The Power of Precise Control1-3
Experience consistent visualization that supports controlled, confident surgery across cataract, cornea, retina, and MIGS procedures.1-3
Expansive Red Reflex
Expansive red reflex geometry with an area over 2000 mm2 minimizes the need to chase the eye,
maintaining continuous visualization during surgery.1
Expanded Depth of Field
Delivers a depth of field of approximately 3,200 microns at 7x magnification.† Average human anterior chamber depth is approximately 3 mm.2,5
Longer Maximum Illumination Exposure Time
Provides 4.6x longer maximum illumination exposure time vs. focused beam illumination.6,7‡
Advanced Mode for Posterior (AMP)
Delivers up to 42% more light to the surgeon without increasing illumination in the patient’s eye.8,9
Alcon’s UNITY® M is an ophthalmic surgical microscope built exclusively for ophthalmology.4
Precision
Experience a stable red reflex and a deep depth of field
UNITY® M positions the objective lens above the illumination module which produces nearly collimated illumination and increases the focal length across working distances, helping deliver a stable red reflex and enhanced depth of field.1
A red reflex that stays locked in1,10,11
Enabled by Superior Lens Position, nearly collimated
illumination delivers a bright, stable red reflex zone that
is less susceptible to pupil size, microscope position, or patient eye movement.1,11-13‖
A depth of field that covers the chamber
UNITY® M delivers a depth of field of approximately 3,200 microns at 7x magnification†, supporting uninterrupted visualization of structures as the eye shifts or the chamber changes. Average human anterior chamber depth is approximately 3 mm.2,5
Control
First and Only Microscope with Color Tunable Illumination7,14,15**
Control coaxial and oblique light independently—across Kelvin temperature and, for the first time, color spectrum.7,14,15
UNITY® M’s first and only Color Tunable LED Illumination delivers improved contrast and tissue detail, helping surgeons distinguish critical structures across ophthalmic procedures.2,7,14-16**†† Up to 16 different preset colors are available to choose from, with the flexibility to further customize illumination to your preference.
Longer Maximum Exposure Times
UNITY® M provides high-definition visualization at low light settings, reducing patient exposure to bright light during surgery. Longer safe exposure time helps minimize the risk of phototoxicity.6,7,10,17‡
UNITY® M has 4.6x longer maximum illumination exposure time vs. focused beam illumination.6,7‡
Light Sentry Mode
Minimize the risk of photochemical retinal damage during surgery.4
When Light Sentry mode is enabled, the maximum permitted illumination level is limited to 30% of the 100% output available.4
Extends maximum illumination exposure time to >100 minutes.4‡‡
Advanced Mode for Posterior
Deliver up to 42% more light to the surgeon without increasing illumination in the patient's eye.8,9
AMP removes the internal beam splitter from the optical path, enabling full transmission of light and supporting clear posterior visualization.8
Electronic Tilt for Controlled View
Adjust the optical head to a preset
or customized angle.4
Electronic tilt supports ergonomic comfort and ease of use during MIGS and other ophthalmic procedures.4

UNITY® M: Frequently Asked Questions
UNITY® M is Alcon’s next-generation ophthalmic surgical microscope platform, designed to provide ophthalmic surgeons with precise control through advanced visualization technologies, customizable illumination, and a platform designed to evolve with future innovations.1,4,7,16
UNITY® M combines Color Tunable Illumination, Superior Lens Position, and advanced optical performance to deliver a stable visual experience and greater control throughout ophthalmic surgery.1,2,16‖‖
Color Tunable Illumination is an Alcon technology that is unique to UNITY® M which enables independent control of coaxial and oblique illumination, allowing surgeons to adjust the characteristics of the illumination to optimize contrast and visibility of ocular tissues. By providing greater control over how structures are illuminated, surgeons can tailor visualization to their preferences and the needs of the procedure.2,7,16††
Superior Lens Position is a proprietary Alcon optical design that positions the objective lens above the illumination module. This helps deliver a bright, stable red reflex and enhanced depth of field, supporting consistent visualization throughout surgery.1‖‖
UNITY® M combines Superior Lens Position technology with advanced illumination design to help maintain a bright, stable red reflex throughout surgery.1,16‖‖ Enhanced depth of field helps keep structures in focus across changing surgical conditions,2‖ while the expansive red reflex is designed to be less susceptible to changes in eye movement, microscope position, and pupil size.1,11-13‖ Color Tunable Illumination helps you see what matters; Superior Lens Position helps you keep it in view.
