上唐仙人所着书，传之方外，至大瓢七眉先生口授王覆万，覆万口授马云从，云从广咨博采，
推阐微妙，其间沙蒙灰眯，么么必录，室女小儿，纤细无遗。病目者固当朝夕以之，即目无病者，思患
予防，亦不可斯须去身。

平童子时，从先冰陶兄试青州，即耳云从有声庠序间。后四十年，为皇清丁君始邂逅于
潍西，颓然老翁也，相得甚欢，及道落魄之由，乃知以目病废举子业。溯其病目时，俗医攻其外，不
知治其本，试万方，目将瞽，虔祷于城隍尊神，梦神赐书四帙，帙豆青色，内墨书，句读处朱界之。
晨起遇江南王覆万授书，如梦中所见，乃孙真人《眼科秘诀》。如法自医自愈，医人人亦愈，人获真人之赐
久矣。今化龙老，恐旦暮死，而此书不行于世；即旦暮未死，亦行于一方，不能遍宇内也。因发愿刊

这是唐代仙人所著的书籍，在方外之人中流传。到大瓢七眉先生时，口头传授给王覆万；王覆万又口头传授给马云从。马云从广泛咨询并博采众长，推演阐发其中的精微奥妙。书中对于像沙石蒙眼、灰尘眯眼这样细小的病症，也必定收录；对于室女（未婚女子）和儿童这类特殊人群，记载得细致入微，毫无遗漏。患有眼疾的人固然应当早晚研读此书；即使眼睛没有疾病的人，为了防患于未然，也不可片刻离身。
半舫主人 自述
我小时候，跟随先兄冰陶去青州应试时，就听说马云从在地方学宫（庠序）间已有名声。后来过了四十年，在清朝丁亥年，我在潍水西岸初次与他邂逅相见，那时他已是一位颓然的老翁了。我们相处得非常愉快，等到他谈起自己落魄的原因，才知道是因为眼病而废弃了举子（科举）学业。追溯他患眼病的时候，世俗医生只攻击治疗眼部表面症状，不知道治本，尝试了无数方法，眼看眼睛就要失明。于是他虔诚地祈祷城隍尊神，梦见神明赐予他四册书，书皮是豆青色的，里面用墨书写，句读停顿的地方用红笔圈界。第二天早晨起来，遇到江南的王覆万传授给他这本书，正如梦中所见，这就是孙真人（孙思邈）的《眼科秘诀》。他按照书中的方法自我医治并痊愈，医治别人别人也痊愈，人们获得这位真人的恩赐已经很久了。如今化龙（马云从的字或号）年老，恐怕早晚就会去世，而这本书不能流行于世；即使早晚不死，也只能在一地流传，不能遍及天下。于是发愿刊印发行，但又因绵薄之力未能完成此事，说完话后，感慨叹息，不能自已。当时秋月满庭，清爽之气逼人，我听到他的话，猛然有所触动，于是拿出我的积蓄（砚田金），为他完成了这件事。马云从又说，《秘诀》虽然刊行了，《阐微》却没有刊行，谁能真正神解其意呢？我四处寻找《阐微》，最终将其全部交付刻印。虽然是贤人君子，或许能在用餐之余，共同成就不朽之书，然而三四年来的艰难困苦中，我未曾敢在早晚忘记督促刻工，这是因为知道马云从是为天下后世著书，而我马云从为刻书，坚守旧约不忘初衷，私下里对此十分仰慕。如果说：书成之后，平分医治众人的功劳，那就不是我所考虑的了。
庚辰夏五月，王古诸冯昆铁隋平 叙
This book was authored by an Immortal of the Tang Dynasty and circulated among those outside the secular world. It was passed down orally from Master Da Pao Qi Mei to Wang Fuwan, who then orally transmitted it to Ma Yuncong. Ma Yuncong consulted widely and collected extensively, deducing and elucidating its subtle mysteries. Minor ailments such as sand in the eyes or dust irritating the eyes were necessarily recorded; for maiden women and children, details were captured meticulously without omission. Those suffering from eye diseases should certainly study this book day and night; even those with healthy eyes, for the sake of preventive care against potential illness, should not be without it for a moment.
By the Half Boat Owner (Banfang Zhuren)
In my childhood, when I accompanied my elder brother Bingtao to Qingzhou for the imperial examinations, I had already heard that Ma Yuncong was well-known within the local academy circles. Forty years later, during the Dinghai year of the Great Qing, I first encountered him west of the Wei River. He was then a decrepit old man, yet we got along very well. When he recounted the reasons for his downfall, I learned that he had abandoned his scholarly pursuits due to eye disease. Tracing back to the time of his illness, worldly physicians only treated the external symptoms, failing to address the root cause. After trying countless remedies, his vision was on the verge of blindness. In desperation, he devoutly prayed to the City God (Chenghuang), dreaming that the deity bestowed upon him four volumes of books. The covers were bean-green, the text written in black ink, with red circles marking the punctuation. Upon waking, he met Wang Fuwan from Jiangnan, who handed him the book exactly as seen in the dream: Sun Zhenren’s (Sun Simiao) *Secrets of Ophthalmology* (Yanke Mijue). Following the methods therein, he cured himself and others, and people have long benefited from the grace of this True Man. Now, Hualong (Ma Yuncong's courtesy name or pseudonym) is old and fears death may come at any moment, leaving this book unprinted and unknown to the world; even if he lives longer, it would only circulate locally, not throughout the empire. Thus, he vowed to publish it, but lacking sufficient resources, could not complete the task. After speaking, he sighed with emotion, unable to restrain himself. At that time, the courtyard was filled with autumn moonlight, and the crisp air was invigorating. Hearing his words, I was suddenly moved, so I contributed my savings ("inkstone gold") to help him finish the project. Ma Yuncong added that while *Secrets* has been published, *Chanwei* (Elucidation of Subtleties) has not, asking who could truly grasp its profound meaning. I searched for *Chanwei* and eventually submitted the entire work to the press. Although sages and gentlemen might compose immortal works during leisure moments like dining, amidst the hardships and difficulties of the past three to four years, I never dared to forget urging the printers morning and night. This is because I know Ma Yuncong wrote for the benefit of the world and future generations, while I commissioned the printing for him. Keeping our original agreement in mind, I hold deep admiration for this spirit. If one says that completing the book allows me to share in the merit of healing people, that was not my intention.
