Visual Function in Subjects Implanted With Advanced Technology Intraocular Lenses

• Conditions: Lenses, Intraocular

• Registration Number: NCT04916041
• Lead Sponsor: Clínica Rementería

Brief Summary

Multiple intraocular lens are nowadays available for implantation after cataract surgery. They use different technology to try to improve patient spectacle independence. It is necessary to better characterise the performence of each type of lens, as well as to define how they are affected by residual refractive errors. The purpose of this study is to evaluate visual function in patients implanted with different lenses (advanced monofocals, trifocals) in order to be able to recommend the best type of lens for each patient.
