Outcome Measures

Primary Outcomes (1)

  • Anterior chamber depth (ACD)

    The change in anterior chamber depth (ACD) before and after cataract surgery will be measured using the IOL Master 700 and compared between the two different IOLs.

    12 months

Secondary Outcomes (1)

  • Distance visual acuity

    12 months

Study Arms (1)

Monofocal IOL

EXPERIMENTAL

Patients will be implanted with two different monofocal lenses (Clareon and AcrySof) during cataract surgery

Procedure: Cataract surgery

Interventions

During cataract surgery the patient is implanted with the monofocal IOL Clareon in one eye and the monofocal IOL AcrySof in the contralateral eye

Monofocal IOL
