IOL 3D optics studio
A paraxial ray schematic of axial length, object distance and IOL design. Education only — not a clinical power calculator, and cannot replace a registered doctor. 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.
Educational schematic only. Not an IOL prescription calculator, visual-acuity prediction, or substitute for a registered doctor’s assessment. 不能代替註冊醫生.
On a small phone screen, one finger scrolls the page; two fingers rotate the model. Landscape or a wider browser can help. Controls stay below the viewer.
Educational illustration · No patient data is collected. 不能代替註冊醫生.
Illustration cannot replace dilated fundus exam, biometry or surgical planning. A normal tool result cannot rule out disease. Not a post-operative guarantee. This site does not book or refer.
