The Cataract Pre-OP Display was developed to aid in premium IOL selection. It consists of four easy steps to help the surgeon determine if a specific eye is suitable for premium IOLs. The four steps are:
Step 1: Evaluation of corneal irregular astigmatism and chord distance (Is a cornea suitable for MF IOL)
Step 2: Detection of abnormal corneal shape (Aids in formula choice)
Step 3: Evaluation of corneal spherical aberration (Is a cornea suitable for aspheric IOL)
Step 4: Evaluation of corneal cylinder (Compare anterior astigmatism to total astigmatism)
