Patient: I used the computer too much during the summer vacation, and when school started, I only felt a little dryness, so I didn’t pay much attention to it. When I went to the hospital, I found that the tear film rupture time was short and the tear secretion was insufficient. I went to many hospitals, but nothing helped, I was only told to order some artificial tears, which is not a cure. Now I have dryness and soreness from time to time. It has been two months since the onset of the disease and it is very painful! The artificial tears are not effective, but after a while, it is still dry. Can I get rid of dry eyes? What other treatments are available? The results of laboratory tests and examinations: eye pressure is normal, tear test: these times respectively, left 6, right 3; left and right are up to standard; left 15, right 4; left up to standard, right 4. Tear film rupture time: left 4 seconds, right 5 seconds; left 6 seconds, right 6 seconds. Qiao Ronghua, Ophthalmology Department, Peking University First Hospital: 1, if you have myopia, please wear glasses (need dilated pupil examination); 2, use the computer less, if used, time control within 1 hour; 3, use as little medicine as possible, to use, try to use the preservative-free.
