Contact Lens Vertex Calculator 頂點距離計算機

 

Toric Contact Lens Vertex Calculator (Astigmatism)

OD Sphere (D)

OD Cylinder (D) (minus)

OD Axis (°)

Vertex distance (mm)

OS Sphere (D)

OS Cylinder (D) (minus)

OS Axis (°)

Round to (D) 0.25 0.50

Expected rotation (°)

Rotation direction None Clockwise (Right) — subtract axis Counterclockwise (Left) — add axis

Use rotation compensation (LARS) only if you consistently observe rotation on-eye.

Educational tool only. Final lens selection, axis availability, and fit must be verified with trial lenses and clinical judgment.本工具僅供教學參考。最終鏡片選擇、軸位選擇和適配情況必須透過試戴鏡片和臨床判斷進行驗證。
