Clinical Study on the Effectiveness of Diverse Segments Defocus Optimization in Spectacle Lenses for Slowing Myopia Progression

Clinical Trial The goal of this clinical trial is to evaluate the effectiveness of two types of Diverse Segments Defocus Optimization (D.S.D.O.) spectacle lenses in slowing myopia progression in children. It will also assess the safety of these lenses. The main questions it aims to answer are: Do 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. Participants will: Wear assigned D.S.D.O. lenses daily for 12 months (except during sleep or unavoidable situations). Attend clinic visits at baseline, 3, 6, 9, and 12 months for comprehensive eye examinations. Maintain a diary recording daily wear time, visual symptoms, and any adverse events.

Toric Intraocular Lens (IOL) Implantation for Management of Cataracts

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.

Visual Outcomes of Functional Intraocular Lenses in Cataracts

This is a prospective, multi-center, randomized comparative study. The purpose of the study is to evaluate and compare the objective and subjective visual outcomes of different types of functional intraocular lenses (IOLs) in patients.
