Summary

MAIN OBJECTIVE: To assess the influence of residual astigmatism on visual acuity in the different lens foci in patients operated on for cataracts with a trifocal intraocular lens implant.

SECONDARY OBJECTIVE: To study the influence of residual astigmatism on the visual quality of the patient in the far focus and to determine if there are differences of affectation in the two study groups.

Conditions

  • Cataract After
  • Astigmatism
  • IOL
  • Visual Acuity

Interventions

OTHER

Kind of trifocal IOL

Patients will be divided between groups based on pre-surgery corneal astigmatism. Group FineVision is made up of patients with corneal astigmatism less than 1 D. Groups FineVision Toric is made up pf patients with corneal astigmatism more than 1.25 D
