Antibiotic eye drops are prescribed to reduce the patient's chances of acquiring an eye infection after LASIK surgery. Any type of surgery, including LASIK, introduces the risk of infection; during surgical procedures, an incision is made in the bodily tissue, making the inner cavity more vulnerable to bacteria. Surgeons typically recommend the use of antibiotics, either in the pill or topical form, after all types of surgery. For LASIK patients, eye drops will sufficiently deliver the antibiotic solution to the healing corneal tissue.
One way that it works is to decrease inflammation (swelling). It does this by preventing infection- fighting white blood cells (polymorphonuclear leukocytes) from traveling to the area of swelling in your body. (This is why you are more prone to infection while taking steroids). Taking advantage of the anti-inflammatory properties of the medication, corticosteroids are used to decrease the swelling around tumors. For example, by decreasing swelling around tumors in the spine, brain, or bone, it can decrease the pressure of the tumor on nerve endings and relieve pain or other symptoms caused by the pressing tumor.
Ocular adverse reactions occurring in 5%-15% of patients treated with loteprednol etabonate ophthalmic suspension (%-%) in clinical studies included abnormal vision/blurring, burning on instillation, chemosis, discharge, dry eyes, epiphora, foreign body sensation, itching, injection, and photophobia. Other ocular adverse reactions occurring in less than 5% of patients include conjunctivitis, corneal abnormalities, eyelid erythema, keratoconjunctivitis, ocular irritation/pain/discomfort, papillae, and uveitis. Some of these events were similar to the underlying ocular disease being studied.
