Wavefront Analyzes and Visual Performance of Three Multifocal Intra-ocular Lenses

Phase 1 Study of Ocular Aberrations and Visual Performance of Eyes Implanted With Three Multifocal Intra-ocular Lenses

The purpose of this study is to determine if differences in the design of multifocal intra-ocular lenses would mean different values of higher-order aberrations and different performance in objective parameters such as modulation transfer function.

Inclusion Criteria:

• Patients with bilateral visually significant cataract with corneal astigmatism lower than 1.0D

Exclusion Criteria:

• Any ocular diseases, such as:

  • corneal opacities or irregularity
  • dry eye
  • amblyopia
  • anisometropia
  • glaucoma
  • retinal abnormality

• Surgical complications

• IOL tilt

• IOL decentration greater than 0.4 mm (estimated by retroillumination)

• Incomplete follow-up
