about Lai Sim's recovery.

August 24, 2021

Lai Sim is a 69-year-old grandmother with one daughter, three sons, and seven grandchildren. Lai Sim sells vegetables at the market and lives with her eldest daughter who works in a garment factory. Her husband passed away 15 years ago. Lai Sim likes to listen to the monks pray on the radio.

Two years ago, Lai Sim developed a cataract in her left eye, causing her blurry vision and photophobia. She has difficulty seeing things clearly, recognizing faces, and going anywhere outside.

When Lai Sim learned about our medical partner, Children’s Surgical Centre, she traveled for two and a half hours seeking treatment. On August 24th, doctors will perform a small incision cataract surgery and will implant an intraocular lens in her left eye. After recovery, she will be able to see clearly. Now, she needs help to fund this $229 procedure.

Lai Sim said, “After surgery I hope my eye can see clearly as a young person again. I want to take care of my grandchildren more.”

​What kinds of symptoms do patients experience before receiving treatment?

Patients with cataracts experience decreased vision, discomfort, and irritation. Cataracts occur when the lens inside the eye becomes cloudy, causing functional blindness. These changes in the lens commonly occur with increasing age and therefore affect elderly people. Cataracts can also be congenital or traumatic.

​What is the impact on patients’ lives of living with these conditions?

The decreased vision from cataracts can cause functional blindness. This makes it difficult for the patient to conduct daily activities. Patients often need a family member to help guide and care for them. If the patient is elderly, this often affects a young child in the family. When a grandmother needs help getting around, a young child is often assigned to help with her daily tasks. That child cannot go to school.

What cultural or regional factors affect the treatment of these conditions?

In many countries in the developing world, surgical services are inadequate. Cataracts remain the leading cause of blindness globally. Even where surgical services are available, barriers to surgery remain, including cost, shortage of human resources, poor infrastructure, and limited awareness about access to available services.

What does the treatment process look like?

Cataract surgery is the most common surgery performed worldwide. Surgeons remove the cloudy lens and place a clear lens implant in its place.

What is the impact of this treatment on the patient’s life?

A patient's vision can improve to 20/20 within one day after the surgery.

What potential side effects or risks come with this treatment?

Cataract surgery is highly effective and carries a low risk.

How accessible is treatment in the area? What is the typical journey like for a patient to receive care?

Cataract surgery is available in most areas of Cambodia. However, free surgery is not as widely available.

What are the alternatives to this treatment?

Some debilitating effects of cataracts can be improved with glasses. When the cataract becomes mature, however, the only definitive treatment is surgical.
