Do I need eye drops for a physical examination to check intraocular pressure?

Physical examination for intraocular pressure usually requires eye drops, but the specific method depends on the examination. The commonly used methods for intraocular pressure examination include non-contact tonometer and contact tonometer. The former does not require eye drops, while the latter requires the use of surface anesthetic eye drops for examination.

Non contact intraocular pressure examination measures intraocular pressure through airflow, without direct contact with the eyeball. The examination process is fast and non-invasive, and does not require the use of eye drops. Contact type intraocular pressure examination, such as Goldmann tonometer, requires the probe to be lightly touched on the corneal surface. Prior to the examination, surface anesthetic eye drops, such as Obukin hydrochloride eye drops, should be dropped to alleviate discomfort. Some special examinations such as dynamic contour tonometer may also require the assistance of fluorescein staining for observation. If anesthesia solution is used after examination, there may be temporary blurred vision or foreign body sensation, which usually resolves on its own within 30 minutes. Avoid rubbing your eyes.

It is recommended to inform the doctor before the examination whether there is a history of eye medication allergies or glaucoma, and those who wear contact lenses should remove them in advance. After the examination, avoid driving immediately or engaging in fine eye movements, and follow the doctor's advice to use artificial tears to relieve dryness. If there is persistent redness or pain in the eyes, seek medical attention promptly.
