Alden Optical recently launched Zenlens, its new mini-scleral design co-designed with Jason Jedlicka, OD, FAAO, FSLS, president of the Scleral Lens Education Society.
Zenlens offers 16 and 17 mm diameters, each available in prolate and oblate designs, and features Smart Curve, a design element that compensates for discrete parameter adjustments while preserving the remaining optimized parameter values.
Zenlens is diagnostically fit via a 24-lens set. With two diameters and two profiles, the set can be considered as four mini-sets. Fitters determine appropriate lens diameter from horizontal visible iris diameter (HVID), then design profile from the corneal shape. Smart Curve ensures that only the parameter needing refinement changes, while all others remain constant. Zenlens is produced in Boston XO and XO2 and Contamac Optimum Extra materials.
