此眼初患之时。都无痒痛。还从一眼先患。后乃相牵俱损。皆因脑中热风冲入眼内。脑脂流下。凝结作翳。如银针
之色，虽不见人物。犹见三光。宜用金针拨之。然后宜决明散、坠翳丸神效。
诗曰∶
浮翳正观如透外 乍看色白似银灯 阴宽阳小随开合 此则深知是本形
辨认既能无错谬 金针拨出近乌睛 但根据教法施心力 免触凝脂破不明
决明散
石决明 人参 茯苓 大黄 车前子 细辛（各一两） 防风（二两） 茺蔚子（二两） 桔梗（一两半）
上为末。每食后米饮汤调下一钱。
坠翳丸
石决明 细辛（各一两） 知母 干地黄 防风（各一两） 兔肝（一具炙） 五味子 人参（各二两半）
上为末，炼蜜为丸如桐子大。空心茶下十丸。
此眼初患之时。肝脏劳热，还从一眼先患。或见黑花。后即相牵俱损。脑中热气流下，犹辨三光。宜令金针拨之。
然后服羚羊角饮子、空青丸即瘥。
诗曰∶
一般四障又名沉 隐隐藏形黑未深 向日细看方得见 自古相传不是今
此障拨时须远穴 观君莫要短头针 坠翳强过五十息 只求牢固莫他心
羚羊角饮子

**一、浮翳内障**
这种眼病在初发时，完全没有瘙痒或疼痛的感觉。通常先从一只眼睛发病，随后牵连另一只眼睛也受损。这都是因为脑中的热邪风邪冲入眼内，导致脑脂流下，凝结形成翳障。翳障的颜色像银针一样，虽然看不见具体的人物形象，但还能看见天日、月光、星光这“三光”。适宜用金针进行拨治。之后宜服用决明散或坠翳丸，疗效神效。
诗曰：
浮翳正看如同透过外层薄膜，乍一看颜色洁白好似银灯。瞳孔随阴阳之气宽窄开合，对此深入了解才能知晓其本形。
既然辨认无误没有差错，用金针拨出后靠近黑睛（角膜）。只要依据教法用心施治，就能避免触动凝脂导致视力不明。

**二、沉翳内障**

诗曰：
这一类四障又被称为沉翳，隐蔽身形且黑色尚未深重。对着太阳仔细观看才能发现，自古相传并非今日新创。

This text describes two types of eye diseases: Floating Cataract (Floating Opacity) and Sunken Cataract (Sunken Opacity).
**I. Floating Cataract (Floating Opacity)**
When this eye disease first occurs, there is no sensation of itching or pain. It typically begins in one eye and subsequently affects the other. This is caused by wind-heat pathogens from the brain rushing into the eyes, causing brain fluid to flow downward and coagulate into an opacity. The opacity resembles the color of a silver needle; although specific figures cannot be seen, the "Three Lights" (sun, moon, and stars) are still visible. It is suitable to use a gold needle for cataract surgery (needle extraction). Thereafter, it is advisable to administer Jueming San (Clear Bright Powder) or Zhuibi Wan (Opacity-Dropping Pill), which yield miraculous effects.
Poem:
Viewing floating opacity directly appears as if looking through an outer membrane; at first glance, its color is white like a silver lamp. The pupil expands and contracts with the balance of Yin and Yang; deep understanding reveals its true nature.
Once identified without error, using a gold needle to extract it brings it close to the black pupil (cornea). As long as treatment follows the prescribed methods with diligence, one can avoid disturbing the coagulated fluid and preserve clear vision.
**Jueming San (Clear Bright Powder)**
Ingredients: Shijueming (Haliotidis Concha), Renshen (Ginseng Radix et Rhizoma), Fuling (Poria), Dahuang (Rhei Radix et Rhizoma), Cheqianzi (Plantaginis Semen), Xixin (Asari Radix et Rhizoma) (each 1 liang); Fangfeng (Saposhnikoviae Radix) (2 liang); Chongweizi (Leonuri Fructus) (2 liang); Jiegeng (Platycodonis Radix) (1.5 liang).
Preparation and Administration: Grind the above ingredients into fine powder. After each meal, take 1 qian mixed with rice water.
**Zhuibi Wan (Opacity-Dropping Pill)**
Ingredients: Shijueming (Haliotidis Concha), Xixin (Asari Radix et Rhizoma) (each 1 liang); Zhimu (Anemarrhenae Rhizoma), Dihuang (Rehmanniae Radix), Fangfeng (Saposhnikoviae Radix) (each 1 liang); Tugan (Leporis Hepatis Praeparatum) (one liver, roasted); Wuweizi (Schisandrae Fructus), Renshen (Ginseng Radix et Rhizoma) (each 2.5 liang).
Preparation and Administration: Grind the above ingredients into fine powder, mix with refined honey, and form pills the size of paulownia seeds. Take 10 pills on an empty stomach with tea.
**II. Sunken Cataract (Sunken Opacity)**
When this eye disease first occurs, there is heat due to liver labor/exhaustion. It also begins in one eye initially. One may see black flowers dancing before the eyes, followed by involvement of the other eye. Heat qi from the brain flows downward, yet the patient can still distinguish the "Three Lights." It is advisable to have a practitioner perform needle extraction with a gold needle. Thereafter, taking Lingyangjiao Yinzi (Antelope Horn Decoction) or Kongqing Wan (Blue Azurite Pill) will lead to recovery.
Poem:
This category of four obstructions is also called Sunken Opacity; it hides its form, and the darkness is not yet deep. Only when looking carefully towards the sun can it be seen; it has been passed down since ancient times, not created today.
When extracting this opacity, the acupuncture point selected must be distant; observe that the physician does not use a short-headed needle. Manipulation should last more than fifty breaths (xi); seek firmness and do not let your mind wander.
**Lingyangjiao Yinzi (Antelope Horn Decoction)**
Ingredients: Lingyangjiao (Saigae Tataricae Cornu), Fangfeng (Saposhnikoviae Radix), Chongweizi (Leonuri Fructus) (each 2 liang); Cheqianzi (Plantaginis Semen), Heishen (Polygoni Multiflori Radix - specifically processed black root), Huangqin (Scutellariae Radix) (each 1 liang); Dahuang (Rhei Radix et Rhizoma) (0.5 liang).
Preparation and Administration: Grind the above ingredients into fine powder. Take 1 qian of the powder with one cup of water, decoct until reduced to half a cup, strain while warm, and take on an empty stomach.
**Kongqing Wan (Blue Azurite Pill)**
Ingredients: Kongqing (Azurite) (1 zhu); Wuweizi (Schisandrae Fructus), Cheqianzi (Plantaginis Semen), Xixin (Asari Radix et Rhizoma) (each 1 liang); Fangfeng (Saposhnikoviae Radix), Shengdihuang (Rehmanniae Radix), Zhimu (Anemarrhenae Rhizoma) (each 1 liang); Shijueming (Haliotidis Concha) (1 liang, separately ground finely).
Preparation and Administration: Grind the above ingredients into fine powder, mix with refined honey, and form pills the size of paulownia seeds. Take 10 pills on an empty stomach with tea.
