1. An instrument for isolating a candidate eyelash from adjacent eyelashes to attach a prosthesis to the candidate eyelash, the instrument comprising:
a handle having an asymmetric geometry with respect to a transverse plane of the handle;
an instrument tip having a rigid outer perimeter and a tip aperture within the rigid outer perimeter, the tip aperture including a distal slot having a slot width configured to receive the candidate eyelash;
eyelash deflectors of the instrument tip configured to deflect the adjacent eyelashes away from the candidate eyelash as the instrument tip is advanced relative to the candidate eyelash, the distal slot having a slot length that extends past the eyelash deflectors;
a maximum outer diameter of the instrument tip configured to provide an upper bound on an amount of deflection of the adjacent eyelashes; and
a prostheses repository including at least one prosthesis, the prostheses repository disposed between the handle and the instrument tip.
 
11. A method for attaching a prosthesis to a candidate eyelash, the method comprising:
deflecting eyelashes adjacent to the candidate eyelash by distal deflectors of an instrument tip of an instrument;
actuating the candidate eyelash into a distal slot of a tip aperture of the instrument tip, the instrument tip having a rigid outer perimeter defining the tip aperture;
advancing the instrument tip relative to the candidate eyelash;
deflecting the eyelashes adjacent to the candidate eyelash by eyelash deflectors of the instrument tip;
disposing the candidate eyelash in an open area of the tip aperture, a first portion of the rigid outer perimeter defining the distal slot of the tip aperture and a second portion of the rigid outer perimeter defining the open area of the tip aperture, the distal slot having a slot length that extends past the eyelash deflectors; and
attaching the prosthesis to the candidate eyelash while the candidate eyelash is disposed in the open area of the tip aperture.
 
18. An instrument for isolating a candidate eyelash from adjacent eyelashes, the instrument comprising:
a handle having a handle distal end and a handle proximal end;
an instrument tip having a rigid outer perimeter and a tip aperture within the rigid outer perimeter, the tip aperture including a distal slot having a slot width configured to receive the candidate eyelash, the rigid outer perimeter configured to apply a force to the adjacent eyelashes;
distal deflectors of the instrument tip configured to deflect the adjacent eyelashes away from the candidate eyelash if the adjacent eyelashes are separated by a distance that is less than a width of a portion of the instrument tip that encloses the distal slot;
a prostheses repository including first prosthesis strip having a first prosthesis and a second prosthesis strip having a second prosthesis, the first prosthesis having a first length and the second prosthesis having a second length; and
an adhesive reservoir disposed between the instrument tip and the prostheses repository, the adhesive reservoir configured to house an adhesive.
