简要总结

This will be a prospective observational, ethics committee approved study where patients undergoing routine cataract surgery will have bilateral implantation of the intraocular lens (LuxSmart, Bausch & Lomb). The device under investigation is CE-mark approved and commercially available. The device under investigation and all study products, including the devices used for the study examinations, will be used within the intended use specifications from the manufacturer. In addition, no invasive or other burdening examinations will occur for the patient.

Investigator is accredited and experienced cataract surgeon and researchers who have been involved in similar studies in the past.

The device under investigation LuxSmart (Bausch & Lomb) is a hydrophobic, acrylic copolymer containing UV absorber intraocular lens (IOL). The IOLs will be implanted as part of the routine cataract surgery on patients suffering from cataract development.

In total 30 patients will be recruited for this first clinical experience and receive bilateral implantation of the LuxSmart. The maximum time between 1st and 2nd eye implantation is 30 days, some patients may receive bilateral implantation on the same day. However there will be a minimum of 1 week between the implantations in the first 10 patients.

入选标准

  • Cataractous eyes with no comorbidity;
  • Calculated IOL power is within the range of the study IOLs;
  • Male or female adults ages 50 years or older on the day of screening who have cataract(s) in one or both eyes;
  • Regular corneal astigmatism ≤1.5D (measured by an automatic keratometry) in one or both eyes;
  • Clear intraocular media other than cataract;
  • Dilated pupil size large enough to visualize IOL axis markings postoperatively
