Optical parameters
⚠ 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。
IOL design
Monofocal
EDOF — schematic
Multifocal — schematic trifocal
Toric monofocal

Enable toric correction
Angles here are model meridians, not surgical marking instructions.
Cylinder is specified at the IOL plane.
Refit distance power
Match toric in model
Changing axial length does not automatically change IOL power.
Use “Refit distance power (teaching model)” to demonstrate recalibration.

Teaching scenarios
1. Monofocal / distance
2. Monofocal / reading
3. Uncorrected astigmatism
4. Aligned toric correction
5. Rotated toric correction
6. Longer eye / fixed IOL
7. EDOF / intermediate
8. Multifocal / near
