Conditions

Cataract
Surgical Injury
Interventions
Other: preservative-free solution of standard post-cataract eye drops
Registration Number
NCT05753787
Lead Sponsor
Spektrum Center of Clinical Ophthalmology
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Best corrected visual acuity resultup to 21 days post-surgery

best corrected visual acuity evaluated with standard ETDRS for distant and for near vision

Ocular staining score resultup to 21 days post-surgery

standard staining score - a scale used with the fluorescein stain; higher value expres more severe outcome, normal values are around 0-1. Overal information can be found: https://entokey.com/a-simplified-quantitative-method-for-assessing-keratoconjunctivitis-sicca-from-the-sjogrens-syndrome-international-registry/

Ocular Surface Disease Index survey resultup to 21 days post-surgery

a standard survey that patient will preform at each visit

Secondary Outcome Measures
NameTimeMethod
Shirmer test 1 measurementup to 21 days post-surgery

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

Intraocular pressure measurementup to 21 days post-surgery

Intraocular pressure measurement preformed by standard tonometer

Anterior chamber cell intensity measurementup to 21 days post-surgery

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

SICCA scale assessmentup to 21 days post-surgery

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

Fluorescein Break-up Time assessmentup to 21 days post-surgery

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)
