Cataract surgery in Limerick

What is a cataract?

Which symptoms can cataract cause?

Blur, glare, difficulty with night vision, faded colours and changing spectacle needs can occur with cataract. These symptoms are not specific to cataract, so a symptom checklist cannot establish the diagnosis. Describe whether the change is gradual or sudden, whether it affects one or both eyes, and which situations make it most noticeable. [14]

Why does the lens become cloudy?

Ageing is the most common setting for adult cataract. Previous eye injury, inflammation and exposure to certain medicines, including corticosteroids, can also be relevant. Tell your consultant about previous operations, laser treatment and steroid tablets, injections, inhalers or drops. A medicine history helps assessment; it is not a reason to stop a prescribed treatment yourself. [1][14]

Type 2 diabetes is associated with an increased risk of cataract. Diabetes can also affect the retina, so a cloudy lens may not be the only explanation for blur. If you have diabetes, bring details of your eye screening and any previous retinal treatment. Your assessment covers how these findings affect the plan. [8][9]

Smoking is associated with age-related cataract. Your assessment also considers previous eye treatment and medicines. Bring a complete list, including steroid tablets, inhalers and eye drops; do not stop prescribed medicines without advice. [1]

How is cataract assessed?

Clinical assessment helps establish whether cataract explains the symptoms and whether another eye condition may affect the result. This guide describes general diagnostic methods, not a fixed package of tests at your first consultation. Bring your glasses, a list of your medicines and any previous letters or reports. [1]

If surgery is being considered, optical biometry measures the eye to help calculate implant power. Corneal measurements help assess astigmatism. Measurements support a calculation rather than a guarantee of a particular spectacle prescription. Tell the team about contact lenses and previous laser vision correction, because these details can change how measurements are planned and interpreted. [1]

Macular OCT provides cross-sectional images of the central retina. A systematic review supports its role in identifying macular findings that may be missed on examination before cataract surgery. It is an additional investigation, not a substitute for the consultation, and your consultant will discuss whether it is appropriate for your eye. [5]

Monitoring or surgery: how do we decide?

Surgery is considered when cataract interferes with everyday activities and the expected benefit outweighs the risks. NICE bases referral on visual difficulties, quality of life and the person’s preferences, rather than a visual-acuity threshold alone. Bring examples of the tasks you would like to improve. [1]

When the impact is manageable, an updated spectacle prescription or changes to lighting may help with everyday tasks while the cataract is monitored. These measures do not remove the cloudy lens. Ask what change should bring you back sooner and agree how follow-up will be arranged rather than assuming that waiting means no further assessment. [14]

Cataract surgery removes the cloudy natural lens and places an artificial intraocular lens inside the eye. Other conditions, including glaucoma, macular disease and diabetic retinal disease, can influence the result. Treating the lens does not automatically treat those conditions. Your assessment covers the expected benefit and limitations for the whole eye. [14][8]

The ICO leaflet quotes infective endophthalmitis at approximately 0.02–0.16%, equivalent to about 2–16 cases per 10,000 operations. This is infection inside the eye and requires urgent treatment. These population figures provide context; your personal risk also depends on eye health, surgical complexity and preventive measures. [14]

Alshammari’s 2024 meta-analysis estimated retinal detachment at 0.66 per 100 patients, approximately 0.66% or 7 per 1,000; the 95% confidence interval was 0.43–1.00%. It combined studies with different follow-up periods, so this is not a one-year incidence or a prediction for an individual eye. [11]

Other recognised complications include inflammation, swelling at the macula, capsule damage and an unexpected focusing result. Some require additional treatment. Consent should cover both the likely benefit and the complications that matter for your eye, including any existing retinal or optic-nerve disease. [14]

Which lens is right for you?

Our clinic offers monofocal, toric, EDOF and multifocal lens options, chosen according to your eyes, clinical suitability and preferences. Monofocal lenses have one principal focus; toric lenses correct corneal astigmatism. EDOF and multifocal lenses use different optical designs to extend the useful focusing range. Glasses may still be needed. [3]

Multifocal lenses can reduce dependence on glasses, especially for near tasks, but increase the chance of halos and glare compared with monofocal lenses. Cochrane supports explaining both sides of this trade-off. EDOF and multifocal lenses use different designs, and suitability depends on the eye and the visual trade-offs. [3]

What happens on the day?

The surgical procedure itself usually takes about 15–20 minutes; you will be with us for longer for preparation and recovery.

Before surgery, the team checks the correct eye, lens implant, medicines and consent. Bring your medicine list and tell the team about allergies, difficulty lying flat or anxiety. These checks help the surgeon and anaesthetic team prepare the procedure around your needs. [1]

Local anaesthetic numbs the eye using drops, sometimes with anaesthetic placed around the eye. You remain awake and may notice light, movement or water, rather than seeing the operation in detail. Sedation or general anaesthesia is an alternative for selected patients. [14]

Antibiotic given inside the eye during surgery reduces the risk of endophthalmitis. Gower’s Cochrane review found high-certainty evidence for intracameral cefuroxime, with or without topical levofloxacin. This preventive treatment is separate from the drops you may use at home. [7]

How should you plan your recovery?

You will receive a clear written drop schedule; drops are usually used for about three weeks. Follow your individual prescription, as the medicines and duration may vary.

Follow the written schedule supplied with your own bottles. It tells you which medicines to use and when. Ask us if any instruction is unclear; do not change the frequency or stop treatment without advice.

New glasses are usually considered around four to six weeks after surgery, once the eye has settled. The optometrist checks the remaining prescription and whether you need distance, intermediate or reading glasses. The timing can be adjusted if healing is slower or treatment of the second eye is planned. [18]

The HSE/ICO national model describes day-care cataract surgery followed by community review for uncomplicated cases, with earlier hospital review when complications or other eye disease require it. This separates an early clinical check from the later appointment for a settled spectacle prescription. [15]

Dry-eye symptoms can persist during recovery. A systematic review found changes in tear-film measures after cataract surgery, with substantial variation between studies. Report persistent grittiness or fluctuating blur at review so the ocular surface can be assessed and treated. [13]

Posterior capsule opacification is later clouding of the membrane supporting the implant; the ICO leaflet quotes “about 3 in 10” people. The leaflet does not state a follow-up interval. A short laser procedure can treat suitable cases after the cause of renewed blur is confirmed. [14]

For Group 1 car and motorcycle drivers in Ireland, the RSA requires binocular visual acuity of at least 6/12 (0.5), with glasses if needed. The horizontal visual field must reach at least 120°, extending 50° left and right and 20° up and down, without significant central field loss. Glare, contrast and other visual functions also matter; Group 2 standards are higher. [16]
