The T-Cone Toric platform complements Lenstar’s comprehensive measurement spectrum with true 11-ring Placido topography for reassurance of axis location and checking the regularity and symmetry of the astigmatism. Excellent toric IOL calculation is achieved with the integrated Barrett Toric Calculator, taking the front and back corneal surface into account. Surgical planning sketches based on high resolution images taken with Lenstar enable intuitive transfer of the plan to surgery for improved outcomes.
FEATURES
- Better accuracy for toric IOL planning – The Barrett Toric Calculator is based on the well-established Universal II formula. It considers the front and back-surface of the cornea, features dynamic lens position calculation and incorporates lens geometry details founded on thick lens calculation methodology.
- Leading technology in toric IOL prediction – In addition to axial length and Ks, Barrett’s Toric Calculator uses measured ACD, lens thickness (LT) and White-to-White to improve the prediction accuracy of the lens position. It also incorporates the posterior cornea to further increase the accuracy; peer-reviewed literature showed its superiority as compared to other methods.
- Match the axis with the T-Cone – With the optional T-Cone toric platform, the keratometry measurement of Lenstar is extended with true 11-ring Placido topography. This additional data improves the efficacy and safety of toric IOL surgery, enabling the surgeon to check the symmetry and regularity of the astigmatism.
- Have the full information, no surprises – Keratometry provides precise measurements of astigmatism and axis, but cannot detect irregularities and asymmetry. T-Cone topography provides the missing information and enables the surgeon to decide on the suitability of a particular patient to be a toric candidate.
- Visualize your plan – EyeSuite Toric Planner is part of the T-Cone Toric Platform and enables the user to intuitively plan his surgery on high resolution eye images. It also features an incision optimisation tool to minimise the residual astigmatism by placing the incision in the right spot.
- Intuitive transfer to surgery – Planning of the operation on high-resolution eye images allows the user to define additional guiding lines to anatomical landmarks recognizable in the intra-operative view. They may either serve as a baseline point for the intra-operative orientation or as a fallback strategy. The planning sketch can easily be printed and hung near the microscope.
