Modern cataract surgery is one of the safest of all surgical procedures. Most complications, even if they occur, are not serious. So are dry eyes. Don't be too anxious. After cataract surgery, you should keep using artificial tears, four times a day, to replenish moisture and keep ocular surface moist and to produce solution with viscosity and water absorption covering the ocular surface in order to prolong tear break-up time and improve the discomfort symptom. In your daily life, you should develop a good life habit, such as ensuring ample sleep, taking more fruits containing vitamin A and vitamin C, applying hot compress on your eyes, blinking more, shortening the time that you spend on computer.
