IOL 3D optics studio

Explore how light, eye length, and lens design interact.

On a small phone screen, landscape or a wider browser works better for the 3D model. Controls stay below the viewer.

Educational schematic only. Not an IOL prescription calculator, visual-acuity prediction, or substitute for an ophthalmologist’s assessment.

⚠ 此模型數字只作光學教學示意,並非確定的臨床結果,亦不可用作人工晶體度數或散光軸位選擇;實際結果須由主診醫生按檢查及量度決定。

These numbers come from a simplified optical teaching model. They are not a definite clinical outcome, not a prescription, and must not be used to choose an IOL power or astigmatism axis; actual results and lens choice depend on your treating doctor’s examination and measurements.

このモデルの数値は光学教育用に簡略化した図示であり、確定した臨床結果ではありません。処方ではなく、眼内レンズ度数や乱視軸の選択に使うことはできません。実際の結果とレンズの選択は、主治医の検査と測定によって決まります。

Object distance ∞ from corneal plane
Distance-branch principal foci — mm relative to retina; − = in front
Schematic retinal RMS radius — µm; includes all modeled branches

Retinal light footprint

Ray-intersection diagram, not a simulated photograph, point-spread function, or predicted patient vision.

Teaching scenarios

Presets isolate teaching concepts. They are not treatment recommendations.
