什么是白内障

白内障是一种眼睛晶状体逐渐混浊的疾病,最常见为‘老年性白内障’。它会导致视线模糊,甚至失明,并是首位致盲性眼疾。

白内障手术

手术是唯一有效治疗白内障的方法。该疗程是在局部麻醉的情况下进行不超过20分钟的日间手术 (可采用保健储蓄户口付款)。经过勿须缝合或动刀的小切口超声乳化手术后,患者可在手术后隔天内恢复视力。眼科中心也提供合适的人工晶体植入包括单焦距球面、散光单焦距或多焦距(双焦距、三焦距和可扩展焦距)晶体,帮助患者摆脱近视、远视、甚至‘老花’等视力问题。患者也可使用健保双全(Medishield)支付手术费。

由于各种晶体植入有其利与弊,您必须与眼科医生详谈最适合您生活习惯的晶状体植入。欲知详情,欢迎莅临本诊所。

手术可彻底消除白内障,但是有百分之二十的患者,在接受晶体植入的眼睛会产生眼袋肿胀。此症状可透过YAG激光这项门诊手术消除。若在白内障手术后出现视力模糊,您必须立刻就诊接受眼部检查。

白内障的成因

随着年龄的增长,白内障的发病率会逐渐提高,尤其在过度暴露于阳光紫外光下。其次,较年轻的患者,尤其是有高度近视或糖尿病的,在受到眼部挫伤或眼内炎症后,也可能患上白内障。长期服用类固醇药物也可引发该眼疾。

白内障的症状

典型的白内障的临床表现是视力逐渐模糊或色彩渐进性暗黄。其他眼疾恶化的现象包括所见色彩暗淡、眩光或经常需要更換眼镜等。

如何诊断白内障

眼科医生会应用裂隙灯显微镜来诊断白内障。在决定进行白内障手术前,患者必须经过详尽的眼部检查以排除其他的眼部异常症状的可能性。

(English) Treatment of Diabetic Retinopathy

(English) Because treatment of this condition is not a cure, it is generally advised to prevent diabetic retinopathy first with healthy lifestyle and eye care choices. DR can be managed and its effects even slowed, but it is better to reduce your risk of needing to do that in the first place.

That means practising good sugar control, among other things. This can be achieved by having regular meals, a healthy diet, and regular exercise. Controlling other chronic medical conditions like high blood pressure and high cholesterol is important as well, as they are hypothesised to have adverse effects on the tiny blood vessels in the eyes.

Beyond prevention, there is also early detection. The earlier the condition is found, the sooner it can be managed, which means it has less time to progress into a severe enough state for lasting vision loss. Annual eye screening is crucial in picking up any developing DR early, due to this. Screening should be done more frequently in newly diagnosed diabetics too, as these are typically patients whose blood sugar control is not yet optimal. The same goes for those with a condition that puts them at higher risk for DR, e.g. pregnancy with diabetes.

Once diagnosed, diabetic retinopathy itself can be treated in several ways:

Argon laser treatment Also known as panretinal photocoagulation, this is a procedure that involves using a laser to treat the retina. The main aim is to prevent the growth of the abnormal fragile vessels, and to prevent severe vision loss.
Anti-VEGF agents Injection of anti-VEGF agents into the back cavity of the eye, is another common treatment option. VEGF stands for vascular endothelial growth factor. The agents therefore prevent the growth of new blood vessels, and also help to prevent leakage from other blood vessels that are causing swelling at the macula.
Surgery In some cases of severe diabetic retinopathy, where bleeding into the vitreous cavity has already occurred, or there is tractional retinal detachment which is threatening the central vision, a surgery known as a vitrectomy is performed. This is done to remove the scar tissue and blood, and further argon laser can be done during the surgery
