Dry Eye Syndrome
什麼是乾眼症？ What is Dry Eye Syndrome ?
「乾眼症」指的是眼睛淚液分不夠或是分佈不均勻或淚液過度蒸發，造成淚液無法適當的保持眼球表的濕潤所造成。常見之症包括眼睛乾乾澀澀、容易疲倦、痕癢、痛灼熱感、眼皮緊繃沉重、分泌物黏稠、怕風、畏光、對外界刺激很敏感、暫時性視力模糊；有時眼睛太乾、基本淚液不足反而刺激反射性淚液分而造成常常流眼淚之症；較 嚴重者眼睛會紅、腫、充血、角質化， 角膜上皮破皮有絲狀物黏附，長期之傷害則會造成角結膜病變，並會影響視力。
Dry eye syndrome is caused by a chronic lack of sufficient lubrication and moisture on the surface of the eye. Symptoms usually affect both eyes and often include feelings of dryness, grittiness or soreness that get worse throughout the day, burning and red eyes, eyelids that stick together when you wake up temporarily blurred vision. The symptoms of dry eye syndrome are mild for most people, although more severe cases can be painful and lead to complications.

乾眼症類別 Types of Dry Eye
淚液過度蒸發乾眼症 Evaporative Dry Eye
Evaporative Dry Eye, also known as Meibomian Gland Dysfunction accounts for 86% of all dry eye and is caused by blockage of the meibomian glands that line the lash margin. The limited secretion of oil by these glands leads to quick evaporation of tears.
淚液缺乏性乾眼症 Aqueous Dry Eye
Aqueous Dry Eye occurs when the lacrimal gland does not produce enough of the water component to keep the eyes moist. This results in concentrated tear film (hyperosmolarity) and unstable tear film. The final conclusion is a dry ocular surface.
乾眼症療程 Dry Eye Treatment
Cocktail Light Therapy on Dry Eye Syndrome is a revolutionary treatment for Evaporative Dry Eye. The treatment uses powerful pulses of light (in the 500 to 800 nm wavelengths) to introduce an anti-bacterial and anti-inflammatory response in the eyelid and surrounding tissues (notably, the meibomian glands, which are targeted directly). It sounds complicated, but in reality, it’s simply a very technologically advanced warm compress. This treatment causes the glands to secrete more normal fluids, improving your tear quality.

Treatments typically require three to four sessions in a month interval to normalize the glands, with maintenance sessions once or twice per year thereafter.
