Fig. 4From: Comparison of two techniques for toric intraocular lens implantation: hydroimplantation versus ophthalmic viscosurgical devicesAstigmatism vectors. The x-axes represent the J0 power vector (D). The y-axes represent the J45 power vector (D). (OVD ophthalmic viscosurgical device, J0 Jackson cross-cylinder, axes at 0 degree and 90 degree, J45 Jackson cross-cylinder, axes at 45 degree and 135 degree)Back to article page
