Is feeling the tube or plate normal after tube shunt surgery?

General information about typical recovery, not medical advice. Every eye and every surgery is different, and your surgeon's instructions override anything on this page. Read our full disclaimer.

Short answer

Some awareness of the device is common, especially early. It should fade, and anything that feels like something poking through needs prompt review.

What's normal

A tube shunt is a real object in your eye, so a sense of fullness, pressure, or a foreign body feeling under the upper outer eyelid is common in the early weeks. BrightFocus Foundation describes the Ahmed valve as shaped like a miniature computer mouse with a tube at the end, which gives a sense of the size sitting behind the eyelid. The American Academy of Ophthalmology describes the device as a soft, flexible tube connected to a small plate.

Surface stitches and the patch graft add to the scratchy feeling early on, and most of that eases as the stitches loosen or dissolve over the first weeks. Many people stop noticing the device entirely, though some remain mildly aware of it long term.

Usually most noticeable in the first 2 to 6 weeks and fading after that. Sharp or worsening sensation is not part of normal healing.

When it stops being normal

A feeling that something sharp is poking, or a spot that stays sore and red over the tube, should be reported promptly. EyeWiki says tube erosion usually results from conjunctival melting near the limbus overlying the tube and needs prompt surgical intervention to prevent endophthalmitis.

Also report it if the American Academy of Ophthalmology red flag applies, which is an eye that is red, painful, or just does not feel right, because that can be a sign of infection needing treatment right away. BrightFocus Foundation notes the implant may sometimes work its way to the surface of the eye and have to be repaired or removed.
