Clinical Investigation of the Safety and Performance of Model 690AD and Model 690ADY Monofocal Intraocular Lens Implantation

June 10, 2024 updated by: Medicontur Medical Engineering Ltd

Retrospective, Non-interventional, Comparative Clinical Investigation of the Safety and Performance of 690AD and 690ADY Monofocal Intraocular Lens Implantation

Medicontur hydrophilic posterior chamber monofocal intraocular lens (IOLs) are indicated to improve vision at far distance in adults with cataract and/or ametropia (hyperopia, myopia), secondarily to removal of the crystalline lens.

The intraocular lens is intended to be surgically implanted into the eye with the purpose of restoring optical function in the aphakic eye to provide an optical system with high predictability of the precalculated dioptric power.

The study will be performed partially as a retrospective study with patients enrolled who had been implanted with 690AD or 690ADY IOLs mono- or binocularly between September 2021 - March 2022.

Data from five visits will be collected:

  • Baseline preoperative (maximum 90 days prior to surgery)- retrospective
  • IOL implantation Day 0 - retrospective
  • Postoperative visit at Day 1 (+/- 0 days) - retrospective
  • Postoperative visit at 1 month (+/- 2 weeks) - retrospective
  • Postoperative visit at 12 months (+/- 3 months) - consent and prospective visit
