Our study

The design

This study is a prospective, single arm, single center, open label study.

The aim of this study is to evaluate safety and performance of the INTENSITY IOL.

Participants

Population

Patients diagnosed with cataract who require cataract surgery procedure that meet the inclusion criteria.

Inclusion criteria

Age 45 – 75 years.
Bilateral age-related cataracts, require bilateral cataract. 
Axial length of 22-24.5mm. 
Corneal astigmatism < 0.75D, regular.
Post-op BCVA expected 0.3 logMAR or better. 
Patient motivated for multifocal IOL
No retinal or optic nerve abnormalities

Highlights

Conclusions

  • A promising new lens design that may truly provide a good range of focus and spectacle freedom to pseudophakic patients.
  • Results show an excellent defocus curve, with exceptionally good near and intermediate vision without compromising the far vision.

  • Average visual acuity above 0.05 (6/6.7) throughout infinity to 40 cm.

  • High patient satisfaction.
