The goal of this interventional, real world data study is to evaluate the impact of preservatives on the post-cataract ocular surface. The main question is to learn about an effect of preservatives on the eye surface. The study aims to answer some important questions: * if the usage of preservatives has an impact on the eye surface healing process after cataract surgery * if patient comfort and quality of life improve more or more rapidly with preservatives-free eye drops. Participants will be asked to undergo standard procedure of peri-cataract surgery care and in addition to survey about the ocular surface state. Researchers will compare group that takes preservatives-free dexamethasone 0.1% with standard dexamethasone 0.01% solution to see if post-surgery eye surface healing properties differ from both groups.

Best corrected visual acuity result
best corrected visual acuity evaluated with standard ETDRS for distant and for near vision
Time frame: up to 21 days post-surgery
Ocular staining score result
standard staining score - a scale used with the fluorescein stain; higher value expres more severe outcome, normal values are around 0-1.
