Intended Use

The iLux System is indicated for the application of localized heat and pressure therapy in adult patients with chronic diseases of the eyelids, including meibomian gland dysfunction (MGD), also known as evaporative dry eye.

Device Story

iLux System is a handheld device for eye care professionals (ECP) to treat meibomian gland dysfunction. It consists of a handheld instrument and a single-use sterile disposable component. The ECP positions the disposable behind the eyelid and uses a built-in magnifier to view the eyelid margin. The instrument uses lime-green and infrared LEDs to heat eyelid tissue to 40–42 °C, melting meibum. The ECP then applies manual compression to express the meibum. The instrument displays real-time inner eyelid temperature and compression force, allowing the ECP to titrate therapy. The device is powered by a rechargeable lithium-ion battery. By unclogging glands, the device aims to alleviate symptoms of evaporative dry eye.

Clinical Evidence

A randomized, 1:1 controlled clinical study of 142 subjects (284 eyes) compared iLux to LipiFlow. Primary endpoints (MGS, TBUT) and secondary endpoint (OSDI) showed significant improvement from baseline in both groups with no significant difference between groups at weeks 2 and 4. Safety endpoints included pain, discomfort, ocular surface staining, IOP, and BSCVA. Four device-related AEs occurred in the iLux arm, all self-limited and transient. Results support non-inferiority.

Technological Characteristics

Handheld instrument with single-use sterile disposable. Heating via lime-green and infrared LEDs. Powered by rechargeable lithium-ion battery. Disposable contact material: silicone. Sterilization: Ethylene Oxide (disposable). Software Level of Concern: Moderate. Connectivity: Standalone. Safety: Complies with IEC 60601-1 and 60601-2.

Indications for Use

Indicated for adult patients with chronic eyelid diseases, including meibomian gland dysfunction (MGD) or evaporative dry eye.

- The LipiFlow Thermal Pulsation System manufactured by TearScience, Inc. and cleared for commercial distribution under 510(k): K133127.
#### Device Description

The iLux System is a medical device intended for use by Licensed Eye Care Professionals (ECP) to apply localized heat and pressure therapy to adult patients' lower and/or upper eyelids. The il.ux System consists of a hand-held Instrument coupled to a single-use sterile Disposable component that is positioned behind the eyelid. The iLux System allows the ECP to view the eyelid margin through a magnifier, then warm the eyelid tissue to a target range of 40 to 42 °C to melt the meibum blocking the gland orifices and then apply compression to the eyelid to express

{4}------------------------------------------------

the melted meibum through the orifices. The inner eyelid temperature and the amount of force applied to the eyelid are both displayed on the Instrument allowing the clinician to titrate the ideal amount of heating and compression to optimize unclogging of the blocked glands.

The Disposable is a sterile, single-use component that is attached to the iLux Instrument. It includes all parts intended to contact the patient's eyelid.

The iLux Instrument is a handheld device that allows the ECP to view, heat, and compress the portion of the eyelid that is in contact with the Disposable. The source of heating is lime-green and infrared optical radiation produced by LEDs in the Instrument. The ilux Instrument is powered by a rechargeable lithium ion battery. The software Level of Concern is Moderate.

Ancillary accessories include the charging stand with AC power supply.

#### Indications for Use

The iLux System is indicated for the application of localized heat and pressure therapy in adult patients with chronic diseases of the eyelids, including meibomian gland dysfunction (MGD), also known as evaporative dry eye.

### Summary of Testing Performed

A program of design verification and validation testing was performed that includes the following:

- . Biocompatibility
- . Sterility and EO Residual
- Packaging Integrity (i.e., Sterile Barrier) ●
- Transportation
- Optical Radiation Safety ●
- . Electromagnetic Compatibility and Electrical Safety
- Stabilitv/Shelf-Life .
- Performance/Functionality/Safety ●
- Software
- Clinical performance ●

Results of the evaluations demonstrate that the iLux System met the safety and performance requirements as it relates to its indication for use.

#### Clinical Study Summary

A clinical study was conducted to verify that the technological differences between the iLux System and the LipiFlow System (i.e., predicate) do not adversely affect safety and effectiveness as it relates to indications for use.

142 subjects (284 eyes) participated in the study, comprised of 101 women and 41 men, ages 19 to 86 years (mean = 54.9 ± 15.3 years). The subjects were randomized for treatment, in a 1:1 ratio into the treatment groups (i.e., iLux, LipiFlow).

The iLux arm of the study met the criteria for non-inferiority relative to the LipiFlow arm for the coprimary effectiveness endpoints - Meibomian Gland Score (MGS) and Tear Break-Up Time (TBUT) and the secondary effectiveness endpoint - Ocular Surface Disease Index (OSDI).

- . MGS improved significantly from baseline in both treatment groups at both week 2 and week 4. MGS improvements did not differ significantly between the two treatment groups at either follow-up visit.

{6}------------------------------------------------

- . TBUT improved significantly from baseline in both treatment groups at both week 2 and week 4. TBUT improvements did not differ significantly between the two treatment groups at either follow-up visit.
- OSDI improved significantly from baseline in both treatment groups at both week 2 and . week 4. OSDI improvements did not differ significantly between the two treatment groups.

There was a total of four device/procedure-related adverse events (AEs) of any type. All AEs were observed in the iLux arm and consisted of: burning sensation without skin findings (n=2), petechial hemorrhage in lower lids (n=1), and transient decrease in BSCVA with findings of superficial punctate keratitis (n=1). All were self-limited, transient, and resolved without sequelae.

The secondary safety endpoints were: 1) discomfort and pain, and 2) changes from baseline for ocular surface staining, Intraocular pressure (IOP), and BSCVA (Best Spectacle Corrected Visual Acuity).

- . Pain scores were significantly lower from the baseline for both treatment groups, immediately post-treatment, and at day 1, week 2 and week 4. Immediately posttreatment, the mean pain score was significantly lower for the LipiFlow arm than for the iLux. Pain scores did not differ significantly between the two treatment groups at day 1, week 2, or week 4.
- . Discomfort scores were significantly lower from the baseline for both treatment groups, immediately post-treatment, and at day 1, week 2 and week 4. Immediately posttreatment, the mean discomfort score was significantly lower for the LipiFlow arm than for the iLux. Improvements in discomfort scores did not differ significantly between the two treatment groups at day 1 or week 2. At week 4, however, the discomfort score was significantly lower for the iLux group.
- Ocular surface staining was significantly increased immediately following treatment in both . treatment groups. At day 1, week 2, and week 4, the ocular surface staining significantly reduced relative to baseline in both treatment groups however did not differ significantly between the two treatment groups.
- . No clinically significant changes in IOP were observed immediately post-treatment or throughout follow-up in either treatment group.
- BSCVA was significantly reduced relative to baseline immediately post-treatment in both . treatment groups but not to a clinically meaningful level. At week 2 and week 4, BSCVA was significantly improved relative to baseline in both treatment groups, but the change was not different between treatment groups.

### Conclusions Drawn from Nonclinical & Clinical Evaluation

The results of the evaluation demonstrate that the iLux System is substantially equivalent to the LipiFlow Thermal System as it pertains to the indications for use and device performance.
