After cataract surgery, the period that needs the closest care is the first 2–4 weeks, or longer if the eye doctor says so. The family has four main jobs: give every eye drop on time, fit the hard plastic eye shield whenever your parent sleeps, keep water, dust and smoke out of the eye and stop them rubbing it, and make sure they do not bend their head low or lift anything heavy. No driving for at least one week; after that, the doctor decides. This guide is general advice to help families prepare, but always follow your parent's ophthalmologist first, because each person gets different medicines and restrictions.
Many families describe the same scene. Surgery day passes faster than expected, and back home there are two or three bottles of eye drops, a prescription in tiny print, and a mother who says, "Don't worry, I can do my own drops," though one eye is still blurry. A few days later she forgets the midday round, bends to pick up a laundry basin, or rubs a scratchy eye on waking. These small things are exactly where children can help most. This guide covers questions to ask before leaving hospital, what each stage looks like, how to give eye drops, a fridge-door schedule, the restrictions and how to make them work, warning signs, and preparing for the follow-up visit.
Quick answer
- The period that needs most care is the first 2–4 weeks after surgery, or longer if the eye doctor says so
- Give every drop on schedule, wash hands first, never let the bottle tip touch the eye, leave at least 5 minutes between different drops, and use any ointment last
- Fit the hard plastic eye shield every time your parent sleeps, and do not let them sleep on the operated side
- No rubbing; no water, dust or smoke in the eye; no bending the head below the waist for long; no heavy lifting; take care with hard coughing, sneezing and constipation
- No driving for at least one week; after that, the eye doctor decides
- Worsening vision, increasing pain, a red eye, flashes of light or a dark curtain-like shadow mean going back to the doctor immediately, without waiting for the appointment
1. Why the first week after cataract surgery matters most
The first week is when the newly operated eye needs the most protection, and when your parent is still learning the new rules. Most slip-ups, such as missed drops, the wrong bottle, an absent-minded rub or water in the eye, happen now.
Many parents feel well and want to get straight back to watering plants, sweeping and cooking. The family can help by setting up the home so they do not need to bend or lift, and by having someone remind them about drops until it becomes a habit.
Questions to ask the eye doctor before going home
Write the answers on the same sheet as the drop schedule; the surgeon's advice is what you follow.
- How many times a day is each drop used, until when, and when is the first one due?
- Is the eye shield or protective glasses needed during the day too, or only for sleep?
- When can your parent shower, wash their hair and wash their face normally?
- Can their usual medicines, such as blood pressure tablets, diabetes medicine or blood thinners, continue as normal?
- When is the next follow-up appointment?
- Which symptoms mean coming back at once, and which number works out of hours?
2. What care looks like after cataract surgery, stage by stage
Think in three stages: surgery day and the first night, the first week, and weeks 2–4. Most restrictions last throughout the first 2–4 weeks, or as long as the eye doctor specifies.
Surgery day and the first night
- Someone takes your parent home and rides with them; they cannot drive yet
- At home, let them rest; housework can wait
- Start the drops at the time written on the prescription
- Before sleep, fit the hard plastic eye shield; your parent sleeps on their back or on the non-operated side
- Leave a hallway light on at night, because their vision is not yet at its best and one eye may still be covered
The first week
- Give every round of drops and tick the chart each time
- Wipe the face with a well-wrung damp cloth instead of washing it
- Shower from the shoulders down; wash hair only while lying on the back
- No driving
- If there is a follow-up appointment in this period, always attend, even if the eye looks fine
Weeks 2–4
- Most restrictions still apply: shield at night, no rubbing, no bending low for long, no heavy lifting, no strenuous exercise
- Driving only after the eye doctor has assessed your parent
- If the doctor changes how often a drop is used, update the fridge chart the same day
- When the shield can stop, when normal face washing, swimming or hard exercise can resume: ask the eye doctor at the appointment rather than deciding by feel
3. Giving eye drops step by step, safely and into the eye
Four key rules: wash hands every time, never let the bottle tip touch the eye or lashes, leave at least 5 minutes between different drops, and always use any eye ointment last in that round.
- Wash and dry your hands, and your parent's too if they give their own drops.
- Read the label to confirm it is the right bottle for this round and for the operated eye. If it says shake before use, shake it.
- Have your parent sit with their head tilted back against a chair, or lie flat, and look up.
- Place a finger on the cheekbone and gently pull the lower eyelid down to make a small pocket. Never press on the eyeball.
- Hold the bottle above the eye with the tip in the air, touching nothing, and place the prescribed number of drops into the pocket.
- Release the eyelid and ask your parent to close the eye gently for a moment, without squeezing or blinking hard.
- Dab away drops running down the cheek with a clean tissue. Do not rub the eye.
- Close the cap at once and tick the chart. If another bottle is due, wait at least 5 minutes.
- Eye ointment, if prescribed, always comes last.
If your parent's hands shake, their vision is blurred or tilting the head back is hard, do not let them do their own drops in the first week. A bottle tip that touches the eye or lashes can carry germs into an eye that has just been operated on. Let someone at home give the drops, or at least watch every round until you are confident.
Store eye drops as the label says, never share a bottle, and if it will run out before the appointment, contact the hospital in advance.
4. A fridge-door eye drop schedule that prevents missed and double drops
A good schedule answers three questions at a glance: which round is due, which bottle comes first, and whether it has been given. Make it a single sheet on the fridge or by the bed so every helper sees the same information.
To make the schedule easy to read:
- Write "Bottle 1" and "Bottle 2" on the bottles or boxes with a marker, and the medicine names from the labels on the chart
- List the order of bottles in each round as the doctor or pharmacist advised, with ointment always last
- Link rounds to your parent's routine, such as after waking, after lunch and before bed; this is easier to remember than clock times
- Add a daily tick box that whoever gives the drops ticks straight away, and set phone alarms for each round
A sample layout (copy the number of rounds for each bottle from the real prescription; skip any bottle not due in a round):
- After waking: Bottle 1 → wait at least 5 minutes → Bottle 2 → tick
- After lunch: Bottle 1 → wait at least 5 minutes → Bottle 2 → tick
- Before dinner: Bottle 1 → tick
- Before bed: Bottle 1 → wait at least 5 minutes → Bottle 2 → ointment (if any) → eye shield → tick
If a round is missed, do not double up; call the pharmacist or hospital for advice. If your parent already takes several regular medicines, keeping tablets and eye drops in one system reduces confusion; see setting up a medication system for older adults at home.
5. Restrictions after cataract surgery, and how to make them work
The restrictions protect the newly operated eye from germs and knocks: no rubbing; no water, dust or smoke in the eye; no bending the head below the waist for long; no heavy lifting; care with hard coughing, sneezing and constipation; and no strenuous exercise, for the first 2–4 weeks or as the eye doctor directs. Saying "don't" is rarely enough. Set up the home so your parent never needs to do these things.
Water, dust and smoke
- Wipe the face with a well-wrung damp cloth, avoiding the area around the eyes
- Shower from the shoulders down; a hand-held shower head makes the water easier to control
- Wash hair with your parent lying on their back so water runs backwards, with someone else washing and a folded towel along the forehead. For step-by-step hair washing in bed, see how to give a bed bath and wash hair in bed
- Keep your parent away from incense, cigarette and cooking smoke, and dust from sweeping or shaking out bedding
Rubbing and pressure on the eye
- No rubbing, even if the eye itches or feels scratchy. If discomfort is strong, ask the doctor; do not use other drops
- Fit the hard plastic eye shield every time your parent sleeps, including daytime naps
- No sleeping on the operated side; if that is their usual side, place a bolster pillow as a barrier
- Keep their fingernails short and smooth in case a hand drifts to the eye during sleep
Bending, lifting and straining
- No bending the head below the waist for long. Move water glasses, medicines, slippers and towels to between waist and chest height
- Let your parent sit and lift the foot to put on shoes or trousers instead of bending while standing
- No heavy lifting, such as rice bags, water buckets, wet laundry or plant pots; someone else lifts them throughout recovery
- Take care with hard coughing or sneezing, and prevent constipation with vegetables, fruit and water. If it lasts several days, ask a doctor or pharmacist rather than straining
- No strenuous exercise until the doctor allows it
6. Warning signs that mean going back to the doctor now
If your parent has any of these, contact the hospital that did the surgery and see the eye doctor at once, even before the appointment.
- Vision becoming more blurred
- Increasing eye pain
- A red eye
- Discharge, or a sticky, watery eye
- Unable to tolerate light
- Flashes of light
- Many dark floating spots
- A dark shadow covering part of the vision like a curtain
Many older adults do not want to trouble their children and say nothing until symptoms are severe. Ask the same questions every morning and evening, such as "Is your vision as clear as yesterday?", "Is the eye more painful?" and "Does the light hurt?", and note the answers at the bottom of the drop chart. Save the hospital's in-hours and out-of-hours numbers on everyone's phone.
7. Preparing for the follow-up appointment
The follow-up matters as much as surgery day: the doctor checks that the eye is healing as expected and may adjust the drops. Your parent still cannot drive, so plan who will take them in advance.
What to bring:
- Every bottle of drops and ointment
- The ticked chart and the morning and evening symptom notes
- The eye shield
- The appointment card and hospital card
- A list of regular medicines
- Questions from the week, such as when the shield can stop and when driving can restart
Eye clinic visits often involve several steps and long waits. Having someone there throughout means your parent does not walk alone through busy corridors while their vision recovers, and no new instructions are missed. If no one can take time off, see our guide to taking an older adult to hospital appointments.
Mistakes families often make
- Letting your parent do their own drops from day one. Rounds are missed, bottles mixed up or the tip touches the eye. Give the drops for them, or watch every round, in the first week.
- Giving several drops back to back. The second may wash out the first before it works. Wait at least 5 minutes and put ointment last.
- Stopping the drops because the eye looks better. Continue until the doctor says to stop.
- Forgetting the shield at nap time. Your parent may rub or lie on the eye without realising. Keep the shield on the pillow.
- Letting your parent do chores that involve bending or lifting, such as mopping, laundry, watering plants or lifting pots. Hand these jobs to others for the whole 2–4 weeks.
- Waiting for the appointment when something seems wrong. If any sign from section 6 appears, call the hospital and go back at once; you are not bothering anyone.
When to bring in a professional team
If no one is home during the day in the first week, your parent would be alone, several drops have overlapping times, their hands shake or vision is too poor to give their own drops, or you would need several days off for appointments, a professional helper makes recovery smoother. Free options work too: relatives or trusted neighbours can take turns at drop times, as long as the schedule is clear and everyone follows the same steps.
- A daily caregiver (nursing assistant) for the first week gives eye drops on the doctor's schedule, fits the shield before sleep, wipes the face, helps with showering from the shoulders down and hair washing lying down, fetches and lifts things so your parent does not bend, and watches for warning signs. A 12-hour shift is 1,800 baht per day with a three-day minimum, or 12,000 baht per week. See elderly care at home.
- An escort to eye appointments: the caregiver collects your parent at home, stays through the wait, the pharmacy and the doctor's instructions, then brings them home. 1,800 baht for up to 8 hours, then 200 baht per extra hour; transport is charged separately by distance, and medicines, hospital charges and parking fees are not included. See hospital escort and hospital sitter service.
Frequently asked questions
How long do you need to cover the eye after cataract surgery?
Usually the hard plastic shield is worn every time your parent sleeps for the first 2–4 weeks, or as the eye doctor directs. Whether a shield or protective glasses are also needed during the day depends on the operating surgeon's advice.
What should be avoided after cataract surgery?
No rubbing; no water, dust or smoke in the eye; no bending the head below the waist for long; no heavy lifting; no sleeping on the operated side; care with hard coughing, sneezing and constipation; no strenuous exercise; and no driving for at least one week. Most restrictions apply for the first 2–4 weeks, or as the eye doctor directs.
How many days are eye drops needed after cataract surgery?
Only as long as the eye doctor prescribes. Duration and daily frequency differ between people, and the doctor may change them at follow-up. Do not stop early even if the eye looks better, and contact the hospital if drops will run out before the appointment.
How soon can you drive after cataract surgery?
Not for at least one week. After that, the eye doctor decides whether vision is ready for driving. Meanwhile, arrange in advance who will take your parent to appointments.
What should not be eaten after cataract surgery?
In general there are no specific foods to avoid unless the doctor says otherwise. Focus on vegetables, fruit and enough water to prevent constipation, because straining should be avoided during recovery. Parents with other conditions keep to their usual diet; for diabetes, see caring for an older adult with diabetes at home.
Can you wash your hair after cataract surgery?
Yes, but only lying on the back so no water or suds reach the eye. For the first 2–4 weeks, someone else should wash your parent's hair, and showers should be from the shoulders down.
Can you sleep on your side after cataract surgery?
Only on the non-operated side, with the hard plastic shield fitted every time. If your parent tends to roll over, use a bolster pillow as a barrier.
