Cataract Surgery: the nurse's role, start to finish
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Cataract surgery nursing management centres on protecting intraocular pressure, not on the eye itself. Confirm the correct eye, hold anticoagulants per surgeon order, position the patient supine and still under local anaesthesia, and after surgery watch for pain, sudden vision loss, or a fixed pupil. Discharge teaching is one message: no bending, no lifting, no straining.
What the procedure achieves
Cataract surgery removes a clouded lens, usually by phacoemulsification, and replaces it with an intraocular lens implant. The clouding happens gradually as lens proteins denature with age, UV exposure, diabetes, or steroid use, and it cannot be reversed with drops or glasses once dense. Surgery is elective in nearly all cases, done under local or topical anaesthesia with light sedation, and takes well under an hour.
The goal is restored visual acuity, not a cure for an eye disease. Patients often have cataracts in both eyes but are staged one eye at a time, several weeks apart, so the second eye is protected while the first heals. Know this staging when you take a history — a patient booked for the left eye may already be functionally one-eyed from an unoperated right cataract, which changes fall risk and how you plan their discharge.
Pre-procedure nursing responsibilities
Confirm the correct eye against the consent form, the surgical booking, and the patient's own statement — wrong-site eye surgery is a sentinel event and the checks exist because it has happened. Verify anticoagulant and antiplatelet status against the surgeon's specific instructions; many cataract procedures proceed on aspirin or even warfarin because the incision is tiny, but this is surgeon-dependent and must never be assumed.
Instil the prescribed dilating and anaesthetic drops on the timed schedule the pre-op order sets out, since a poorly dilated pupil forces the surgeon to work in a smaller field. Screen for uncontrolled cough, restless leg symptoms, or an inability to lie flat and still, because the patient stays awake and immobile under a surgical drape for the duration. Document baseline visual acuity in both eyes before any drops go in.
Equipment and positioning
Position the patient supine, head stabilised, with the operative eye centred under the microscope and the fellow eye covered or shielded to prevent involuntary drift. A pillow or headrest that keeps the neck neutral matters more here than in most procedures, since any head movement during phacoemulsification risks corneal or lens capsule injury.
The room needs the phaco machine, irrigation and aspiration lines, a sterile eye drape with a fenestration for the operative eye, and calibrated topical or sub-Tenon's anaesthesia ready before the patient is draped. Have the intraocular lens power confirmed against pre-op biometry before the case starts — a mismatch here is not correctable once the eye is closed. Keep a call bell or a plan for the patient to signal discomfort, since they remain conscious and cannot nod or speak freely under the drape.
Complications and early signs
Watch for sudden, severe eye pain in recovery — mild grittiness is expected, but sharp pain suggests raised intraocular pressure or endophthalmitis and needs the surgeon told immediately, not charted and left for the next round. Endophthalmitis is rare but sight-threatening; it usually declares itself within one to a few days as increasing pain, redness, and blurred vision rather than in the recovery bay.
A sudden shower of new floaters, a curtain across the visual field, or flashing lights signals retinal detachment or vitreous haemorrhage and is an emergency referral, not a teaching point for later. Posterior capsule rupture during surgery increases the risk of retained lens fragments and postoperative pressure spikes, so a patient flagged intra-operatively needs closer pressure monitoring than a routine case. Persistent nausea or vomiting also raises intraocular pressure and should be treated promptly rather than tolerated.
Post-procedure care
Most patients go home the same day with a clear plastic shield taped over the operative eye, to be worn at all times initially and overnight for about a week to prevent inadvertent rubbing or pressure. Confirm a driver is arranged, since vision in the operative eye will be blurred and pupils remain dilated for several hours.
Teach the prescribed drop sequence precisely — typically a topical antibiotic and a corticosteroid or NSAID, tapered over two to four weeks — and check the patient or a carer can physically instil drops without touching the bottle tip to the eye. Review red-flag symptoms before they leave: worsening pain, sudden vision loss, or increasing redness means calling the surgical team, not waiting for the routine follow-up appointment.
What to teach before discharge
The single message that matters is about pressure, not the eye itself: no bending at the waist, no heavy lifting, and no straining, including at stool. Any of these raises intraocular pressure sharply enough to threaten the surgical wound and the lens implant in the first week or two after surgery, well before it threatens vision through any direct mechanism.
Give this instruction in concrete terms the patient can act on — no lifting anything heavier than a full kettle, bend the knees rather than the back to pick things up, and take a stool softener if constipation is a risk, since straining at the toilet raises pressure just as effectively as lifting does. Reinforce that the eye shield goes back on for sleep and naps until the follow-up visit, avoid swimming and eye makeup for about a week, and confirm the patient has the follow-up appointment, usually within twenty-four to forty-eight hours, before they leave.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our med-surg practice questions are the closest set to what this page covers.
One question from the med-surg set
A client with chronic obstructive pulmonary disease has an oxygen saturation of 88% on 2 L/min via nasal cannula and is alert with no distress. What should the nurse do first?
Rationale
In COPD a saturation of 88–92% is the therapeutic target, not an emergency, and this client is alert with no distress. The first action is the independent nursing intervention that is least invasive and most likely to help: sit them up and reassess. Turning the oxygen up to 6 L/min risks blunting the hypoxic drive, and calling rapid response or drawing an ABG escalates ahead of an assessment you have not finished.
Answer: B
Common questions
Can cataract surgery be done on both eyes at once?
Not as routine practice. Eyes are staged separately, usually one to several weeks apart, so if a complication affects one eye the other is unaffected and still functional.
How long does the eye shield need to stay on?
Worn continuously for the first day, then during sleep and naps for about a week, mainly to stop the patient rubbing the eye or pressing on it while unconscious.
What intraocular pressure symptoms should trigger an urgent call?
Sharp or worsening eye pain, sudden blurring beyond the expected post-op haze, nausea and vomiting, or halos around lights. These can indicate a pressure spike and should not wait for the scheduled follow-up.
Why is straining at stool relevant to eye surgery?
The Valsalva manoeuvre involved in straining raises intraocular pressure in the same way bending or lifting does, which can threaten a fresh surgical wound and the lens implant position.
Can the patient resume anticoagulants right after surgery?
Follow the surgeon's specific order — many patients are kept on aspirin or warfarin throughout because the phacoemulsification incision is self-sealing and small, but this decision is surgeon- and case-specific.
