When can I read and use screens after trabeculectomy?

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

The Glaucoma Research Foundation advises taking a break from reading early on. Screens do not damage the eye, but blurry vision limits comfort for weeks.

The Glaucoma Research Foundation lists reading among the things to take a break from while recovering from incisional glaucoma surgery, alongside driving, bending, and strenuous exercise. That advice is about the early recovery period, not forever.

Screens and books do not harm a healing trabeculectomy the way bending and straining can. What limits you is vision. The American Academy of Ophthalmology says vision may be blurry for several weeks after trabeculectomy, and the Glaucoma Research Foundation describes blurred vision for about six weeks before it usually returns to its previous level.

Two practical points. Sustained near work makes any eye feel dry and tired, which is worse when you are also on frequent drops, so take breaks and blink. And do not buy new glasses to fix the blur. The American Academy of Ophthalmology says a new prescription is usually measured once the eye has healed, often around 6 to 8 weeks, because the numbers can keep changing before then.

When	Typical guidance
First week	GRF advises taking a break from reading during early recovery.
Weeks 2 to 6	Read and use screens as comfort allows. Vision is often still blurry per AAO and GRF.
6 to 8 weeks	AAO says a new eyeglass prescription is usually measured once the eye has healed, often at 6 to 8 weeks.

Call your surgeon now if you notice any of these

A red, painful eye with discharge, especially with light sensitivity or a white spot on the bleb. The American Academy of Ophthalmology says to contact your doctor immediately for a red, painful eye, and EyeWiki lists sudden pain, photophobia, discharge, and conjunctival redness as features of bleb associated infection. This rule is for life, not just the first weeks, because EyeWiki classifies bleb infections as early onset within one month or late onset after one month.
Any sudden decrease or loss of vision, at any time after surgery
New flashes of light, a sudden shower of new floaters, or a curtain or shadow across your vision
Pain that is getting worse instead of better, or pain not relieved by your prescribed drops
A steady trickle of clear watery fluid from the eye, or a sudden change in how the bleb looks, which can signal a bleb leak. EyeWiki reports that bleb leakage increases the risk of bleb infection about 26 fold.
Vision that becomes markedly worse along with a soft feeling eye or wavy, distorted central vision, which can signal very low eye pressure
Thick, colored, or sticky discharge, or the eyelids sticking shut
Any eye that simply does not feel right after glaucoma surgery, which the American Academy of Ophthalmology says can be a sign of infection that must be treated right away

These warning signs after trabeculectomy can point to problems that need same-day care. Do not wait for your next scheduled visit. If you cannot reach your surgeon's office, use their on-call line, or go to an emergency room.
