Lagophthalmos, or inability to completely close one's eyelids, is always a risk in any brow lift or eye lid surgery. In your case, it is a risk that must be considered very seriously by you and your surgeon. Thorough preoperative evaluation and planning, along with meticulous surgical technique, can make for a successful surgery. Patients with dry eyes can have brow lift surgery, but your surgeon should be more conservative when judging how much to lift your brow to still allow for adequate eyelid closure.Alternatively, you could also explore non-surgical options such as a chemical brow-lift with Botox. However, the elevation may not be to your satisfaction but considering the risks, this may be a good option. Hope this helps and best of luck, Dr. Chung
