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 June 2022 - September 2023. 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

Monocular corrected distance visual acuity (CDVA)
To compare monocular corrected distance visual acuity (CDVA) between groups implanted with 690AD and 690ADY monofocal IOLs at 12 months postoperatively.
Time frame: 12 months postoperatively
Monocular uncorrected distance visual acuity (UDVA)
To compare monocular uncorrected distance visual acuity (UDVA) between groups implanted with 690AD and 690ADY monofocal IOLs 12 months postoperatively.
Time frame: 12 months postoperatively
UDVA and CDVA
To compare percentage of eyes that achieve monocular UDVA and monocular CDVA within logMAR 0.0 or 0.3 between groups implanted with 690AD and 690ADY monofocal IOLs at 12 months postoperatively.
Time frame: 12 months postoperatively
Manifest residual refraction
To compare SPH between groups implanted with 690AD and 690ADY monofocal IOLs 12 months after IOL implantation. CYL and axis are not applicable, as the investigational- and comparator devices are monofocal IOLs, that do not correct astigmatism.
Time frame: 12 months postoperatively
Patient satisfaction
Visual Function Questionnaire 25 (National Eye Institute) is used to evaluate overall satisfaction, subjective perception of colour and scotopic vision at 12 months postoperatively. The results are evaluated according to the official evaluation guide.
Time frame: 12 months postoperatively
