The following is a typical list of practical reasons for upper eyelid surgery.
Functional eyelid surgery includes:
There are also other functional eyelid problems such as floppy eyelid syndrome where the eyelids are in a good position about the globe, but are very lax and do not function well. Such patients often have irritation, discomfort and watering.
Facial palsy is another indication for functional eyelid surgery. In facial paralysis, there can be
The correction of eyelid malpositions is part of functional surgery because the eyelids are crucial to the protection of the eyes and any abnormality of their contour, their strength or position, can dramatically affect ocular comfort and vision.
In particular, ptosis is a condition where the upper eyelids droop most commonly in an adult from thinning of the aponeurosis, which is the very delicate front part of the levator muscle which helps to lift the eyelid. Ptosis can also be congenital or have a neurological cause.
Dermatochalasis is where there is excess upper eyelid drooping from excess skin muscle and possibly fat and requires an eye lift called blepharoplasty. Both ptosis and dermatochalasis can interfere with peripheral vision and make it difficult to read or safely drive a car and hence we can demonstrate that there is a useful indication for eyelid surgery.
Entropion or turning in of the lower lid often associate with trichiasis, which is quite painful. That is because the eyelashes are rotating in towards the eyeball and rub on the surface of the eye particularly the very sensitive cornea and can cause redness, watering, irritation, corneal ulcer (keratitis) and requires surgery under local anaesthetic as an outpatient or day case.
Ectropion is where the eyelid is sagging away from the eye and also can cause a red watering irritated the sore eye. All these common forms of eyelid malposition can be corrected by the oculoplastic surgeon, Jane Olver at Clinica London, as an outpatient or day case surgical procedure.
