Arm && Interventions

Group	Intervention	Description
Tixel Group	Tixel C	Tixel C Group: Screening and baseline visits, Treatment- 3 treatment sessions, followed by 2 Follow up sessions, 1and 3 months after last treatment visit. Subject will be questioned about Discomfort and Pain Questionnaires (self-assessed) and OSDI questionnaire.
LipiFlow	LipiFlow	LipiFlow: Screening and baseline visits, Treatment- 1 single treatment session, followed by 2 Follow up sessions, 1and 3 months after the last treatment visit. Subject will be questioned about Discomfort and Pain Questionnaires (self-assessed) and OSDI questionnaire.

Primary Outcome Measures

Name	Time	Method
Score and Change From Baseline in Tear Break Up Times (TBUT), as Assessed by a Masked Rater	Tixel arm: Baseline and 4 weeks after last treatment (8 weeks post baseline). LipiFlow arm: Baseline and 4 weeks after treatment (4 weeks post baseline).	Change from baseline to the 4-weeks follow-up exam in Tear Break Up Times (TBUT), as assessed by a masked rater. TBUT - Tear Break-Up Time, is a clinical test used to evaluate the stability of the tear film on the surface of the eye. It measures the time it takes for dry spots to appear on the cornea after a blink. A shorter TBUT indicates a more unstable tear film, which can be a sign of dry eye disease or other ocular surface disorders. Tear Break-Up Time (TBUT) is typically scored by the time (in seconds). The general interpretation of TBUT scores is as follows: Normal TBUT: More than 10 seconds Borderline TBUT: 5 to 10 seconds Abnormal/Low TBUT: Less than 5 seconds
Comparison of the Incidence of Device-related Adverse Events for the Two-treatment Arms.	Tixel arm: Baseline to 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline to 12 weeks after treatment (12 weeks post baseline).	Comparison of the incidence of device-related adverse events (e.g., increase in the lid margin such as development of floppy eyelids, entropion or ectropion; and lash integrity) for the two-treatment arms.

Secondary Outcome Measures

Name	Time	Method
Score on a Scale and Change From Baseline in Patient Symptoms Using Ocular Surface Disease Index (OSDI).	Tixel arm: Baseline to 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline to 12 weeks after treatment (12 weeks post baseline).	Change from baseline in patient symptoms using Ocular Surface Disease Index (OSDI) at 4-weeks and 12-weeks follow-up exam. The Ocular Surface Disease Index (OSDI) is a questionnaire designed to assess the severity of dry eye disease. OSDI Questionnaire The questionnaire consists of 12 questions divided into three subscales: Ocular Symptoms Visual Functioning Environmental Triggers Scoring System The scoring for the OSDI is based on a scale from 0 to 100, where higher scores indicate more severe symptoms. Each question is scored as follows: 0: None of the time 1. Some of the time 2. Half of the time 3. Most of the time 4. All of the time Interpretation of OSDI Scores The OSDI scores are generally interpreted as follows: 0-12: Normal or no dry eye 13-22: Mild dry eye 23-32: Moderate dry eye 33-100: Severe dry eye
Score on a Scale and Change From Baseline in Meibomian Gland Score (MGS), as Assessed by a Masked Rater.	Tixel arm: Baseline to 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline to 12 weeks after treatment (12 weeks post baseline).	score on a scale at baseline, 4-weeks and 12-weeks follow-up exam in Meibomian Gland (MGS), as assessed by a masked rater. The Meibomian Gland Score (MGS) is a clinical tool used to evaluate the function of the meibomian glands. Scoring Criteria Each gland is assessed and scored based on the quality of the expressed secretion: 0: No secretion 1. Inspissated 2. Cloudy 3. Clear liquid Interpretation of MGS Minimal MGS score = 0 in each eye (15 glands evaluated in each eye) Maximal MGS score = 45 in each eye (15 glands evaluated in each eye) Low MGS: (below 12) Indicates poor function or obstruction of the meibomian glands, suggesting MGD.
Overall Changes From Baseline in Tear Break Up Times (TBUT), as Assessed by a Masked Rater.	Tixel arm: Baseline and 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline and 12 weeks after treatment (12 weeks post baseline).	Changes from baseline to the 12-weeks follow-up exam in Tear Break Up Times (TBUT), as assessed by a masked rater. BUT - Tear Break-Up Time, is a clinical test used to evaluate the stability of the tear film on the surface of the eye. It measures the time it takes for dry spots to appear on the cornea after a blink. A shorter TBUT indicates a more unstable tear film, which can be a sign of dry eye disease or other ocular surface disorders. Tear Break-Up Time (TBUT) is typically scored by the time (in seconds). The general interpretation of TBUT scores is as follows: Normal TBUT: More than 10 seconds Borderline TBUT: 5 to 10 seconds Abnormal/Low TBUT: Less than 5 seconds
Score on a Scale During Treatment Discomfort and Pain Questionnaires (Each Self-assessed by VAS)	Tixel arm: 4 weeks (treatment 1- day 0, treatment 2- 2 weeks, treatment 3- 4 weeks). LipiFlow arm: On treatment day - day 0 (only one treatment for this arm)	Discomfort and Pain from the treatment (Tixel or LipiFlow) using the questionnaires assessed by the subject. These are visual analogue scale (VAS) questionnaires using a scale from 0-10 to assess eye discomfort and pain. Both questionnaires are to be self-assessed by the patient immediately following treatment. Interpetation for the assessment: score 0- no discomfort / pain score 5 - moderate discomfort / pain score 10 - worst possible discomfort / pain
Corneal Fluorescein Staining Slit Lamp Evaluation Scores and Change From Baseline	Tixel arm: Baseline to 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline to 12 weeks after treatment (12 weeks post baseline).	Changes from baseline following treatment for the test and control devices for the following assessments: Ocular Surface Staining (to evaluate the integrity of the corneal epithelium by identifying areas of damage or staining) Grading scale: 0 = Normal - No staining 1. = Mild - Superficial stippling micropunctate staining 2. = Moderate - Macropunctate staining with some coalescent areas 3. = Severe - Numerous coalescent macropunctate areas and/or patches 5 regions (superior, temporal, central, nasal, and inferior) are graded for each eye. total score range from 0 -15.
The Mean Changes From Baseline in IOP for All Eyes on the Tixel and Lipiflow Arms	Tixel arm: Baseline to 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline to 12 weeks after treatment (12 weeks post baseline).	the IOP values changes from baseline, respectively, for all visits, per treatment arm.
Lissamine Green Staining Scores and the Changes From Baseline	Tixel arm: Baseline to 12 weeks after last treatment (16 weeks post baseline). LipiFlow arm: Baseline to 12 weeks after treatment (12 weeks post baseline).	Changes from baseline following treatment for the test and control devices for the following assessments: Lissamine staining scores (to assess the health of the conjunctival and corneal epithelium, particularly in dry eye disease, by identifying areas of damaged or dead cells). Grading scale: 0 = Normal - No staining 1. = Mild - Superficial stippling micropunctate staining 2. = Moderate - Macropunctate staining with some coalescent areas 3. = Severe - Numerous coalescent macropunctate areas and/or patches 6 regions (nasal, superior nasal, inferior nasal, temporal, superior temporal, inferior temporal) are graded for each eye. total score range for each eye is 0-18.
