简要总结

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.

结局指标

主要结局

Best corrected visual acuity result

时间窗: up to 21 days post-surgery

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

Ocular staining score result

时间窗: up 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.

Ocular Surface Disease Index survey result

时间窗: up to 21 days post-surgery

a standard survey that patient will preform at each visit

次要结局

  • Shirmer test 1 measurement(up to 21 days post-surgery)
  • Intraocular pressure measurement(up to 21 days post-surgery)
