This study looks at whether a laser procedure called femtosecond laser-assisted arcuate keratotomy (FSAK) helps people with both cataracts and mild astigmatism see more clearly after cataract surgery. Astigmatism causes blurry vision because the front of the eye (cornea) is curved unevenly. The FSAK procedure uses a computer-guided laser to make tiny, precise cuts in the cornea during cataract surgery to fix this curve. the investigators want to see if this improves vision long-term (up to 5 years) and what factors affect how the investigatorsll it works.\n\nWho can join? the investigators are looking for adults aged 20-80 years who:\n\nHave cataracts and mild-to-moderate astigmatism (0.75-2.0 diopters) Plan to have cataract surgery Have not had prior eye surgeries (like LASIK) Do not have severe dry eye or other eye diseases (like glaucoma or retina problems) What will happen in the study?\n\nSurgery: Participants will have cataract surgery combined with the FSAK procedure. The surgeon uses a laser to make tiny curved cuts in the cornea to reshape it.\n\nFollow-up visits: Participants will have regular eye check-ups for 5 years after surgery. These include:\n\nVision tests (reading eye charts) Measurements of the eye's shape using painless imaging machines Questionnaires about vision quality and daily activities Time commitment: Visits happen at 1 the investigatorsek, 1 month, 3 months, 6 months, 1 year, 2 years, and 5 years after surgery. Each visit takes about 1-2 hours.\n\nWhy is this study important? FSAK may help people with astigmatism see clearly after cataract surgery without needing glasses as often. By tracking results for 5 years, the investigators'll learn how long the benefits last and who benefits most. This could help doctors better personalize treatment in the future.\n\nWho is running the study? Eye doctors at Fudan University Eye \\& ENT Hospital (Shanghai) and Shanghai Peace Eye Hospital.
