Study summary

The goal of this clinical trial is to compare the administration of 2 drugs, cyclosporine 0.05% (Restasis) and Lifitgrast (Xiidra) before PRK, in reducing the ocular surface symptom of patients after PRK. The main questions it aims to answer are:

1- Does the use of cyclosporine 0.05% (Restasis) and Lifitgrast (Xiidra) before photorefractive keratectomy surgery (PRK) reduce ocular surface symptom such as eye pain, redness, and inflammation in conjunctivitis in patients? Researchers will compare cyclosporine 0.05% (Restasis) and Lifitgrast (Xiidra) to a placebo (Artelac artificial tears) to see if cyclosporine 0.05% and Lifitgrast works to reduce ocular surface symptom.

Participants will:

Take drug cyclosporine 0.05% and Lifitgrast or a Artelac 30 minutes before surgery Visit the clinic 6 hours, one day, three days and one week after photorefractive keratectomy (PRK) for checkups and tests

Read the detailed description

Considering the increasing importance of reducing eye symptoms of patients after PRK surgery and the impact of this issue on the quality of life of patients, as well as the lack of sufficient studies on the effect of different drugs in this field and comparing their effects, which ultimately lead to the decision and clinical application of this Regarding the category of drugs, the present study aims to compare the administration of 2 drugs, cyclosporine 0.05% and Lifitgrast before PRK, in reducing the eye symptoms of patients after PRK.

In this study, 15 minutes before the start of photorefractive keratectomy surgery, we divide the patients into 3 random groups and according to the following plan, we put the drops into the eyes of the patients.

The first group: one eye drop cyclosporine 0.05% - opposite eye drop Lifitgrast The second group: one eye with 0.05% cyclosporine drops - the opposite eye with Artlac artificial tear drops The third group: one eye with Liffitgrast drops - the opposite eye with Artlac artificial tear drops Patients will be evaluated and examined according to variables 6 hours, one day, three days and one week after the operation. To check the symptoms of patients from standard questionnaires including Ocular surface disease index (OSDI), visual analogue scale (VAS) Wong-Baker FACES, Efron is used.
