Eyelid surgery to enhance appearance of lower eyelids
You do indeed have scleral show below the inferior limbus of your eye as evidenced on your photographs. Although this is a normal variant, the eyelids can be enhanced by elevating the eyelid margins to reduce the visible "scleral show". The procedure is safe and effective and is usually performed without the need for general anesthesia. Consulting with a board certified Plastic Surgeon or Oculoplastic Surgeon will allow you to decide the best approach for "correction". Good luck with your surgery!
Can lower eyelids be elevated?
You have scleral show as a generically acquired variant. Most of the time scleral show is seen as a consequence of lower Blepharoplasty. This is a very correctable condition by performing a lateral Canthoplasty or a Lateral Tarsal Strip which involves making an incision just below the lash line to the outer corner of the eye and pulling up the outer corner of the eye and fixing it at a higher point this correcting the Scleral show. You should see an experienced Facial Plastic, Plastic or Oculoplastic Surgeon to get an evaluation.
