Can a Plastic Surgeon Lift Your Lower Eye Lid Up to Hide the White Under Your Iris?

Without a picture and a better history it's impossible to give specific recommendations. In general, scleral show created by the lid malposition can be corrected by lower eyelid surgery. A full workup of the orbit would be indicated prior to proceeding.

Hi Hoping, I agree with the discussions below. It doesn't sound like you have had eyelid surgery so it is likely that you have scleral show. I would ask if there has always been a difference between both eyes or if this is something that has come up recently? There may also be some issues in the face below the orbits, (the area that includes the eye/globe and the bony and soft tissue structures that surround this. I would see an experienced plastic or fellowship trained oculo-plastic surgeon for an evaluation. It is important to diagnose the cause of your problem to prescribe the proper treatment. You may need further medical workup. It is impossible to recommend anything without an evaluation. 

As with any condition, diagnosing the cause must come first.  If someone has had previous surgery that may be the cause and lifting the eyelid might be the solution.  If one eyelid has increased scleral show (the white part) and never had surgery, other causes must be considered such as thyroid disease, tumor, facial paralysis etc.  A consultation with an ophthalmologist and preferably an occuloplastic surgeon is a good idea.  Once the cause has been considered appropriate intervention can be pursued.
