1. What is Eyehance Toric?

Eyehance Toric is a specialized intraocular lens designed to correct astigmatism during cataract surgery. It provides enhanced intermediate vision while maintaining good distance and near vision.

2. How Does the Calculator Work?

The calculator uses the manufacturer's proprietary formula:

The calculation takes into account:

• Corneal curvature measurements
• Axial length of the eye
• Desired postoperative refraction
• Lens position factors

3. Importance of Accurate Calculation

Details: Precise calculation is essential for optimal visual outcomes after cataract surgery with toric IOL implantation. Even small errors can significantly impact postoperative astigmatism correction.

4. Using the Calculator

Tips: Enter all required measurements accurately. Ensure proper calibration of measurement devices and consider surgeon-specific factors that may affect outcomes.

5. Frequently Asked Questions (FAQ)

Q1: What makes Eyehance Toric different from standard toric IOLs?
A: Eyehance Toric provides an extended range of vision with better intermediate visual acuity while still correcting astigmatism.

Q2: How accurate is the calculation?
A: When proper measurements are taken and entered correctly, the calculation is highly accurate, though individual results may vary.

Q3: What factors affect the calculation most?
A: Corneal topography, axial length measurement, and effective lens position prediction are the most critical factors.

Q4: Can this calculator be used for other toric IOLs?
A: No, this calculator is specifically designed for the Eyehance Toric lens using the manufacturer's proprietary formula.

Q5: How often should calculations be verified?
A: Regular verification against surgical outcomes is recommended, and formulas should be updated as new versions become available.
