Will buried sutures used in DST double eyelid procedure cause irritation to the cornea?

The sutures are buried permanently with the knots being placed under the skin surface as opposed to the conjunctiva. However, there is a small risk that the suture can break into the cornea (although I have never personally had this problem). So there is a small but real risk. You will know you have the problem primarily by the sensation of sand in your eyes, sensitivity to light, tearing. You need immediate medical attention if this were to happen.

technically this is a risk and the sutures can extrude towards the cornea through the conjunctiva.  However this fairly rare and I have never seen in my own practice.  if this were to occur and you would simply have to have the sutures removed.  Typically surgeons performing this technique will have the knots facing the skin side or external aspect of the eyelids.  Damage to the eye in general is technically a risk although I don't think this happens very often.  It never happened in my practice and I haven't seen it in any one else's practice.Chase Lay, MD

Usually patients do not experience damage to the eye from the sutures but if they do become irritating, patients will experience the feeling of sand and tearing.  Please consult with a board certified specialist who can assist you with achieving the results you seek.
