Cataract surgery with toric intraocular lenses in patients with distorted cornea
Main Article Content
Abstract
Cataract surgery in patients with distorted cornea is a challenge for the surgeon. Cornea with irregular astigmatism and dislocation of the corneal centre may result in a large refractive error after cataract surgery. It is important to assess the patient carefully, analyzing the corneal topography, and selecting a minimally invasive surgery that does not provoke secondary changes in the asymmetry of the cornea. The use of toric intraocular correction for patients suffering from significant distortion of the cornea and corneal astigmatism is a matter of difficulty stemming from weaker corneal hysteresis and instability of the corneal shape.
