2Planning and surgical preparation

Surgical preparation

Clinical examination is the best way to choose the appropriate eyelid weight.

Different weights are placed on the skin centered over the mid-pupillary line of the patient's upper eyelid and taped in position.

The patient is encouraged to open and close the eyelid.

The amount of closure compared to ptosis is judged and the best weight is selected.

When considering the optimal weight, there is a tradeoff between functional closure and eyelid position and appearance during opening.

If considering lower lid suspension, then upper lid procedures should be considered secondarily. Lower lid procedures can alter the size of upper eyelid weight required.
