Post-ptosis Repair and Blepharoplasty - Feels Like There is Something in my Eye

There are a number of possible causes for the feeling you describe, but by far the most likely is dryness of the eye surface.  When a ptosis repair lifts the eyelid up, the ocular surface is more exposed to air, wind, dust, fans, etc. and its not uncommon for eyes to become dry from this.  There are many treatments for this condition, the most likely being lubricating, soothing eye drops, but this should be discussed with your surgeon.  "Calcium deposits" under your eyelid have nothing to do with your condition now, they are incidental. You did not state your age and you included no photographs so I can not comment on your result or why one eye "is not healing as as well as the other eye." You should discuss and review your condition with your surgeon, whom I hope is a board-certified, fellowship-trained Oculofacial Plastic Surgeon with expertise in ptosis surgery.  This is not an easy or simple surgery and it requires a masterful touch.  Best of luck in your recovery.

Many times after eyelid surgery, due to the eyelids being more "open", there is a greater amount of evaporative tear loss leading to dry eye symptoms. I would suggest trying artificial tears 3-4 times per day and lubricating ointment at bedtime to see if there is an improvement. If there is no change, I would suggest seeing your surgeon to ensure there are no retained sutures causing irritation to the eye.
