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.
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.
