Post-surgical eye drops are given to reduce the risk of infection and to control inflammation. The duration of drops depends on the complexity of the surgery and whether a patient is receiving a transplant tissue. Antibiotic drops are usually only prescribed for 1 week after surgery. Steroid drops are given for approximately 1-2 weeks after LASIK surgery, 4 weeks after cataract surgery, and for 1+ years after corneal transplant surgery. The steroid regimen will depend on how your body is responding to surgery and may vary between your first and second eye.
