Feasibility of IPL for Reducing Dry Eye Symptoms Caused by MGD

February 1, 2017 updated by: Lumenis Be Ltd.

Feasibility of Intense Pulsed Light (IPL) for Reducing Dry Eye Symptoms Caused by Meibomian Gland Dysfunction (MGD)

The purpose of this study is to evaluate if, in patients with meibomian gland dysfunction (MGD), treatment with the Lumenis M22 Intense Pulsed Light (IPL) system causes a reduction in dry eye symptoms post-treatment, compared to pre-treatment.

Detailed Description

The IPL module has FDA clearance (K142860) for a wide range of indications, including benign cavernous hemangiomas, benign venous malformations, telangiectasia, port-wine stains, pigmented lesions and erythema of rosacea. As shown by a retrospective study, in over 85% of the cases, using IPL in subjects with ocular rosacea also alleviated the symptoms of DED caused by MGD. No serious adverse events were recorded, suggesting that IPL therapy administered close to the ocular orbits is safe (provided that the eyes are shielded). However, the above mentioned study was retrospective. Therefore, additional evidence is needed in order to substantiate the hypothesis that alleviation of MGD symptom was facilitated by IPL treatments.

The aim of the current study is to assess the safety and efficacy of IPL treatment for reducing the symptoms of dry eye disease (DED) in subjects with MGD. The study hypothesis is that in a study population of subjects diagnosed with moderate to severe MGD, 4 sessions of IPL therapy with the M22 system, followed by expression of the MGs, will cause a significant increase in tear break-up time post-treatment, compared to pre-treatment.

Intervention: Treatment of dry eye symptoms secondary to MGD with the M22-IPL system
The IPL hand piece operates at a spectrum of 400-1200nm with 7 different filters that can be easily inserted to the hand piece to treat different conditions. The IPL hand piece also includes 2 different sapphire cooled light guides of 8x15mm and 15x35mm. The cut-off filters that will be used for this evaluation are filters blocking wavelengths of 560 and 595 nm.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Tear Break-up time in seconds, using the standard Fluorescein staining method
Time Frame: from Baseline to 3 weeks after the 3rd treatment and 3 weeks after the fourth/final treatment
The number of seconds that elapse between the last blink of the eye to the appearance of the first dry spot in the tear film
from Baseline to 3 weeks after the 3rd treatment and 3 weeks after the fourth/final treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Corneal fluorescein staining score, using the Baylor Scheme
Time Frame: from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
The cornea will be viewed and logically divided to 5 zones: central, superior, inferior, temporal and nasal. In each of the 5 zones, grading will be as follows: 0 dots = 0; 1-5 dots = 1; 16-30 dots = 3; > 30 dots = 4; One point will be added to the score in case of 1 area of confluent staining. Two points will be added to the score in case of two or more areas of confluent staining. The total score is the sum of scores in the 5 zones
from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
Meibomian gland score, using the "Abbreviated MGD grading system for clinical trials"
Time Frame: from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
  1. Thickening of the upper lid margin (0-3, where 0 is normal and 3 is severe). A value of at least 1 (mild) is consistent with DED.
  2. Vascularity of the upper lid margin (0-3, where 0 is normal and 3 is severe engorgement). A value of at least 1 (mild engorgement) is consistent with DED.
  3. Number of telangiectasias (0-3, where 0 = none, 1 = single, 2 = two to four and 3 = above four). A value of at least 2 (2-4 telangiectasias) is consistent with DED.
  4. Of the central 10 glands of the upper eyelid- number of plugged glands: a value of at least 2 is consistent with DED. The total score is computed by summing the scores of the 8 categories above.
from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
Subjective symptoms, using the SPEED questionnaire
Time Frame: from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment

SPEED is a validated questionnaire for quantifying the subjective symptoms of DED. The questionnaire will be filled by the study investigator (with questions answered by the subject). In 4 symptoms are evaluated: (1) dryness, grittiness or scratchiness; (2) Soreness or Irritation; (3) Burning or watering; and (4) Eye fatigue. Two types of questions are asked about these symptoms: frequency and severity.

In the Frequency questions, subjects evaluate the 4 symptoms above on a 0-3 scale: 0 = Never; 1 = Sometimes; 2 = Often; and 3 = All the time.

In the Severity questions, subjects evaluate the 4 symptoms above on a 0-4 scale: 0 = No problems; 1 = Tolerable (not perfect but not uncomfortable); 2 = Uncomfortable (irritating but does not interfere with my day); 3 = Bothersome (irritating and interferes with my day); and (4) Intolerable (unable to perform my daily tasks). The total score is the sum of the Frequency answers and the Severity answers.

from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
Tear Osmolarity in milliosmol/liter, using a lab-on-a-chip system to simultaneously collect and analyze the electrical impedance of a tear sample
Time Frame: from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
In this current study, tear osmolarity will be measured using a lab-on-a-chip system to simultaneously collect and analyze the electrical impedance of a tear sample (TearLab, San Diego, CA, USA). A small tear sample of 50 nL will be collected from the lower meniscus, using a disposable test chip by passive capillary action, and transferred to the device. Several seconds after the transfer, readings will be given in milliOsmol/L
from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
Lipid Layer Thickness in nanometers, using an interferometer
Time Frame: from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
lipid layer thickness will be measured using an interferometer. In interferometry, when white light is projected over the cornea, a color interference pattern is produced due to specular reflection at the lipid-aqueous interface. The reflected colors from the tear film are captured on a high-resolution video. Each recorded pixel is analyzed, and compared with a color progression table. The output is expressed as interference color units (ICUS), which correlate with lipid layer thickness
from Baseline to 3 weeks after the 3rd treatment; 3 weeks after the fourth/final treatment; 6 weeks after the final treatment
