Medicontur hydrophilic posterior chamber monofocal intraocular lens (IOL) is 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 640AD IOLs mono- or binocularly between December 2021 - December 2022. Data from five visits will be collected: * Baseline preoperative (maximum 30 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 12 months postoperative and preoperative results.
Time frame: 12 months postoperatively
Monocular uncorrected distance visual acuity (UDVA)
To compare monocular uncorrected distance visual acuity (UDVA) at 12 months postoperative and preoperative status.
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 at 12 months postoperative and preoperative status.
Time frame: 12 months postoperatively
Manifest residual refraction
To compare residual SPH at 12 months postoperative and preoperative status. (Residual CYL and axis are not applicable, as it is a monofocal IOL, that does 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 perception and scotopic vision at 12 months postoperatively. The results are evaluated according to the official evaluation guide.
Time frame: 12 months postoperatively
