You will use drops for a week; these drops are a combination of an antibiotic and a anti-inflammatory preparation. If you are not asleep, please apply the drops into each eye operated on every 3 hours. When you are asleep, do not let yourself be woken up because of the drops. Restful sleep is more important for the healing process than the drops. Start to apply so-called ""artificial tears"" since after the second post-operative day. They help keep the eye surface in an optimum condition. The frequency and duration of the application of artificial tears as well as the specific product may differ in each of the patients. The doctor will inform you in time of how to use artificial tears.
