Cataract is the most common cause of poor vision in the elderly. It is a curable form of blindness. Do not ignore any emerging symptoms. Have regular check-ups with an eye specialist. Early detection can prevent permanent blindness.

Cao Thang Eye Hospital's Cataract department is designed to give each patient the ultimate experience in same day surgical procedures with unrivaled quality of care. It is fully equipped with state-of-the-art technology to perform a number of ophthalmic procedures. Our well-trained ophthalmologists perform thousands of cataract surgeries each year.

What is Cataract?

A cataract is a clouding of the lens in the eye that affects vision. Cataracts are common in older people. A cataract can occur in either or both eyes. It cannot spread from one eye to the other.

As we age, some of the proteins in our eyes may clump together and start to cloud a small area of the lens. This is a cataract. Over time, the cataract can grow larger and cloud more of the lens, making it harder to see.

Researchers suspect that there are several causes of cataract, such as smoking and diabetes. Or, it may be that the protein in the lens just changes clumps from the wear and tear it takes over the years.

Cataract Symptoms

The most common symptoms of a cataract are:

-Cloudy or blurry vision.

-Colors seeming faded.

-Seeing glare with light sources such as headlights, lamps, or sunlight. A halo may appear around lights.

-Double vision or multiple images in one eye. (This symptom may clear as the cataract gets larger.)

-Frequent prescription changes in your eyeglasses or contact lenses.

These symptoms also can be a sign of other eye problems. If you have any of these symptoms, check with your eye care professional.

The Service

Cao Thang Eye Hospital Cataract Surgery Service comprises a team of Phacoemulsification specialists and is headed by Dr. Nguyen My Dung.

Cataract Surgery and Refractive Correction

Patients’ expectations follow technological progress. It has become a common choice to take advantage of a cataract removal surgery to undergo a refractive correction procedure simultaneously and attain spectacle-free vision. Cao Thang Eye Hospital’s specialists can suggest a broad range of Intraocular Lenses (IOL) models to patients, from basic to premium lenses. Each patient gets a lens customised to perfectly fit their eye. However, patients are informed that other eye pathologies may prevent them from achieving a restored vision.
