Lower eyelash impingement is more common in children, mostly due to the hypertrophy of the orbicularis oculi muscle of the eyelid after birth, accompanied by the medial canthus, which causes the eyelashes to grow inwardly. For children before 3 years of age, the eyelashes are softer and less irritating to the cornea or conjunctiva, so they can be observed at this stage, and then they can do eyelid massage and eyelid pulling, that is, massage and pulling outward and downward every day, and then some of them may recover from the inverted eyelashes automatically, or they can put on the stacked mesh adhesive tapes, which can deflect the direction of the eyelashes away from the cornea. If the eyelashes are harder after the age of 3, it may cause damage to the cornea, in this case, it is recommended to consider children’s implantation surgery, children’s implantation surgery between the ages of 3-10 years old may require general anesthesia, the treatment is generally cosmetic threads, and the removal of the threads generally rarely leave scars, so it is recommended to do the surgical treatment after the age of 3 years old.
