Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to assess if treatment with Lacrimera® eye drops (Croma-Pharma GbmH, Leobendorf, Austria) during and/ or after cataract surgery has a positive effect on the ocular surface compared to control group.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prior to surgery, pre-assessment measurements will be performed in the same fashion as for non-study patients. Patients will be randomized to one of the 3 groups in a 1:1:1 fashion using an online randomization tool (www.randomizer.org, list randomizer).

Surgery is performed in topical anaesthesia. Right after topical anaesthesia, patients allocated to Group 3 will receive 1 drop of Lacrimera® in the study eye. Injection of viscoelastic substance (OVD), capsulorhexis, phacoemulsification, and coaxial irrigation/ aspiration of cortical material are performed as standard procedure. After IOL implantation the OVD will be removed and at the end of the surgery, stromal hydration will be performed to the incision as a routine procedure to seal the wound. Right after the wound is sealed, patients allocated to group 2 and group 3 will receive 1 drop of Lacrimera® in the study eye. Postoperative standard medication (Bromfenac gtt., twice a day for 4 weeks) will be prescribed for all groups.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1

15 patients will be included in group 1 (no additional treatment)

Group Type NO_INTERVENTION

No interventions assigned to this group

Group 2

15 patients will be in group 2 (treatment directly after cataract surgery in the surgical theatre)

Group Type EXPERIMENTAL

Lacrimera

Intervention Type DEVICE

A new preservative-free formulation of eye drops consists of a novel biopolymer, chitosan-N-acetylcysteine (C-NAC; Lacrimera®, Croma-Pharma GmbH, Leobendorf, Austria), which electrostatically binds to the mucine layer of the tear film forming a glycocalyx-like structure.

Group 3

15 patients will receive treatment after local anaesthesia (pre-operatively) and directly after cataract surgery (group 3)

Group Type EXPERIMENTAL

Lacrimera

Intervention Type DEVICE

A new preservative-free formulation of eye drops consists of a novel biopolymer, chitosan-N-acetylcysteine (C-NAC; Lacrimera®, Croma-Pharma GmbH, Leobendorf, Austria), which electrostatically binds to the mucine layer of the tear film forming a glycocalyx-like structure.

* Previous ocular surgery or trauma in the study eye within 6 months of the cataract surgery
* Active ocular infection or inflammation
* Pregnancy (pregnancy test will be taken in women of reproductive age)
