Digital 3-D Visualization and Guidance in Cataract Surgery
Narrative Responses:
Purpose
To evaluate the accuracy of toric IOL prediction and alignment using the TrueVision Refractive Cataract Toolset surgical guidance applications integrated with the Cassini corneal topography (i-Optics).
Methods
TrueVision is a stereoscopic high-definition visualization system that displays the surgical field of view in real-time on a 3D flat-panel display in the operating room. Cassini is a corneal diagnostic device based on multi-color LED technology. Corneal astigmatism measured with the Cassini preoperatively is transferred and used by the TrueVision Toolset surgical guidance during the surgery. We will record the toric IOL alignment recommended by the TrueVision and routine marking technique. Manifest refraction and toric IOL alignment will be obtained 3-6 weeks following cataract surgery.
Results
Suggested toric IOL alignment discrepancy between the TrueVision and routine marking technique will be determined. Based on the postoperative manifest astigmatism and toric IOL alignment, the accuracy of toric IOL prediction and alignment with the combined TrueVision and Cassini device will be calculated and analyzed. In the first 2 eyes tested, capture was rapid and accurate.
Conclusion
Results from this study will demonstrate the accuracy of the toric IOL prediction and alignment using the TrueVision Refractive Cataract Toolset® surgical guidance applications.
