Toric IOLs in Keratoconus Patients with Cataract
2018Toric intraocular lenses (IOLs) were designed for patients with regular corneal astigmatism, usually during routine cataract surgery. Keratoconus is the classic example of irregular astigmatism and used to be considered as a contraindication for toric IOLs.

Correction of Corneal Astigmatism with Toric IOLs
2014Anterior and posterior corneal astigmatism must both be considered when calculating toric intraocular lenses (IOLs). The purpose of the two studies discussed in this chapter was to assess the relationship between anterior and posterior corneal astigmatisms and to evaluate the clinical impact of posterior corneal astigmatism on surgical outcomes ...

Correction of astigmatism after keratoplasty with toric IOL
Modern technologies in ophtalmologyIntroduction. Postkeratoplasty astigmatism is a common complication of penetrating keratoplasty (PKP), leading to a significant decrease in vision. Correction of high astigmatism is a challenging task. One of the modern and effective methods is phacoemulsification of cataracts (PEС) with implantation of a toric intraocular lens (TIOL). Purpose.
