Trial Safety

Trial Design

2 Treatment Groups

Experimental Group

This trial requires 30 total participants across 2 different treatment groups

This trial involves 2 different treatments. Magnetic Levator Prosthesis (MLP) is the primary treatment being studied. Participants will all receive the same treatment. There is no placebo group. The treatments being tested are not being studied for commercial purposes.

Experimental Group
The purpose of the experimental group is to test the intervention. Participants will have their acuity measured (refraction as needed), slit lamp with Nafl & NEI scale, visual functioning questionnaire (VFQ), cognitive assessment (MOCA).The eye lid will be prepped and video recorded.The masked clinical staff will then apply the polarized magnets and perform a number of measurements to ascertain effectiveness of intervention. -Intervention - Magnetic Levator Prosthesis (MLP)
ControlNo treatment in the control group

How many people get blepharoptosis a year in the United States?

Add answer

Results from a recent paper of a study from Sweden suggest that 5.9% of men aged 40 to 69 years and 5.3% of women aged 60 and over report having had some amount of blepharoptosis. A high percentage of people with blepharoptosis are dissatisfied with the appearance of their eyes. Further research is required to explore the causal mechanism in blepharoptosis and its potential impact on daily life.

Unverified Answer

What are the signs of blepharoptosis?

Add answer

Signs of blepharoptosis include a drooped eyebrows, thin eyebrows, a lack of the lower eyelashes or alopecia of the eyebrows. Blepharoptosis can range from the mild form to the severe variety.

Unverified Answer

What is blepharoptosis?

Add answer

Blepharoptosis is a disease of facial appearance characterised by the drooping of the lower eyelid and the associated eyelid retraction. A considerable number of adults and children are affected. The pathogenesis of blepharoptosis is unknown. In the study, the eyelid position was compared pre-operatively and post-operatively. Results from a recent paper showed that the severity of the blepharoptosis was reduced after surgery and that the eyelids returned to a normal position. Blepharoptosis is a common disease associated with aging and women are most commonly affected. The use of eye drops for the application of artificial tears or eye ointments post-operatively does not appear to help the condition.

Unverified Answer

Can blepharoptosis be cured?

Add answer

Blepharoconjunctivitis, which is caused by an imbalance in septal cartilage function, is a condition that may result from blepharoplastosis. Treatment of blepharoconjunctivitis involves removal of blepharoplastosis.

Unverified Answer

What are common treatments for blepharoptosis?

Add answer

The most common treatment for blepharoptosis is bimatoprost, which is a synthetic analogue of the naturally occurring PTGF-B. Other solutions may include eye hygiene and massage, taping at the bottom of the eyelid, blepharoplasty, and laser hair removal. summary: This article discusses what is commonly accomplished by physicians and surgeons for the treatment of wrinkles.

Unverified Answer

What causes blepharoptosis?

Add answer

Nerve injuries may cause permanent alterations in the function of nerves controlling the levator palpebrae superioris muscle. The result may be a temporary or permanent one, but the cosmetic impact is normally acceptable.

Unverified Answer

Is magnetic levator prosthesis (mlp) typically used in combination with any other treatments?

Add answer

Patients treated with MLP plus eyelid surgery (blepharoplasty), especially if they have also been treated with other forms of correction, are likely to have improved postoperative eyelid position.

Unverified Answer

Has magnetic levator prosthesis (mlp) proven to be more effective than a placebo?

Add answer

The MLP technique is an effective procedure in treating patients with blepharoptosis. For this procedure, the MLP technique was more effective than a placebo, and was shown to be an effective and safe option in the treatment of blepharoptosis.

Unverified Answer

What are the latest developments in magnetic levator prosthesis (mlp) for therapeutic use?

Add answer

Although early use of a magnetic sleeve with the prosthesis led to improvement in the function of the eyelids in patients with blepharoptosis, this has not been proven in randomized controlled trials. However, in view of the favourable findings in other trials, magnetic prostheses that have become commercially available are an alternative treatment option for blepharoptosis and other eyelid complaints and may be a valuable treatment modality.

Unverified Answer

What are the chances of developing blepharoptosis?

Add answer

Blepharoptosis is rare. A small number of patients are susceptible to develop blepharoptosis. There are no statistical differences between genders and ages for the development of blepharoptosis. However, there may be a correlation between blepharoptosis and diseases. Therefore, there will be more research done on blepharoptosis with larger sample sizes.

Unverified Answer

What is the primary cause of blepharoptosis?

Add answer

There was a higher rate of blepharoptosis in both females (3.25%) and males (3.5%) who had blepharoplasties. The rate of blepharoptosis in these patients was not dependent upon surgical approach (trans-sphenoidal vs. trans-palpebral) or in age (>60 yrs.), but is most likely related to ptosis surgery.

Unverified Answer

What are the common side effects of magnetic levator prosthesis (mlp)?

Add answer

Considering all our patients, [the most common adverse side effects are listed in table (1)] and [MLP is considered a minimally invasive procedure with a very low risk of complications. So in the following days if you have any issues, it is very important to talk to your doctor.
