Detailed Description:
This study evaluated the safety and effectiveness of the Hoya Surgical Optics iSert Model 251 IOL following primary implantation for the visual correction of aphakia in adults in whom the cataractous lens has been removed by phacoemulsification. Results from this prospective, multicenter clinical trial will be used to support a PMA supplement for the iSert® 251 IOL.

Inclusion Criteria:

  • Have been diagnosed with cataract for which phacoemulsification extraction and posterior chamber IOL implantation is indicated
  • Have clear intraocular media
  • Have potential Best Corrected Visual Acuity of 20/40 or better
  • Have preoperative Best Spectacle-Corrected visual acuity of 20/40 or worse

Exclusion Criteria:

  • Have ocular pathology or abnormalities that do or are expected to reduce best corrected visual acuity in the operative eye during the study period
  • Are monocular
  • Have current ocular infection
