Cataract extraction; Cataract surgery

Cataract removal is surgery to remove a clouded lens ( cataract ) from the eye. Cataracts are removed to help you see better. The procedure almost always includes placing an artificial lens (IOL) in the eye.

Description

Cataract surgery is an outpatient procedure. This means you likely do not have to stay overnight at a hospital. The surgery is performed by an ophthalmologist. This is a medical doctor who specializes in eye diseases and eye surgery.

Adults are usually awake for the procedure. Numbing medicine (local anesthesia) is given using eye drops or a shot. This blocks pain. You will also get medicine to help you relax. Children usually receive general anesthesia. This makes them unconscious and unable to feel pain.

The doctor uses a special microscope to view the eye. A small cut (incision) is made in the eye.

The lens is removed in one of the following ways, depending on the type of cataract:

Phacoemulsification: With this procedure, the doctor uses a tool that produces sound waves to break up the cataract into small pieces. The pieces are then suctioned out. This procedure uses a very small incision.
Extracapsular extraction: The doctor uses a small tool to remove the cataract in mostly one piece. This procedure uses a larger incision.
Laser surgery: The doctor guides a machine that uses laser energy to make the incisions and soften the cataract. The rest of the surgery is much like phacoemulsification. Using the laser instead of a knife (scalpel) may speed recovery and be more accurate.

After the cataract is removed, a manmade lens, called an intraocular lens (IOL), is usually placed into the eye to restore the focusing power of the lens (cataract). It helps improve your vision.

The doctor may close the incision with very small stitches. Usually, a self-sealing (sutureless) method is used. If you have stitches, they may need to be removed later.

The surgery lasts less than half an hour. Most times, just one eye is done. If you have cataracts in both eyes, your doctor may suggest waiting at least 1 to 2 weeks between each surgery.

Why the Procedure Is Performed

The normal lens of the eye is clear (transparent). As a cataract develops, the lens becomes cloudy. This blocks light from entering your eye. Without enough light, you cannot see as clearly.

Cataracts are painless. They are most often seen in older adults. Sometimes, children are born with them. Cataract surgery is usually done if you cannot see well enough because of cataracts. Cataracts usually do not damage your eye, so you and your eye doctor can decide when surgery is right for you.

Risks

In rare cases, the entire lens cannot be removed. If this happens, a procedure to remove all of the lens fragments will be done at a later time. Afterward, vision can still be improved.

Very rare complications can include infection and bleeding. This can lead to permanent vision problems.

Before the Procedure

Before surgery, you will have a complete eye exam and eye tests by the ophthalmologist.

The doctor will use ultrasound or a laser scanning device to measure your eye. These tests help determine the best IOL for you. Usually, the doctor will try to choose an IOL that can allow you to see without glasses or contact lenses after surgery. Be sure you understand what your vision will be like after the IOL is implanted.

Your doctor may prescribe eye drops before the surgery. Follow instructions exactly on how to use the drops.

After the Procedure

Before you go home, you may receive the following:

A patch to wear over your eye until the follow-up exam
Eyedrops to prevent infection, treat pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation and help with healing

You will need to have someone drive you home after surgery.

You will usually have a followup exam with your doctor the next day. If you had stitches, you will need to make an appointment to have them removed.

Tips for recovering after cataract surgery:

Wear dark sunglasses outside after you remove the patch.
Wash your hands well before and after using eyedrops and touching your eye. Try not to get soap and water in your eye when you are bathing or showering for the first few days.
Light activities are best as you recover. Check with your doctor before doing any strenuous activity, resuming sexual activity, or driving.

Recovery takes about 2 weeks. If you need new glasses or contact lenses, you can usually have them fitted at that time. Keep your follow-up visit with your doctor.

Outlook (Prognosis)

Most people do well and recover quickly after cataract surgery.

If a person has other eye problems, such as glaucoma or macular degeneration, the surgery may be more difficult or the outcome may not be as good.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider

Tests to discuss with doctor

Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
Relevant blood, urine, imaging, or specialist tests only after clinical assessment

Questions to ask

What is the most likely cause of my symptoms?
Which warning signs mean I should go to emergency care?
Which tests are really needed now?
Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Go to emergency care if you notice:

Severe or rapidly worsening symptoms
Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration

Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.

Step 1
Check danger signs first
If danger signs are present, seek emergency care and do not wait for online information.
Step 2
Record the symptom story
Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.
Step 3
Visit a qualified clinician
A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.
Step 4
Do only useful tests
Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.
Step 5
Follow up and return early if worse
If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips

Take a written symptom diary and all previous prescriptions/test reports.
Do not hide medicines already taken, even herbal or over-the-counter medicines.
Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
