Medusa
From $1,695Ergonomic prismatic loupes with adjustable working distance for clinicians who change posture between seated and standing work.
Working distance adjusts from 300–600 mm. Magnification does not switch on the loupe.

Cardiac Surgery Loupes
Cardiothoracic surgeons relied on loupes more than microscopes in the Jarrett 2004 survey of intraoperative magnification. Coronary anastomoses, valve repair, and bypass workflows benefit from prismatic magnification without the setup time of an operating microscope.
We make and sell HeliosX loupes. This is our buying guidance, not an independent product test or paid ranking.

Where loupes win in cardiac work
Cardiothoracic teams use loupes routinely for vessel anastomoses, valve suturing, and exposure of small structures. The portability and quick switch-in beats microscope setup for the majority of CABG and valve cases.
- Vessel anastomoses where 4.0x to 5.0x covers the working field.
- Valve repair and reconstruction where ergonomic posture matters across long cases.
- Bypass workflows where setup time and visual axis stability are at a premium.
Which HeliosX model fits cardiac workflows
Apollo and Medusa cover most cardiac and cardiothoracic work with ergonomic prismatic optics. Kepler steps in when the case needs higher magnification on small vessels or fine reconstructive detail.
- Apollo: ergonomic prismatic at 3.0x to 6.0x for general cardiac work.
- Medusa: same prismatic optics with adjustable working distance for posture-flexible cases.
- Kepler: 4.0x to 6.0x when small vessels or fine reconstructive detail drive the choice.
Fit, magnification, and ordering
A cardiac surgeon picks magnification around the most common procedure, not the rare one. HeliosX measures pupillary and working distance after checkout and builds the loupe around your posture and frame preference.
- Pick the magnification that matches your most-used case mix, not the outlier.
- Submit pupillary and working distance after checkout; production is custom.
- Frame and prescription options come in the same flow.
Questions before buying
What magnification do cardiothoracic surgeons use most?
Cardiothoracic surgeons commonly use 4.0x to 5.0x loupes for routine anastomoses and valve work, stepping up to 5.0x or 6.0x when the case is dominated by small-vessel detail.
Are loupes enough for coronary anastomoses or do I need a microscope?
For routine CABG cases, loupes at 4.0x to 5.0x are widely sufficient. Microscopes remain valuable when the anatomy or revision case demands higher magnification beyond the loupe range.
