"I use the MASTEL 5.75 mm corneal marker every time I use a Rezoom or Restore lens. (I offset a fraction of a millimeter inferior and nasal within the related pupil). The corneal mark is a perfect grade for the capsulorhexis and its perfect every time. The IOL is centered, the PCO rate is very low (20% in mulifocal lenses) and the patient and surgeon are "20/happy"."
