NCT05213156

Brief Summary

After topical installation of one drop of 0.3% commercially available ofloxacin (Oxatrex®) four times at intervals of 15min in catarract patients with Dry Eye Disease, aqueous humour samples will be collected intraoperatively, one hour after the last installation. Concentration of ofloxacin in aqueous humour will be measured by HPLC-MS/MS.

Outcome Measures

Primary Outcomes (2)

  • DED severity

    DED severity will be determined during preoperative cataract evaluation.

    One day prior to cataract surgery, from 09:00am to 12:00pm

  • Concentration of ofloxacin in the aqueous humour

    After topical instillation of ofloxacin eye drops, aqueous humor samples will be collected intraoperatively and ofloxacin concentration will be determined by HPLC-MS/MS.

    Beginning of the cataract surgery, from 08:30am to 12:30pm

Secondary Outcomes (2)

  • Ocular Surface Disease Index (OSDI)

    One day prior to cataract surgery, from 09:00am to 12:00pm

  • Corneal staining

    One day prior to cataract surgery, from 09:00am to 12:00pm
