Short answer
Most people see better within a few days of cataract surgery, but full healing usually takes about 4 to 6 weeks. During that time eye drops are typically used for around 4 weeks, and some activities such as swimming, heavy lifting and rubbing the eye are avoided. How quickly someone recovers depends on whether the operation was straightforward and on other eye conditions, which can also limit how much vision improves.
Key points
- Most people go home the same day, but should not drive themselves.
- Vision is often blurry for a few hours and improves over several days.
- Full healing takes about 4 to 6 weeks; eye drops usually last about 4 weeks.
- A sight test for new glasses is advised about 4 weeks after uncomplicated surgery.
- Driving should wait until vision is back to normal.
A typical recovery timeline
| Time after surgery | What usually happens |
|---|---|
| First few hours | Vision may be blurry because of the drops used to widen the pupil; most people go home the same day1 |
| First few days | The eye may ache and you may feel tired; a plastic shield may be worn at night1. Most people see better within a few days2 |
| About 4 weeks | Eye drops usually finish1; a sight test with an optometrist is advised4 |
| About 4 to 6 weeks | Full healing is usually complete2 |
In England, NICE advises against routine in-person reviews on the day after uncomplicated cataract surgery3, so many people are not seen again until later, and are instead given information about drops, expected changes in vision and who to contact with concerns3.
What to avoid while the eye heals
- Rubbing or pressing on the eye2.
- Getting water or soap in the eye; swimming, even with goggles12.
- Heavy lifting and sport1.
- Eye make-up1.
- Driving until your vision is back to normal1.
The exact timing for exercise, driving and other activities should come from the operating team, because it depends on how the operation went2. For the same operation performed as a refractive lens exchange, the Royal College of Ophthalmologists suggests avoiding swimming for a week and contact sports for a month, with non-contact exercise often possible from the first day5.
Glasses after surgery
Even after successful surgery, glasses may still be needed for reading or distance, and the prescription is likely to have changed1. The College of Optometrists advises a routine sight test about four weeks after uncomplicated surgery4, which is when new glasses are usually prescribed.
If both eyes need surgery
When both eyes have cataracts, they are usually treated on separate days1. NICE recommends offering second-eye surgery using the same criteria as for the first eye3. Some services also offer surgery on both eyes on the same day, known as immediate sequential bilateral cataract surgery4. The result in the first eye can help guide the lens choice for the second4.
What can slow recovery or limit the result
Serious complications are rare1, but recognised ones include infection, bleeding, ongoing swelling or inflammation, retinal swelling or detachment, and the new lens moving out of position12. These can lengthen recovery.
Cataract surgery also cannot restore sight lost to other conditions such as macular degeneration, glaucoma or diabetic retinopathy2, so the final result depends on the health of the rest of the eye. Months or years later, vision can become cloudy again because of posterior capsule opacification, which is treatable1; see why vision can become cloudy again after cataract surgery.
When to seek medical advice
The NHS advises calling 111 urgently for sudden new floaters or more of them, flashes of light, a dark curtain or shadow across your vision, or sudden blurring, as these may signal a detached retina. See an optician or the eye unit for cloudy or blurry vision, difficulty focusing, a red or painful eye, light or dark patches in your vision, or discomfort with bright light1.
Common questions
How soon can I drive after cataract surgery?
Not until your vision is back to normal, and never on the day of surgery1; your eye team will advise when it is safe2.
Is it normal for the eye to ache?
Yes, some aching for a few days is expected1, but pain that does not ease with over-the-counter painkillers is listed as a possible complication2.
When can I get new glasses?
A sight test is advised about four weeks after uncomplicated surgery4.
How long will I need eye drops?
Usually about 4 weeks, following the schedule your team gives you1.
Bottom line
Day-to-day vision usually improves within days, but the eye needs about a month to six weeks to heal fully and settle for new glasses. Knowing the urgent warning signs matters more than the exact timetable, because prompt treatment of a rare complication protects the result.
