Trial Design

2Treatment groups
Experimental Treatment
Group I: Experimental GroupExperimental Treatment1 Intervention
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)
Group II: Control/Normal Vision GroupExperimental Treatment1 Intervention
The purpose of the normal vision group is to test the experimental setup prior to enrolling ptosis patients. If the measurements of the normal vision group are found to be non-different to the experimental group, the data will be pooled. -Intervention - Magnetic Levator Prosthesis (MLP)
