctor adjusts the slit lamp microscope for the examination, exactly as in a regular procedure.
The doctor turns FIM on and waits up to two minutes, until the pupil is fully dilated.
The OFE is adjusted to maintain ~12–15mm from the patient's eye, and the doctor proceeds with the exam.
At the end of the procedure, the doctor simply turns FIM off, or the patient can remove their head from the chin rest.
The pupil recovers to normal condition within minutes, without any side effects.
Generates the safe electromagnetic field that induces pupil dilation. Mounted on the slit lamp in front of the examined eye at ~12–15mm, with a hollow ring aligned to the slit lamp's microscope. Optional lenses can be inserted as in regular exams.
Holds the system software, LED signals and controls, generating all signals converted into electromagnetic fields at the OFE. Simple on/off switch with LED feedback lights, powered via a standard medical power adapter.

Ocular hypertension is the most important risk factor for glaucoma, but today's gold-standard tonometer can only be used by a professional. ATI is developing NIT, a personal ocular tonometer offering fully automatic IOP measurement — enabling self-examination by patients at home.
The non-invasive measurement is performed on a closed eye via the eyelid, using image processing of a reference pattern that deforms under applied pressure — making frequent, timely glaucoma screening accessible outside the clinic.
We're happy to walk you through a live demo, share clinical data, or talk through what it takes to get FIM installed at your practice.
