Surgical management of astigmatism with toric intraocular lenses

摘要: Correction of corneal astigmatism is a key element cataract surgery, since post-surgical residual can compromise the patient's uncorrected visual acuity. Toric intraocular lenses (IOLs) compensate for at time correcting ocular astigmatism. They are predictable treatment. However, accurate measurement mandatory choosing correct toric IOL power and planning optimal alignment. When calculating IOLs, it important to consider anterior posterior astigmatism, along with surgically induced Accurate lens alignment calculated meridian also crucial achieve effective correction. There several techniques guide alignment, including traditional manual marking technique automated systems based on anatomic topographic landmarks. The aim this review provide an overview management relevant patient selection criteria, measurement, calculation, clinical outcomes complications.
