Abstract:
The American Association of Cataract Surgeons issued the Consensus on Astigmatism Management in Cataract Surgery in 2019. To help Chinese ophthalmologists better comprehend the consensus, the main contents are explained: Toric intraocular lens(Toric IOL)implantation is the first choice for correcting corneal astigmatism. Three or more than three instruments should be used for preoperative measurement, and the values that are consistent with results should be taken. Then the Barrett Toric calculator can be used to calculate Toric IOL. When calculating toric IOL,the position of the surgical incision, surgically induced astigmatism(SIA), etc. should be considered. Then, the Toric IOL that makes resultant astigmatism close to 0 without flipping the astigmatism axis can be selected. The intraoperative automated image-guided systems can be used to guide the implantation. If residual astigmatism causes discomfort, laser in situ keratomileusis(LASIK)or IOL replacement can be used for correction. Toric IOL implantation is not recommended for patients with pseudoexfoliation(PXF)syndrome or macular lesions. There are many contraindications in dysfunctional lens syndrome(DLS)patients, which should be carried out by senior doctors. In the future, it is necessary to explore further the influence of haptic design and optic material on the rotational stability of IOL. Cataract surgery assisted by intraoperative aberrometers, automated image-guided systems or femtosecond laser still needs further development.
