Only the elderly can get cataracts?

Cataracts can affect anyone – from babies to people in their 90s. Long-term exposure to ultraviolet rays may worsen cataracts, but even people who avoid ultraviolet rays will still have cataracts when they get older, In addition to older factors, cataracts can be caused by congenital, traumatic, diabetes, drugs and radiation.

Cataract surgery can only be performed on fully fledged cataracts?

No, patients do not need to wait for cataracts to mature. In the advanced stage of cataract, the lens will expand or even dissolve, which in turn will cause glaucoma, which can lead to irreversible blindness, and advanced cataract surgery is more difficult and vision recovery is slower.

Q: 80歲已沒有必要做白內障手術？

Cataract is a major eye disease that causes blindness in the elderly. Even if they are not blind, the long-term blurred vision of the elderly will not only seriously affect the quality of life of the elderly, but also cause danger.

白內障是導致長者失明的一大眼睛疾病，可是圍繞其症狀和治療方法仍然存在著許多誤解，最常見的包括以下問題：

只有長者才會患白內障嗎？

白內障會影響任何人，從嬰兒到90多歲的人。

長期暴露於紫外線下可能會使白內障惡化，但即使避開紫外線的人，在變老時仍會患上白內障。

除了年長因素外，先天性、外傷、糖尿病、藥物及放射等皆可能會引起白內障。

80歲已沒有必要做白內障手術？

白內障是導致長者失明的一大眼病。即使未至失明，但長者會長期處於視力模糊的狀態，不單止嚴重影響長者的生活質素，也會造成危險。

目前沒有治療白內障的有效藥物，治療白內障最理想的方法就是做手術，摘除已混濁的晶狀體，換上人工晶體。

不論任何年齡，若生活上有需要，並且身體情況許可，皆可考慮接受白內障手術。

白內障手術只能在完全成熟的白內障上進行嗎？

否。患者不需等待白內障成熟。

白內障到了晚期，晶狀體會膨脹甚至溶解，繼而引發青光眼，導致不可逆轉的失明，而且晚期白內障手術難度較大，視力恢復也更慢。

白內障手術會很痛？

白內障手術大多會採用眼部麻醉，痛楚很小，大部分長者都能接受。

有文獻報道，相比於第一隻眼的白內障手術，第二隻眼做白內障手術時患者的痛感略有增加。

人工晶體壽命很短？

現時人工晶體的物料，物理及化學性質非常穩定，患者可終身使用。

視力不良一定是白內障引起的？
白內障手術完成後，視力是否馬上就會變好？
