Ptosis surgery aims to strengthen the little muscle that lifts the upper eyelid. There are a number of different approaches to achieve this. Occasionally if the muscle is too weak, the forehead muscle may be used to help lift the upper eyelid, this is called a frontalis suspension procedure.

Ptosis surgery may be required due to one or more of the following:

• Reduced vision in the affected eye which may result in a lazy (amblyopic) eye
• Excessive drooping of the upper eyelid with or without resultant headaches
• Reduced field of vision, which may result in abnormal head posture
• Unacceptable appearance of eyelid
