How long cataract patients can be treated with intraocular pressure drops or oral medication after surgery is related to their condition and is not set in stone. Generally, it is 2~3 days, and those with secondary symptoms need to extend the duration of the medication. For cataract patients with transient elevation of intraocular pressure in the early stage after surgical treatment, intraocular pressure-lowering eye drops can usually be ordered to control intraocular pressure, such as carteolol hydrochloride eye drops, brimonidine tartrate eye drops, etc., and oral vinpocetine tablets or acetazolamide tablets can also be taken to reduce intraocular pressure. Medications need to be used as prescribed by the doctor. Generally speaking, when the intraocular pressure drops to normal in about 2~3 days, the medication can be stopped. However, for patients with secondary glaucoma, whose intraocular pressure cannot be lowered to normal for a long time, it may be necessary to use intraocular pressure-lowering drops for a long time to control the intraocular pressure, but it is not suitable for long-term treatment with oral medication, and the specific situation must be reviewed, and the doctor will make a judgment according to the intraocular pressure situation to guide the patient to use the medication reasonably. It is recommended that patients go to the ophthalmology department of a regular hospital for consultation and use the medication under the guidance of the doctor.
