Management of Cataract in Patients with Irregular Astigmatism with Regular Central Component by Phacoemulsification Combined with Toric Intraocular Lens Implantation

Table 3

Preoperative corneal astigmatism and postoperative residual astigmatism.

	Preoperative corneal astigmatism				Residual
	IOL Master	Keratometer	Corneal topography	Average
Astigmatism	2.24 ± 1.25	1.84 ± 1.23	1.89 ± 1.44	1.99 ± 1.26	0.65 ± 0.57
	1.2 – 6.5	1 – 6.75	1 – 7.66	1.15 – 6.97	0 – 2.75

The data are expressed as the mean ± standard deviation (range). ; vs. the preoperative value. The average represents average corneal astigmatism (the average of IOL Master, corneal topography, and keratometer values).The residual represents postoperative refractive astigmatism.
