Yes, it is normal that blepharoplasty makes eyes watery. Although watery eye is not severe eye problem, yet it is quite annoying at work or at school. There are some steps you could take to help relieve the syndrome. 1. Place a humidifier in your room to add moist in air. Eyes are exposed to air so the dry air makes eyes dry too. 2. Apply some ointment to lubricate your incisions and eyes. 3. Instill some eye drops which could help wash out any irritants, and lubricate eyes. 4. Apply some warm compress on eyes. The warmth could help glands in eyelids to produce tear film to lubricate eyeballs, and use the warm saline water to wash eyes. 5. Avoid rubbing eyes. 6. Wear sunglasses if you need to go outside if any strong light or glare or sunrays. Blepharoplasty is a very common and popular surgery either functional or cosmetic.
