Toric lens alignment without ink markers.
Skip the uncomfortable pre-op ink marking. Capture a high-quality, enhanced photo of the eye, identify conjunctival or limbal landmarks with clarity, and use them as precise references for your Mendez gauge in theatre.
Two ways to use it. Both replace the need for pre-op ink marking.
Capture a levelled photo of the eye with gyroscope guidance — no ink marks needed.
Place digital markers on conjunctival or limbal landmarks using the protractor overlay to record their axis position.
In the OR, align your Mendez gauge to the same landmarks, place your ink reference marks, then proceed with IOL implantation and rotation as usual.
Place an ink mark at any position on the limbus before or at the slit lamp.
Photograph the eye and place a digital marker on the ink mark. The app tells you exactly what axis it sits on.
Use the known axis of your ink mark as the starting reference for your Mendez gauge to align the toric IOL.
Every feature designed to be fast and precise under surgical conditions.
Precise 0–180° ophthalmic protractor overlay with major, minor, and fine tick marks. Place up to two markers and an IOL axis line.
Real-time gyroscope-guided level indicator ensures the camera is perfectly horizontal when capturing. Green means go.
Microscope-ready display with bright markers and rotated protractor. Designed for quick glances during surgery.

Instead of placing ink marks on the cornea before surgery, you photograph the eye and identify natural conjunctival or limbal landmarks. The app records the axis of each landmark using a digital protractor. In theatre, you align your Mendez gauge to those same landmarks to place your axis marks, then proceed with IOL implantation and rotation as usual.
Yes. You can place an ink mark anywhere on the limbus, then photograph the eye and use the protractor overlay to identify exactly what axis that mark sits on. This gives you a precise reference for your Mendez gauge in theatre, even if the mark wasn't placed at a standard position.
Any consistent, identifiable feature at or near the limbus works — for example, a prominent conjunctival vessel, nevus, limbal scar or any pigmented lesion. The key is that you can recognise the same landmark under the operating microscope.
Traditional methods rely on ink marks placed at the slit lamp as a reference for protractor-based alignment in theatre. Toric IOL lets you skip the ink entirely by using natural landmarks, or makes ink-based marking more precise by identifying the exact axis of any mark you place. Either way, you arrive in theatre with a known reference rather than an estimated one.
