不知道“时复”这种病症，每年到了特定时间就会发作。人们往往认为它没有严重的隐患，但它最终会成为祸患的根源。即使有精通眼科医术的大夫治愈了它，如果病后没有进行巩固治疗，或者患者原本视力就较差，看到别人发病就跟着发作（即“波累”，指受他人影响而诱发），这并不是因为医生故意拖延难治，而是因为疾病的根本原因尚未去除。
这大概是眼病没有得到彻底治疗，患者硬扛着忍受直到表面痊愈；或者是治疗不得法，为了戒除某些诱因而刻意回避，却反而触动了眼部脉络，导致病邪深入体内；再加上后续不再治疗，使得邪气与正气相互搏击，无法发散出去。于是到了每年的某个月、每月的某一天，病情就像花季或潮水一样，到时间就发作，过了时间又自行缓解。久而久之，等到被激发出明显症状时，才进行治疗。如果不治疗则不行，在未发作时询问其发作的原因和病本；在已发作时查验其形态颜色和病变部位，判断属于哪个脏腑，然后对症主治，最终才能达到不再复发的效果。绝对不可拘泥于五运六气或月令节气，一概使用按时令开具的药物投治，恐怕还没治好病，先因用药不当而损伤身体了。
有的眼科高手治愈此病，慢则两三年、快则八九个月后，再往后可能一个月发作几次，这也称为“时复”。这是因为病根未除，患者突然拒绝就医并停药，或者长期严格禁忌束缚，一时之间看似好了，但一旦在风霜中漫游，放纵嗜欲，这就等于自己召唤病邪回来，气血因此停滞注积，疾病沿着熟悉的旧路复发，必然从原来的经络发起。世人多责怪医生留下酒碗（暗示医生未尽责任或患者未遵医嘱），这是不对的。面对这种病症，更应当根据具体情况灵活用药，千万不要被前医使用的某个方剂固定住思维。所谓“薪尽火传”，怎么知道后来的治疗不会比现在更好呢？
还有一种情况是患者原本视力就不好，只要看到别人发病就跟着发作。这是由一时的气候气变所导致的。《内经》说：“百病皆生于气”，思虑过度则气机郁结，恐惧则气机下陷，惊骇则气机紊乱。患有习惯性时复症的人，其中的甘苦已经尝遍。看到别人生病，无不惊恐并联想到自己的病情，此时神气错乱失常。纵然外邪未必具有传染性，但那一线未了的病根，因宿疾感应而随即相通，所以就会发作。这就好比人正在打哈欠，如果身子疲倦，旁人当面模仿也会跟着打哈欠；嘴里感到干燥口渴，一提到梅子，舌下就会生津，道理是一样的。将此症列在本篇中，作为格物致知之余，我冒昧地以古人未能看到我（的文字/观点）为遗憾。
One may not be aware that the condition known as "Shi Fu" (Periodic Recurrence) arrives with each passing year at a specific time. People often assume it poses no deep threat, yet ultimately it becomes the seed of disaster. Even if a skilled ophthalmologist cures it, if post-treatment care is neglected, or if the patient's eyes were originally weak and they suffer recurrence upon seeing others afflicted—a phenomenon referred to as being "affected by waves" (influenced by others)—this is not due to the physician's deliberate difficulty in treatment, but because the root cause of the disease has not been eradicated.
This situation typically arises when an eye disease is not treated thoroughly, and the patient endures the symptoms until they appear to heal on their own; or when the treatment is inappropriate, and attempts to avoid triggers inadvertently disturb the meridians and collaterals of the eye, causing the pathogen to penetrate deeply. If left untreated subsequently, the pathogenic factor and healthy qi engage in combat without dispersing. Consequently, at certain months of the year or days of the month, the condition flares up like blooming flowers or rising tides, subsiding only after the period passes. Over time, once obvious symptoms are triggered, treatment begins. If untreated, it will not resolve; therefore, one must inquire about the underlying cause before onset, and upon onset, examine the morphology, color, and location to determine the affected Zang-Fu organs, then apply targeted therapy. Only then can permanent remission be achieved. One must absolutely not rigidly adhere to the theories of Five Movements and Six Qi or lunar terms, indiscriminately administering medications prescribed for seasonal timing, lest the medicine harm the body before curing the disease.
Some master physicians of the Eye Classics have cured this condition, with recurrences ceasing after two to three years, or quickly within eight to nine months; later, it might occur several times a month, which is also termed "Shi Fu." This occurs because the root remains, and the patient abruptly dismisses the physician and stops medication, or strictly adheres to prohibitions for a long time, appearing suddenly cured. However, once they wander in wind and frost or indulge in desires, they effectively summon the illness back. The qi and blood stagnate and accumulate, and the disease travels its familiar path, inevitably erupting from the original meridians. The common people often blame the physician for leaving behind wine bowls (implying negligence or failure to enforce abstinence), which is incorrect. When facing this condition, one must administer medication according to the specific circumstances and must not let the formulas used by previous physicians fixate one's mind. As the saying goes, "When the firewood is exhausted, the fire continues"; how can we know that future treatments will not surpass the current ones?
There is another scenario where patients with originally poor vision flare up whenever they see others suffering. This is caused by sudden changes in climatic qi. The Classic states: "All diseases arise from Qi." Excessive thinking causes Qi to knot; fear causes Qi to sink; shock causes Qi to become chaotic. Those accustomed to periodic recurrence have experienced its joys and sorrows fully. Seeing others ill, they inevitably feel fear and anxiety regarding themselves, causing their Shen (Spirit) and Qi to become disordered. Although external pathogens may not necessarily be contagious, the lingering thread of the old pathology connects through resonance with past karma/disease patterns, leading to immediate recurrence. It is akin to yawning: if one is tired, mimicking a yawn induces one; if one is thirsty, mentioning plums generates saliva in the mouth. The principle is identical. This condition is listed here as part of the study of things to acquire knowledge, and I dare to express regret that ancient sages did not witness my work.
