Workflow framing: PrecisionIOL should help a surgeon document the toric plan, not merely output a cylinder and axis.
The toric workflow
- Confirm corneal cylinder: compare keratometry, topography/tomography, magnitude, and meridian agreement.
- Assess posterior cornea: document whether posterior corneal astigmatism is measured, estimated, or externally verified.
- Set surgeon SIA: use surgeon-specific defaults when available and avoid generic assumptions when outcomes suggest otherwise.
- Review axis confidence: flag low-confidence axis agreement, irregular cornea, unstable tear film, or device disagreement.
- Estimate residual cylinder: compare available toric options and residual astigmatism, then show rotation sensitivity.
- Document the surgical plan: intended incision, alignment axis, backup lens thinking, and warnings.
What PrecisionIOL can add
Axis confidence
Show whether the axis is high, moderate, or low confidence based on device agreement and corneal regularity.
Posterior cornea assumption
Make the assumption visible so the surgeon knows whether it was measured or estimated.
Rotation sensitivity
Show how degrees of rotation can affect effective cylinder correction and residual astigmatism.
Documentation
Produce a surgical planning note for axis, SIA, lens option, residual cylinder, and patient counseling.
Competing against "toric calculator" searches
The page should rank for toric calculator intent while explaining that PrecisionIOL is broader than a calculator. The product helps the clinician move from measurement to confidence to plan to documentation.
