Arms and Interventions
Participant Group / Arm |

Experimental: TriLift
Combination of Dynamic Muscle Stimulation and Radiofrequency
|
Dynamic Muscle Stimulation combined with tripolar Radiofrequency, administered on the skin of the inferior orbital rim and below the lower eyelids
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Impaired blink quality
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
binary (yes/no) variable, based on clinical estimation of the study investigator who will use a combination of two complementary tests (the lower lid distraction test and the snap-back test) to reach a yes/no decision.
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Eyelid appearance
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
Biomicroscopy with the slit lamp; normal, mild, moderate, severe
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Overall blink quality
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
Subjectively assessed by the study investigator; normal, mildly impaired, moderately impaired, severely impaired
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Margin to Reflex Distances MRD1 and MRD2
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
Distances from the margins of the upper and lower lids to the central corneal reflex, in millimeters
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
modified Meibomian Gland Score
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
15 meibomian glands along the lower lid (5 nasal + 5 central + 5 temporal) will be gently expressed with the dedicated expression forceps.
Each gland will be scored 0 to 3, as follows: 0 = clear liquid meibum; 1 = cloudy liquid meibum; 2 = inspissated meibum; 3 = blocked).
The modified Meibomian Gland score will be evaluated as the sum of scores for these 15 glands.
Hence, the minimal value is 0 (all 15 glands express a clear liquid meibum), and the maximal value is 45 (all 15 glands are blocked).
A decrease in the modiified Meibomian Gland Score means that the functionality of meibomian glands improved, and that the condition of the patient improved.
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Ocular Surface Disease Index
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
Symptoms will be self-evaluated with the Ocular Surface Disease Index questionnaire.
Twelve (12) questions will be asked about visual difficulties experienced by the subject during the past week.
Each question will be scored 0 (none of the time), 1 (some of the time), 2 (half of the time), 3 (most of the time) or 4 (all the time).
The Ocular Surface Disease Index will be calculated as the sum of scores times 25, divided by the number of questions answered.
An increase in the Ocular Surface Disease Index means that the symptoms are reduced and that the condition of the patient improved.
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Corneal sensitivity
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
Measured with an esthesiometer; device settings: 1 to 6
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Blink rate
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
Blinks per minute during a video-watching task
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Degree of eyelid closure
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
full, or maximal vertical height of the palpebral fissure measured in mm
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Teat Breakup time
Time Frame: 7 weeks after baseline (4 weeks after the 4th treatment)
|
Time between full blink and first appearance of a break in a fluorescein-stained eye
|
7 weeks after baseline (4 weeks after the 4th treatment)
|
Adverse events
Time Frame: Throughout the study and up to 7 weeks after baseline (4 weeks after the 4th treatment)
|
Incidence and type of adverse events
|
Throughout the study and up to 7 weeks after baseline (4 weeks after the 4th treatment)
|
BCVA
Time Frame: At baseline, at 1 week after baseline (immediately before the second treatment), at 2 weeks after baseline (immediately before the third treatment), at 3 weeks after baseline (immediately before the fourth treatment) and at 7 weeks after baseline
|
Best-corrected visual acuity, using an ETDRS chart (20/20, 20/25, 20/32,20/40,20/50,20/63, 20/80, 20/100, 20/200, 20/400, where 20/20 is considered perfect vision and 20/400 is considered legal blindness)
|
At baseline, at 1 week after baseline (immediately before the second treatment), at 2 weeks after baseline (immediately before the third treatment), at 3 weeks after baseline (immediately before the fourth treatment) and at 7 weeks after baseline
|
Pain/Discomfort
Time Frame: Immediately after a treatment session
|
Pain.discomfort will be self-reported with a visual analog scale (0 to 100), with 0 representing no pain/discomfort and 100 representing intolerable pain/discomfort.
A decrease in this visual analog score represents an improvement in the perception of pain/discomfort.
|
Immediately after a treatment session
