BMN/S035: Reading the Anterior Segment on a 3X Half Eye Model

Short answer: BMN/S035 is a half eyeball cut in the midsagittal plane, enlarged three times, dissecting into five parts and measuring 12 x 12 x 12 cm in PVC. The cornea, iris, lens and vitreous can be removed and refitted, the scleral muscles are attached, and part of the choroid is visible. The page publishes no price, so it is a quotation item.

Key takeaways

• A half eye, not a whole one. The midsagittal cut is what makes the anterior chamber teachable in one view.
• Four removable elements — cornea, iris, lens and vitreous — can be handed round separately.
• 3X enlargement at 12 cm keeps it desk-sized while making the iris and lens large enough to point at.
• PVC means it wipes clean and survives a classroom.
• Anatomy teaching is shifting toward embodied methods, and a model that can be dismantled fits that shift [1][2][3].

What each removable part is for

Part	Published behaviour	Teaching use
Cornea	Freely removable and refittable	Show the transparent front surface and its continuity with the sclera.
Iris	Freely removable and refittable	Explain pupil aperture and the colour ring without a diagram.
Lens	Freely removable and refittable	Hold the lens in the hand; discuss accommodation and cataract.
Vitreous	Freely removable and refittable	Fill the posterior chamber to show what sits behind the lens.
Half globe with sclera	Scleral muscles attached; part of the choroid observable	Trace an extraocular muscle to its insertion and show the vascular coat.

Why the midsagittal cut earns its place

A whole eyeball shows surface. A midsagittal half shows the axis: cornea, anterior chamber, iris, lens, vitreous, retina, and the optic nerve leaving the globe. That axis is the sequence a student has to be able to draw from memory, and it is the sequence a half model can be rebuilt into.

Recent ophthalmology education work keeps returning to the same problem — the anterior segment is easy to name and hard to picture. A 2026 paper in Frontiers in Medicine described a "hand as foot" embodied teaching method for ocular anatomy, using the learner's own hand as the model [1]. A simulation-based quality improvement study in Cureus addressed orbital compartment syndrome management, where anatomy and urgency collide [2]. A systematic review in Seminars in Ophthalmology examined the role of artificial intelligence in teaching ophthalmology skills [3]. None of them replaces a physical model; each assumes the learner has a spatial reference to reason from.

Three drills that use the five parts

1. Rebuild the axis (5 min). Remove all four elements, shuffle them, and have the student reinsert them in the correct order without a diagram.
2. Name the chamber (3 min). With the iris and lens out, ask which chamber is in front of the lens and which is behind it, and what fills each.
3. Follow the muscle (5 min). Trace one scleral muscle from origin to insertion, then explain what happens to the globe when it contracts.

FAQ

Q1. What is BMN/S035?
A half eye model, three times enlarged, dissecting into five parts, cut in the midsagittal plane and made of PVC.

Q2. How large is it?
12 x 12 x 12 cm.

Q3. Which parts come out?
The cornea, iris, lens and vitreous can be freely disassembled and reassembled; the scleral muscles are attached and part of the choroid is visible.

Q4. Is it a whole eyeball?
No. It is a half eyeball showing the detailed internal structure of one hemisphere in section.

Q5. Is a price published?
No. The page carries no price; ask for a quotation with your quantity.

Q6. How do I order?
Email chinoncpr@adaanatomy.com with model BMN/S035, quantity and delivery city.
