      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Type of Randomization: We used simple randomization with an individual unit of allocation.
Randomization Sequence Generation: The random allocation sequence was generated using a computer-generated random number table.
Allocation Concealment: Allocation concealment was ensured using sequentially numbered, opaque, sealed envelopes (SNOSE), which were prepared by an independent assistant not involved in the study.
Stratification: No stratified or block randomization was used in this study.
The randomization procedure was designed in consultation with an epidemiologist to ensure methodological rigor, Blinding description: Neither participants nor the clinical evaluator will know whether the administered eye drop contains topical statin or placebo. both formulations have identical appearance, color, odor, viscosity, and packaging, and will be labeled with random allocation codes generated by a statistician who is otherwise uninvolved in the study. Assignment of each bottle to individual subjects will follow the permuted-block randomization list; only the pharmacist responsible for labeling and an independent data-safety officer will have access to the code key. All ocular examinations and outcome assessments will be performed by a single cornea specialist masked to group allocation. The randomization code will remain sealed until after completion of data collection and primary statistical analysis, except in the event of a serious adverse event that requires unblinding for patient safety.</study_design>

      <i_freetext>Intervention 1: Intervention group: one affected eye of each patient will be enrolled in the study as the treatment eye. In addition to standard care, including eyelid hygiene and warm compresses, topical Atorvastatin eye drop (50 µM) will be administered to the treatment eye at a dosage of one drop four times a day.". Intervention 2: Control group: In the control group, only one affected eye of each patient will be included to receive the placebo. In addition to routine treatment, including eyelid hygiene, a topical placebo drop identical in appearance and composition to the intervention drop but without the active ingredient atorvastatin will be administered to the study eye, one drop four times daily.</i_freetext>

      <sec_outcome>Dry eye questionnaire (DEQ5) score. Timepoint: Measurement of DEQ5 score at baseline (prior to the intervention) and at weeks 4, 8, and 12 after initiation of the drug or placebo. Method of measurement: A self-administered questionnaire used to assess the presence and severity of dry eye symptoms.</sec_outcome>
      <sec_outcome>Meibomian gland expressibility. Timepoint: Measurement of Meibomian gland expressibility at baseline (prior to the intervention) and at weeks 4, 8, and 12 after initiation of the drug or placebo. Method of measurement: Evaluation of the meibomian glands in the lower eyelid is performed by applying approximately 1.20 grams per square millimeter of pressure to the nasal, central, and temporal regions. Lipid secretion from the gland orifices is assessed and graded on a scale from 0 to 4:Grade 0: secretion from more than 75% of the glands; Grade 1: secretion from 50–75% of glands; Grade 2: secretion from 25–50% of glands; Grade 3: secretion from less than 25% of glands; Grade 4: no secretion from any gland. In addition, the quality of the expressed meibum is graded as follows: Grade 0: clear; Grade 1: cloudy; Grade 2: cloudy with debris or granular texture;G rade 3: thick and toothpaste-like; Grade 4: waxy.</sec_outcome>
      <sec_outcome>Tear meniscus height. Timepoint: Measurement of Tear meniscus height at baseline (prior to the intervention) and at weeks 4, 8, and 12 after initiation of the drug or placebo. Method of measurement: Measurement of tear film height using the slit-lamp biomicroscope.</sec_outcome>
