Abstract: Corneal astigmatism is an important factor affecting the efficacy of refractive cataract surgery. Astigmatism correction intraocular lens (Toric IOL) implantation is the main way to correct cataract astigmatism in clinic. Different materials and shapes of Toric IOL and long eye axis of high myopia will affect the stability of IOL in the capsule bag. Refractive excimer laser surgery can accurately correct residual astigmatism after cataract surgery, but it has not been widely used in clinic because of price and secondary surgery. Cataract surgical incisions on the steep axial of the cornea to correct astigmatism does not increase the additional risk, but the correction range is limited. Arcuate keratotomy is simple and easy, combined with femtosecond laser can further improve the accuracy of correction, which has a great prospect of clinical application.(Int Rev Ophthalmol, 2022, 46: 430-436)
