九窍的疾病中，以眼病最为严重，如果误治，导致失明的情况就不必说了。即使神膏（眼球内部透明组织）没有受损，遇到医术高明的人极力挽救，也难免会有微云点缀、杂质污染清澈天空般的瑕疵，实在令人痛恨。古人因此另立眼科专科，使得医生能够精通这一技艺，不至于因多途探索而迷失方向。无奈当今从事这一科的人，往往以发散攻伐作为主要手段，其造成的祸害怎能说得完呢！我的老师顾养吾先生，独自洞察灵兰秘典的深奥旨意，辨证斟酌处方，投药无不奏效，因此名声震动南北，远近患者争相求医，日日不断。侨居松江郡以来，积累的病例成千上万，今年春天，先生担心这些资料繁多而散失，收集其中已经验证有效的若干病症，编纂成两卷。又撰写了关于六淫外感、七情内伤杂病兼症等论述，并阐发五脏六腑主病的原理，无细微不剖析，无义理不搜罗，确实是眼科的指南，也是医学界的准则。他的立法详见于《治目总论》中，至于用方，则遵循张景岳的风格，用药则坚守张元素的原则，足见其与古人同行，心源契合。然而他巧妙运用神思，独抒己见，岂是浅学之人所能测度识别的呢？过去倪维德所著的《原机启微》一书，被薛立斋奉为至宝，刻入二十四种医书之内，其治法也以补益为主，与李东垣的脾胃学说、朱丹溪的滋阴理论，前后一脉相承，所以附带的医案很多。除此之外，各位名家对于眼目这一病症，都有条理清晰的论述，无不寒热虚实并列陈述，补泻温凉互相使用，只有张子和自己患有眼疾，有人用针刺出血而痊愈。于是推崇“血实则破之”的方法，创立了谬论，一变而为钩割手术，再变而为炮烙疗法，遭受其害者，几乎不可胜数。近来张飞畴能以金针拨障术，顷刻间取得功效，详细记载于《张氏医通》，确实神奇美妙。世间有传授此术的人，大家都羡慕它。然而治愈者固然多，受伤者也不在少数，总之不是善治之法。先生综合考核前贤的要旨，先探究本源，其次详述脏腑，然后涉及经络，依据脉象论述病症，应该能使昏沉者变得清晰，让疑惑者也能明白。回忆乙丑年秋季，我偶然罹患眼病，经过多位医生诊治，过度服用散风清火的药剂，几乎陷入黑暗（失明），幸赖先生之力，得以保留一线光明，仍能从事笔墨工作。然而长期困于考场，无心功名，偶尔窥探医籍，企图救人同时也救己，计划也算两全其美，于是跟随先生学习，先生将此书传授给我，口讲指画，犹如当头棒喝般警醒。因此请求刊印此书，以公之于志同道合者，使天下那些被误治的人，每天放在案头，按症状索取方剂，或许不至于再次犯错，从而造成无穷的后患，这难道不是百姓的大幸事吗？
嘉庆十二年岁次丁卯仲冬朔后二日，平湖受业门人郁芬百拜跋
Among the diseases of the nine orifices, eye diseases are the most severe. If mismanaged, blindness will inevitably occur. Even if the Shen Gao (transparent internal tissue of the eyeball) is not damaged, even with the utmost efforts of a skilled practitioner to rescue the condition, it is inevitable that minor clouds will dot the sky and impurities will pollute the clarity, which is truly regrettable. This is why the ancients established ophthalmology as an independent specialty, allowing practitioners to master one skill thoroughly, avoiding the loss of direction due to divergent paths. Unfortunately, contemporary practitioners in this field often rely on dispersing and attacking methods, the disastrous consequences of which are beyond enumeration. My teacher, Master Gu Yangwu, independently penetrated the profound secrets of the Linglan (Spiritual Repository) texts. By differentiating syndromes and selecting prescriptions, his treatments were invariably effective, earning him fame across the north and south, with patients from near and far flocking to him daily. Since settling in Songjiang Prefecture, he has accumulated thousands of cases. In the spring of this year, fearing that these records might be lost due to their volume, he collected several verified cases and compiled them into two volumes. He further wrote treatises on miscellaneous diseases complicated by external infections of the Six Evils (Liu Yin) and internal injuries caused by the Seven Emotions (Qi Qing), elucidating the primary diseases of the Zang-Fu organs with meticulous detail and comprehensive coverage. This work serves as a guide for ophthalmology and a standard for the medical community. His therapeutic principles are detailed in the "General Treatise on Treating Eyes." Regarding prescription formulation, he followed the style of Zhang Jingyue; regarding herb selection, he adhered to the principles of Zhang Yuansu, demonstrating his alignment with ancient masters and harmony of spiritual origin. However, his ingenious thinking and unique insights transcend the comprehension of superficial learners.
Previously, Ni Weide's book *Yuanji Qiwei* (Origin of Mechanisms Unveiled) was cherished by Xue Lizhai as a supreme treasure and included in the Twenty-Four Medical Books. Its therapeutic approach primarily emphasized tonification, consistent with Li Dongyuan's Spleen-Stomach theory and Zhu Danxi's Yin-nourishing theory, hence containing many attached case records. Apart from these major figures, all experts had systematic discussions on eye diseases, presenting cold, heat, deficiency, and excess simultaneously, and using tonifying, purging, warming, and cooling methods interchangeably. Only Zhang Hezi, who suffered from eye disease himself, was cured by someone pricking blood with needles. Consequently, he advocated the method of "breaking excess blood," creating erroneous theories that evolved first into hook-and-cut surgery and later into cauterization, causing harm to countless individuals. Recently, Zhang Feichou achieved remarkable results instantly using the Golden Needle Cataract Extraction technique, as detailed in *Zhangshi Yitong* (Medical Compendium of Mr. Zhang). This method is indeed miraculous, and those who possess it are envied by the world. Although many are cured, many others are injured; thus, it is not considered optimal treatment.
Master systematically reviewed the essential principles of former sages, first investigating the root causes, then detailing the Zang-Fu organs, and subsequently addressing the meridians. By analyzing pulses and symptoms, he enables the confused to become clear and the doubtful to understand. I recall in the autumn of the Yichou year, I accidentally contracted an eye disease. After seeing several doctors and overusing wind-dispersing and fire-clearing agents, I nearly fell into eternal darkness. Thanks to Master's efforts, I retained a sliver of light and could continue my scholarly pursuits. Having been confined to examination halls for years without ambition for official rank, I occasionally studied medical texts to save others and myself, believing this plan would benefit both. Thus, I sought to study under Master, who taught me this compilation. Through oral instruction and gestural explanation, he awakened me like a sudden blow to the head. Therefore, I requested its publication to share with colleagues, so that those misled by improper treatment may keep it at hand, consult prescriptions according to symptoms, and avoid repeated errors and endless harm. Is this not a great fortune for the people?
