Details and patient eligibility

About

The purpose of the current study was to compare the visual performance after bilateral implantation of the Panoptix IOL , or the AT LISA IOL or Tecnis Symfony IOL . The focus was on intermediate vision, defocus curves, and contrast sensitivity.

50 participants in 3 patient groups

panoptix PANFOCAL intraocular lens

Active Comparator group

Description:

panoptix PANFOCAL intraocular lensis a single-piece aspheric non-apodized diffractive panfocal IOL that distributes light energy to three focal points in both small and large pupil conditions

Treatment:

Procedure: phacoemulsification with implantation of presbyopia correcting IOL

Trifocal Diffractive the AT LISA intraocular lens

Active Comparator group

Description:

Trifocal Diffractive the AT LISA is a preloaded single-piece aspheric diffractive trifocal IOL and made of hydrophilic acrylic with a hydrophobic surface with an ultraviolet absorber. This aspheric IOL is aberration -correcting in order to reduce and compensate for corneal spherical aberrations.

Treatment:

Procedure: phacoemulsification with implantation of presbyopia correcting IOL

Symphony EDOF (extended depth of focus) intraocular lens

Active Comparator group

Description:

SYMPHONY EDOF intraocular lens is a single-piece aspheric biconvex hydrophobic acrylic IOL with a 6.0 mm optic and an 13.0 mm overall diameter. This IOL consists of a wavefront-designed anterior aspheric surface (negative spherical aberration of -0.27 mm to counterbalance the net positive spherical aberration from cornea) and a posterior achromatic diffractive surface with echelette design.

Treatment:

Procedure: phacoemulsification with implantation of presbyopia correcting IOL
