Eye Surface Properties After Using Dexamethasone Drops With and Without Preservatives in Patients After Cataract Surgery (EyeSurface)

Eye Surface Properties After Using Dexamethasone Drops With and Without Preservatives in Patients After Cataract Surgery

Assessment of the Eye Surface and Subjective Symptoms After Using Dexamethasone Drops With and Without Preservatives in Patients After Cataract Surgery

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.

Usage of preservative-free eye drops in comparison to the standard preserved drops with dexamethasone 0.01%.

standard staining score - a scale used with the fluorescein stain; higher value expres more severe outcome, normal values are around 0-1.

time to break-up the tear film after the instilation of the fluorescein eye drop (evaluated 3 fold and the mean will be taken into account)

Scale that requires both fluorescein and lissamine green staining profile assesment - used in the standardised manner

test that evaluate the amount of tears (in mm on the test paper) that are produced within 5 minutes and are evaluated under the anesthesia

the standardised SUN assesment of the anterior chamber cell intensity will be preformed - a standardised scale

Inclusion Criteria: cataract surgery required defined previously by the eye-care specialist good and clear visibility of the anterior chamber in the pre-surgery status (enables investigators to assess the anterior chamber cell intensity) consent to the study protocol Exclusion Criteria: diagnosed glaucoma diagnosed previous allergy diagnosed diabetic retinopathy or maculopathy previously diagnosed dry eye disease that requires treatment with multiple artificial tears permanent usage of the eye drops other than artificial tears non-compliance to the study protocol
