About Kepler

What magnification options does Kepler support?

Kepler is offered in 4.0x, 5.0x, and 6.0x — high-magnification configurations purpose-built for microsurgery, supermicrosurgery, peripheral nerve work, and fine vascular cases.

Is Kepler suitable for first-time loupe wearers?

Usually no. Kepler is a high-magnification surgical platform that demands stable working distance, good lighting, and steady technique. Most residents do better starting with Galileo, Newton, or Apollo at 3.0x–3.5x and stepping up to Kepler later.

How much does Kepler weigh?

Kepler with frame is 68–85 g depending on configuration. The build uses premium optical glass with multi-layer coatings and rigid metal barrels.

Are there discounts for residents and fellows?

Yes. Resident- and fellowship-friendly pricing is documented across the HeliosX lineup. Email heliosxloupes@gmail.com with your training program details to confirm.

Fellowship-affordable microsurgery loupes

Could not justify $4-5k as a fellow. Kepler 5.0x has done everything I have needed for replants and digit-level work. Image quality is in the same class as the high-end set my attending wears. Genuinely impressed.

Use them for free-flap planning every week

I needed something I could wear into the OR for flap inset where the microscope is overkill. Kepler 6.0x is what I picked and I have not regretted it. Sharp, well balanced, IPD was dead on out of the box.

Best price-to-resolution ratio I have found

I do hand and microsurgery reconstruction. Kepler 6.0x is comparable to my old Designs for Vision pair at less than half the price. The fit measurement process is more thorough than the big brands I have ordered from.

6.0x with a usable field is rare at this price

I do a lot of oculoplastic work that wants more than 4.5x but does not warrant a microscope setup. Kepler at 6.0x has a usable field and the contrast holds at the edges. Glad I tried it instead of buying another Designs for Vision set.

Real microsurgery option at half the usual price

I trained on a Zeiss scope and use loupes for digital nerve work. Kepler 5.0x renders epineurium clearly, comparable to my old high-end Galilean. The price difference paid for two trips to AAOS.

Crisp at 4.0x for daily lid work

I picked 4.0x for lid and lacrimal cases. Field is wide, edges are sharp, depth of field is forgiving. Replaced a 5-year-old prismatic that was due for a service anyway. Good move for the budget.

Great optics, heavier than the lighter models

No surprise that 5.0x prismatic is heavier than 2.5x Galilean. Worth it for the resolution. Drop one star only because the weight is real after a full open AAA case. Not a flaw, just physics.

Built for real operators

Designed in the OR, priced for reality.

HeliosX exists because surgeons shouldn't have to choose between compromised tools and two months of rent. The work is demanding enough-the access should be too.
