Cataract surgery removes the eye’s clouded natural lens and almost always replaces it with a clear artificial lens. MedlinePlus describes it as an outpatient procedure, usually done while you are awake with numbing medicine. For an overseas patient the planning centres on three things. These are the measurements for the new lens, the check the day after surgery and whether both eyes will be treated.
What is cataract surgery?
A cataract is a cloudy lens that blocks light so you cannot see clearly. MedlinePlus explains that the surgeon makes a small incision and removes the cataract. The commonest method is phacoemulsification, in which sound waves break the lens into pieces that are suctioned out. Some surgeons use a laser to make the incisions and soften the cataract. An intraocular lens, often shortened to IOL, is then placed in the eye. The incision usually seals itself.
Moorfields Eye Hospital describes cataract surgery as a day-care procedure. The eye is numbed with drops, an injection or both, and sedation is optional. Children usually have general anaesthesia, according to MedlinePlus.
Who may be suitable for it?
MedlinePlus says surgery is usually done when a cataract affects your vision. Because cataracts do not usually cause permanent damage, the timing is a decision for you and your eye doctor. Other eye conditions such as glaucoma or macular degeneration can make surgery more complex. The ophthalmologist who examines you decides whether surgery is right now and which lens suits your eye.
Lens choice is part of the plan
Moorfields notes that a standard monofocal lens can be set for distance vision, so glasses may still be needed for close work. Other lens types exist. Discuss what you want to see clearly without glasses before the measurements are taken.
What tests come before cataract surgery?
MedlinePlus says you will have a complete eye examination with an ophthalmologist, and that ultrasound or a laser scanner measures the eye to choose the lens. Moorfields adds eye tests, a prescription check by an optometrist and a full medical history. Before you travel it helps to send:
- Your latest eye examination report and glasses prescription
- Any earlier eye surgery, laser treatment or injections, with dates
- Diagnoses of other eye conditions such as glaucoma or diabetic eye disease
- A list of all medicines, including blood thinners and eye drops
- Notes on general health such as diabetes or blood pressure control
The hospital in India will repeat the lens measurements itself. That is expected and you should not skip it.
How should you plan the trip?
- Assessment: examination, measurements and lens discussion
- Surgery day: a day-care admission with the eye numbed
- Next-day review: MedlinePlus notes a follow-up exam usually takes place the day after
- Second eye: MedlinePlus says the eyes are often done at separate times, so ask whether you will have one or both
- Before flying: ask the surgeon when it is safe for you to fly
- Home: continued drops and a check with your own optician or eye doctor
MedlinePlus says someone must take you home after surgery. An attendant is useful for older patients. You will be putting in several eye drops and may feel unsteady. Keep soap and water out of the eye in the early days and avoid rubbing it, as both sources advise.
What should you ask the eye hospital?
- Which lens types do you offer and which suits my eyes?
- Will you operate on one eye or both during this visit?
- Who will see me the day after surgery?
- When will it be safe for me to fly home?
- What drops will I use and for how long, and can I get them at home?
- What happens if I need a laser treatment for clouding behind the lens later?
IndiaMedica helps you share reports and compare written plans. The treating ophthalmologist decides on surgery, lens and timing.
Questions people ask
Will I be awake during cataract surgery?
Adults are usually awake. MedlinePlus says the eye is numbed with drops or an injection and you are given medicine to relax. Moorfields says sedation is optional and discussed with the anaesthetist. Children usually have general anaesthesia.
Can clouding come back after cataract surgery?
The cataract itself does not return. Moorfields explains that some people later develop a cloudy membrane behind the new lens, which can be cleared with a laser procedure called YAG capsulotomy. Ask whether your own eye doctor at home can provide this if you need it.
Do I need my own eye doctor after surgery abroad?
Yes. You will continue drops at home and may need new glasses once the eye settles. MedlinePlus notes new glasses or contacts can usually be fitted after recovery. Take your discharge summary and lens details to your optician or eye doctor.
