As to eye dryness, there are many home remedies that I can share with you. Because dust and wind might make eye dryness worse, so have an air cleaner to filter the dust in your room and put a humidifier to add moist to air which is good for dry eyes. When you need to go outside, you'd better wear sunglasses to avoid damages from sunrays, winds or dust. After your operation, the surgeon might prescribe some eye drops for you. If it still can't relieve the dryness, you should tell the doctor what your situation is, he/she could prescribe some moisturizing eye drops or you can get some artificial tears over-the-count. Don't prolong the working time for eyes. It needs rather a long time to heal so you should protect them as much as you can. The prolonged working time might cause eye strain, eye dryness, blurry vision and even headache. When you have time in weekends, you can try some lukewarm compress of saline solution. Apply the compress for less than 20 minutes each time, 3-4 times per day. Good luck!
