Indications for Use
Labtician Lid Load External Eyelid Sizing Weights are used by the physician to determine the correct gold eyelid weight to be implanted in the treatment of lagophthalmos. Labtician Lid Load External Eyelid Sizing Weights are used by the physician who affixes a succession of external eyelid weights to the outer surface of the eyelid using until the proper eyelid closure is attained. Because the levator muscle seems to strengthen after the weight is added, the optimal weight for implantation is ususally that which holds lid about 1.0 mm lower than the normal lid as the patient looks straight ahead. The corresponding implantable gold eyelid weight is then prescribed for implantation. Sizing weights are not designed to be implanted, and are provided nonsterile and are re-usable following cleaning with soap and water and/or alcohol and rinsing with tap water.
Device Story
Device consists of set of 12 tantalum strips (0.6g to 2.8g) used to determine optimal gold eyelid implant weight for lagophthalmos treatment. Physician manually affixes weights to patient's upper eyelid using adhesive tape; assesses closure until optimal weight identified (typically holding lid 1.0 mm lower than normal). Device is non-sterile, reusable, and cleaned with soap/water or alcohol. Benefits patient by ensuring correct sizing for subsequent surgical implantation of gold weight, facilitating gravity-assisted eyelid closure.
Clinical Evidence
No clinical data provided; substantial equivalence based on identical design, materials, and intended use to the predicate device.
Technological Characteristics
Material: 99.5% pure tantalum. Form factor: Rectangular strips with 12.7 mm spherical radius of curvature. Dimensions: 12 sizes (0.6g to 2.8g in 0.2g increments). Non-sterile. Reusable.
Indications for Use
Indicated for patients with lagophthalmos to determine the appropriate weight of a gold eyelid implant. Used by physicians to assess eyelid closure and prescribe the correct implant size.
Regulatory Classification
Identification
An eyelid weight is a prescription device made of gold, tantalum, platinum, iridium, or surgical grade stainless steel that is rectangular in shape and contoured to the shape of the eye. The device is intended for the gravity assisted treatment of lagophthalmos (incomplete eyelid closure).(1) The external eyelid weight is adhered to the outer skin of the upper eyelid. (2) The implantable eyelid weight is implanted into the upper eyelid.
Special Controls
*Classification.* (1) Class II (special controls) for the external eyelid weight. The external eyelid weight is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 886.9. The special controls for the external eyelid weight are:(i) Testing demonstrating the biocompatibility of the device; and (ii) Labeling must include the following information: (A) Specific instructions regarding the proper placement, sizing, and removal of the device; and (B) A warning stating that the patient should be instructed to remove the device prior to entering a magnetic resonance environment. (2) Class II (special controls) for the implantable eyelid weight. The special controls for the implantable eyelid weight are: (i) Testing demonstrating the biocompatibility of the device; (ii) Testing demonstrating the sterility and shelf life of the device; (iii) Nonclinical testing evaluating the compatibility of the device in a magnetic resonance environment. (iv) Patient labeling to convey information regarding the safety and compatibility of the device in a magnetic resonance environment, the conditions under which a patient with the device can be safely scanned, and a mechanism for a healthcare provider to obtain detailed information about magnetic resonance safety and compatibility if needed.
