Clinical Trial Summary

This clinical trial will evaluate two non-surgical devices designed to improve eye lid opening for patients with severe Blepharoptosis (incomplete opening of the eyelids).


Description:

Two non-surgical devices for patients with Blepharoptosis will be evaluated. The Magnetic Levator Prosthesis (MLP), is an external device that makes use of a newer class of permanent magnets (made of alloys of neodymium (Nd), iron (Fe) and boron (B)) to restore eyelid movement. The Kinesiotape Frontalis Sling (KTFS), involves the use of tape to help facilitate levator muscle contraction to open the eyelid. Video recordings of spontaneous and volitional blinks will be used to evaluate the effects of each device on eyelid reanimation. The clinical trial will employ a crossover design in which participants will try each device at home in counterbalanced order with a washout period between. In each period of the crossover, participants will receive training (during study visits at Massachusetts Eye and Ear) in how to apply the device and will then try the device at home for one week with daily follow up by video calls. At the end of the one-week period of home use there will be a study visit at Massachusetts Eye and Ear when the device will be returned and additional video recordings of eye blinks will be made. At the end of the crossover period, participants will be asked to complete a questionnaire comparing the two devices and to select their preferred device. If considered clinically appropriate, participants may be invited to continue using the preferred device for an additional two months with weekly follow ups to provide information about longer-term use of the intervention. Participants who are still using one of the devices at the end of the two months will be returned to clinical care and receive a study follow up (telephone call) after another 6 and 12 months.

Hypothyroidism that is controlled on medication is allowed

Intervention

Device:
Magnetic Levator Prosthesis (MLP)
Neodymium magnet embedded in a glasses frame and a polymer embedded (PDMS) micro-magnet array fitted externally to the upper lid with IV 3000 securement film. The IV 3000 is FDA approved for extended wear on the skin.
Kinesiotape Frontalis Sling (KTFS)
Kineso Tape is FDA registered as a 510K exempt class 1 device, typically used by physical and occupational therapist to support muscular healing and movement. It is sometimes used on the face in cases of facial palsy or on the eye lid to support the lid in cases of severe blepharoptosis. In such cases it may be attached near the lid margin above the lashes extending up to the forehead skin overlying the frontalis muscle. Alternatively it may be a very short piece attached only along the lid skin. The tape is easily removed.

Outcome

Type Measure Description Time frame Safety issue
Primary Difference between MLP and KTFS in the change in interpalpebral fissure during opening and spontaneous blinking Measurements of the interpalpebral fissure will be taken from video recordings of eye lid opening and closing when using each of the devices Evaluated at baseline and then after being fitted with each device (immediately after, 20 minutes after and 1 week after)
Secondary Difference between MLP and KTFS in the changes in interpalpebral fissure during volitional blinking Measurements of the interpalpebral fissure will be taken from video recordings of volitional eye lid closing when using each of the devices Evaluated at baseline and then after being fitted with each device (immediately after, 20 minutes after and 1 week after)
Secondary Proportion of subjects selecting each device Proportion of subjects selecting either the MLP, the KTFS or neither At the end of the one-week period of home use of the second device
