Dual Cross Cylinder Lenses

A Dual Cross Cylinder (split prism) allows the patient to simultaneously view the plus and minus cross cylinder lens, eliminating the need to remember which is better, 1 or 2. The exam is easier and less confusing for the patients and more precise – with 1 degree access refinements. When integrated with the Ezer ERK 9000 auto refractor/keratometer very little refinement is required for most patients.
