It will also assess the safety of these lenses. The main questions it aims to answer are:\n\nDo D.S.D.O. lenses reduce the progression of myopia as measured by changes in cycloplegic refraction and axial length? What adverse events do participants experience when wearing D.S.D.O. lenses? Researchers will compare two optical designs of D.S.D.O. lenses (Intervention Group1: Design 1; Intervention Group2: Design 2) to determine their relative efficacy in controlling myopia progression.\n\nParticipants will:\n\nWear assigned D.S.D.O. lenses daily for 12 months (except during sleep or unavoidable situations).\n\nAttend clinic visits at baseline, 3, 6, 9, and 12 months for comprehensive eye examinations.\n\nMaintain a diary recording daily wear time, visual symptoms, and any adverse events.",[27,28,29,30,31],"Children With Myopia","Treatment","Multizone Lens Design for Myopic Defocus","Visual Quality","Efficacy","RECRUITING","2025-12-23",{"date":35,"type":36},"2026-01-07","ACTUAL",{"date":38,"type":36},"2024-08-02",{"date":40,"type":21},"2026-09-30",{"name":42,"class":43},"Beijing Tongren Hospital","OTHER",1,{"id":46,"slug":47,"hasResults":11,"nctId":48,"briefTitle":49,"officialTitle":50,"acronym":4,"eligibilityCriteria":51,"healthyVolunteers":15,"sex":16,"minAge":4,"maxAge":4,"enrollmentInfo":52,"targetDuration":4,"studyType":54,"phases":4,"briefSummary":55,"conditions":56,"keywords":4,"overallStatus":32,"whyStopped":4,"lastUpdateSubmitDate":58,"lastUpdatePostDateStruct":59,"startDateStruct":61,"completionDateStruct":63,"leadSponsor":65,"locationsCount":67},"100500518","toric-intraocular-lens-iol-implantation-for-management-of-cataracts-100500518","NCT05797298","Toric Intraocular Lens (IOL) Implantation for Management of Cataracts","Plate-haptic Toric Intraocular Lens (IOL) Implantation for Management of Cataracts","Inclusion Criteria:\n\n* Cataract\n\nExclusion Criteria:\n\n* • small pupil\n\n  * zonular dehiscence\n  * preexisting corneal pathology\n  * glaucoma\n  * uveitis\n  * a history of ocular trauma or surgery\n  * severe intraoperative and postoperative complications",{"count":53,"type":21},3000,"OBSERVATIONAL","This study included cataract patients who underwent toric intraocular lens (IOL) implantation, which aimed to evaluate the stability and clinical visual quality of toric IOLs.",[57,30],"Toric Intraocular Lens Stability","2025-06-16",{"date":60,"type":36},"2025-06-19",{"date":62,"type":36},"2019-06-01",{"date":64,"type":21},"2030-05-31",{"name":66,"class":43},"Eye & ENT Hospital of Fudan University",2,{"id":69,"slug":70,"hasResults":11,"nctId":71,"briefTitle":72,"officialTitle":73,"acronym":4,"eligibilityCriteria":74,"healthyVolunteers":11,"sex":16,"minAge":75,"maxAge":4,"enrollmentInfo":76,"targetDuration":4,"studyType":54,"phases":4,"briefSummary":78,"conditions":79,"keywords":4,"overallStatus":81,"whyStopped":4,"lastUpdateSubmitDate":82,"lastUpdatePostDateStruct":83,"startDateStruct":85,"completionDateStruct":87,"leadSponsor":89,"locationsCount":4},"100523172","visual-outcomes-of-functional-intraocular-lenses-in-cataracts-100523172","NCT06092164","Visual Outcomes of Functional Intraocular Lenses in Cataracts","Visual Outcomes of Different Types of Functional Intraocular Lenses in Cataract Patients","Inclusion Criteria:\n\n* cataract\n* age \\> 18 years\n\nExclusion Criteria:\n\n* amblyopia; previous ocular surgery;\n* ocular pathologies such as diabetic retinopathy, macular degeneration, glaucoma with field defects;\n* requirements for further ocular surgery (other than Nd:YAG capsulotomy) or retinal laser treatments during the study","18 Years",{"count":77,"type":21},20000,"This is a prospective, multi-center, randomized comparative study.
