Overall Length: 115.40mm. The OZ Diameter Of 9.0mm Avoids The Limbal Vessels Which Are Routinely Cut With a 10.0-10.5mm Marker. The Astigmatic Effect Is Achieved With Shorter Incisions Than Required With Limbal Incisions. Because The Diameter Is Consistent At 9.0mm, Not At The Variable Limbus Diameters, And All Incisions Are Regularly Placed In Cornea, Not The Vascular Limbus, The Results Are More Consistent. Rotate The Handle Of The Instrument To Bring The Marking Side Down To The Cornea.
