Eye shield after cataract surgery: duration and fitting

After cataract surgery, the protective eye shield is worn until the evening of the operation, then put back on each night for 7 nights, the night of the operation included. It is held in place with two strips of tape, one on each side, leaving the transparent centre clear. Its purpose is to prevent accidental rubbing or pressure during sleep. During the day, the key instruction comes down to one thing: do not touch the operated eye.

KEY POINTS

PURPOSE

What is the eye shield for after cataract surgery?

The role of the eye shield is mechanical: it forms a rigid dome over the eye and keeps a hand, pillow or sheet from pressing on the operated eye. The French national health insurance (Assurance Maladie) describes it in the same way: a shield worn at night so that the eye is protected from possible rubbing ameli.fr.

Cataract surgery is performed through a micro-incision in the cornea, which most often closes without a stitch: in the first few days, it is best to spare the operated eye any pressure. And it is at night that the risk is greatest, since people rub their eyes in their sleep without realising it.

Habits vary from one surgeon to another. A 2023 systematic review notes this variability and reports that patients prefer to keep some protection rather than none Dhoot 2023; an older review had already pointed out that routine use of the shield after uncomplicated surgery was debated Shoss 2013. There is therefore no universal rule: the instruction to follow is your surgeon’s.

WHAT IT LOOKS LIKE

What does a protective eye shield look like?

Many patients look for a photo before the operation, to know what to expect. The shield fits in the palm of the hand. It is a piece of transparent plastic, teardrop-shaped: rounded at one end, narrower at the other, to follow the contour of the eye socket. Its rim is flat, and it is the rim that rests on the bone. The centre is domed, hollow, and pierced with small ventilation holes.

Two details matter for what follows. It lets you see, which means you can get up at night without taking it off. And it does not touch the eyelid: all the support is carried by the rim, on the eyebrow above and on the cheekbone below. It is neither an occlusive eye pad, which blocks vision, nor a sleep mask, which weighs on the eyelids.

It is handed to you at the clinic, already in place, on the day of the operation, and the same shield is used all week.

DURATION

How long should the eye shield be worn?

For Dr Tourabaly’s patients, operated on at the Clinique Sainte-Geneviève (Paris, 14th arrondissement), the instruction comes in two stages:

  • On the day of the operation: the shield fitted at the clinic stays in place until the evening. It is taken off to put in the eye drops, which start in the afternoon according to the prescription, and then put back on;
  • The 7 nights, including the night of the operation: the shield is put on at bedtime and taken off on waking.

This period may be adapted to your case at the check-up two days after surgery, at the practice, in Cachan or in Paris. The rest of the schedule, eye drops, check-ups and return to activities, is on the page recovery after cataract surgery.

FITTING

How do you fit the eye shield, step by step?

  1. Wash your hands and dry them. Put in your evening eye drops before fitting the shield, never once it is in place. Prepare two strips of microporous tape of the Micropore type, about five centimetres long.
  2. Place the shield over the closed eye, domed side facing outwards. Its flat rim should rest on the bone: the brow above, the cheekbone below. Nothing should touch the eyelid or the lashes. No pad is needed underneath, unless instructed otherwise.
  3. Stick a strip of tape on each side: one on the temple side, the other on the nose side. Each strip goes across the rim, half on the shield, half on clean, dry skin. The transparent centre stays clear.

A properly fitted shield does not move when you turn your head and transmits no pressure to the eye: if you feel pressure on the eyelid, peel it off and start again. Never put a strip across the centre: the shield is transparent so that you can see through it when you get up at night, and a strip placed across it takes that away.

After cataract surgery: fitting the eye shield

The shield stops you rubbing or pressing on the eye while you sleep. Wash your hands before handling it.

On waking, peel the tape off gently, holding the skin with your other hand. Use fresh strips each time you fit the shield; if the skin goes red, move them to a different spot and ask at the pharmacy for hypoallergenic tape.

CARE AND SLEEP

Looking after the shield, and how to sleep?

Keep the shield clean and store it away from dust between nights. A cracked shield should be replaced: a chipped edge can hurt the skin. If in doubt, ask the practice for advice.

As a precaution, many patients prefer to sleep on their back or on the side of the non-operated eye for the first few nights, so as not to crush the shield against the pillow; if your surgeon has given you an instruction on position, that takes precedence. Nothing prevents you from getting up at night: the shield stays in place, and you can see through it.

DAYTIME

During the day: glasses or sunglasses?

Once the evening of the operation has passed, the shield is no longer required during the day. When awake, you control your movements: the instruction is not to touch the operated eye. No special protective glasses need to be bought: your usual glasses, or sunglasses, act as a screen against wind, dust and the finger that goes to the eye by reflex, and ease the glare of the first few days: see sun and holidays after the operation.

If the eye stings or waters, do not rub it: wipe the cheek, and clean any discharge with sterile gauze and saline solution, never with cotton wool. This sensation of grit under the eyelid is usual in the first few days. The other movements to avoid, such as bending over or lifting heavy objects, are detailed on the page what not to do after cataract surgery.

NORMAL OR NOT

I rubbed my eye or slept without the shield: what should I do?

Don’t panic: a brief rub or a night without the shield most often has no consequences. Do not touch the eye again, carry on with your eye drops, and put the shield back on the following night. What remains is to tell what is expected from what is not.

What is usual in the first few days: stinging and a gritty, sand-in-the-eye feeling, linked to the antiseptic used in the operating theatre; a watering eye; vision that stays blurred or hazy for the first few days.

Seek medical advice without delay if you have: severe pain not relieved by paracetamol; a sudden drop in vision; a red, painful eye; a black curtain, flashes of light or many sudden floaters; thick discharge, eyelids stuck together, fever.

During the day, Monday to Friday: Cachan practice, +33 1 45 47 08 11. In the evening, at night and at weekends: eye emergency departments with no appointment needed, Quinze-Vingts (Paris, 12th arrondissement, 01 40 02 15 20) or the Ophtalmopôle at Cochin (Paris, 14th arrondissement, 01 58 41 27 04). The 15 (the French emergency medical number) is reserved for life-threatening emergencies. Details on the page eye emergencies.

Without any of these signs, a simple doubt justifies a call to the practice: better one question too many. Discomfort that sets in or comes back later also deserves to be assessed: see eye pain one month after the operation.

FREQUENTLY ASKED QUESTIONS

Frequently asked questions

How long should the eye shield be worn after cataract surgery?

For patients operated on by Dr Tourabaly: until the evening of the operation, then at night for 7 nights, the night of the operation included. If you were operated on elsewhere, follow your surgeon’s instruction.

Should the shield be worn during the day?

Only on the day of the operation, until the evening. After that, it is for night-time only; during the day, your glasses act as a screen.

Where should the tape be stuck to hold the shield in place?

Two strips on the sides: one on the temple side, one on the nose side, each straddling the rim, half on the shield, half on the skin. Never a strip across the centre.

Can you see through the shield?

Yes: it is transparent and pierced with small ventilation holes. As long as the centre stays clear, you can get up at night without taking it off.

Which tape should be used to hold the shield in place?

A microporous tape of the Micropore type, in two side strips. If the skin reacts, move them and let the practice know.

My shield is lost or broken: what should I do?

Pharmacies sell protective eye shields. A night without the shield does not require a consultation in the absence of a warning sign.

Do you need to use the shield again for the second eye?

Yes: the second eye, operated on one to two weeks after the first, follows the same instruction: shield until the evening, then 7 nights.
