Postoperative Refraction and Patient Satisfaction after Bilateral Implantation of Presbyopia-Correcting Intraocular Lenses

Financial Disclosure: the author of this e-Poster is a Consultant to Alcon and has received research funding and presentation support from Alcon Research, Ltd.


Purpose

Purpose

  • To evaluate predictability of refractive outcomes and patient satisfaction after bilateral implantation of presbyopia-correcting intraocular lenses with aspheric apodized diffractive or aspheric and spherical accommodative optics.


Methods

Methods

  • Cataract patients with <1 diopter of corneal astigmatism underwent on-label, bilateral implantation of:

    • ReSTOR IQ +3.0D add IOLs

    • Crystalens AO IOLs

    • Crystalens HD IOLs

  • Refractive enhancements were not permitted before study end

  • 6-month, prospective, randomized, subject-masked study

    • 3 month interim results are presented here

  • Study conducted at four-centers in the US


Methods1

Methods

  • Manifest refraction (MR) was measured preoperatively and postoperatively at 1 and 3 months

  • Patients self-rating of bilateral vision (without glasses) was evaluated using the Cataract TyPE questionnaire*

  • Rating scale of 0 to 10 (0=best, 10=worst)

Self rating of uncorrected vision

Self-Rating of Uncorrected Vision

Mean ratings were highest for the apodized diffractive IOL group (+3.0 D),

followed by the aspheric (AO) and the spherical (HD) accommodating IOLS.

Conclusions

Conclusions

  • One and three months afterbilateral implantation of presbyopia-correcting IOLs, patients had:

    • more predictable refractive outcomes with aspheric apodized diffractive IOL than with the accommodative aspheric or accommodative spherical IOLs 

    • greater satisfaction with the aspheric apodized diffractive IOL than with the accommodative aspheric or the accommodative spherical IOLs
