Today, it is considered one of the most successful and commonly performed surgical procedures worldwide when performed on appropriately selected patients.

What Is Cataract Surgery?
Cataract surgery is a microsurgical procedure designed to restore vision by removing the eye’s clouded natural lens and replacing it with a clear artificial lens called an intraocular lens (IOL).
Unlike glasses, which improve vision externally, cataract surgery addresses the underlying cause of vision loss by replacing the affected lens itself.
Most procedures in Korea are performed as outpatient surgery under local anesthesia, allowing patients to return home the same day.
Why Do International Patients Choose Gangnam for Cataract Surgery?
Gangnam has become one of Korea’s leading medical districts, attracting patients from Asia, the Middle East, Europe, North America, and Australia.
Several factors contribute to its popularity:
- Highly experienced ophthalmic surgeons
- Modern diagnostic imaging and surgical technology
- Premium multifocal and toric lens options
- Efficient scheduling with minimal waiting periods
- English-speaking coordinators and interpreter services
- Convenient transportation from Incheon International Airport
- High standards of infection control and patient safety
Many clinics also provide dedicated international patient centers that assist with appointment scheduling, accommodation recommendations, airport transfers, and postoperative follow-up planning.
What Causes Cataracts?
A cataract develops when proteins inside the eye’s natural lens gradually break down and clump together, causing cloudiness that interferes with light reaching the retina.
Common causes include:
- Aging
- Diabetes
- Long-term steroid medication use
- Previous eye injuries
- Smoking
- Excessive ultraviolet (UV) exposure
- Certain inherited conditions
Although aging is the most common cause, cataracts may also occur in younger adults or, rarely, children.
Common Symptoms of Cataracts
Symptoms often develop gradually and may include:
- Blurred or cloudy vision
- Difficulty driving at night
- Increased glare from headlights
- Colors appearing faded or yellowish
- Frequent changes in eyeglass prescriptions
- Double vision in one eye
- Increased sensitivity to bright lights
Patients often describe the experience as looking through a foggy or dirty window.
When Is Cataract Surgery Recommended?
Surgery is generally recommended when cataracts begin interfering with daily activities rather than based solely on the cataract’s appearance.
Examples include:
- Difficulty reading
- Problems driving safely
- Trouble recognizing faces
- Reduced work performance
- Poor vision despite updated glasses
Modern ophthalmologists emphasize improving quality of life rather than waiting until cataracts become “mature.”
How Cataract Surgery Is Performed
Step 1: Comprehensive Eye Examination
Before surgery, ophthalmologists evaluate:
- Cataract severity
- Corneal health
- Retina condition
- Eye pressure
- Tear film quality
- Overall eye measurements for IOL calculation
Advanced optical biometers help determine the appropriate lens power with high precision.
Step 2: Local Anesthesia
Most patients receive anesthetic eye drops rather than general anesthesia.
The procedure is generally painless, though mild pressure sensations may occur.
Step 3: Phacoemulsification
Most Korean clinics perform phacoemulsification.
During this procedure:
- A tiny incision is created.
- Ultrasound energy breaks the cloudy lens into small fragments.
- The fragments are removed.
- A folded artificial lens is inserted through the same incision.
- The lens unfolds naturally inside the eye.
The incision is usually self-sealing and often does not require stitches.
Step 4: Recovery
Patients typically rest briefly before returning home the same day.
Vision often begins improving within several days, although complete healing may take several weeks depending on individual circumstances.
Types of Intraocular Lenses (IOLs)
Selecting the appropriate IOL is one of the most important decisions in cataract surgery.
Monofocal Lens
Provides excellent distance vision.
Patients generally require reading glasses afterward.
Suitable for:
- Patients prioritizing sharp distance vision
- Individuals seeking a cost-effective option
Multifocal Lens
Designed to reduce dependence on glasses by providing vision at multiple distances.
Advantages:
- Improved near vision
- Better intermediate vision
- Greater lifestyle convenience
Not every patient is an ideal candidate, particularly those with certain retinal conditions.
Toric Lens
Corrects astigmatism in addition to cataracts.
Recommended for patients with significant corneal astigmatism.
Extended Depth of Focus (EDOF) Lens
Provides a continuous range of vision with fewer visual disturbances than some multifocal designs.
Increasingly popular among active adults.
Recovery After Cataract Surgery
Most patients recover quickly.
Typical recovery timeline:
First 24 Hours
- Mild irritation
- Blurred vision
- Protective eye shield at night
First Week
- Vision becomes noticeably clearer
- Eye drops reduce inflammation and prevent infection
One Month
- Most healing completed
- Final vision assessment
- Updated glasses if needed
Patients should avoid:
- Heavy lifting
- Swimming
- Eye rubbing
- Dusty environments
- Eye makeup for the recommended period
