Abstract
Age-related cataract is a leading cause of visual impairment due to progressive changes in the crystalline lens. Modern cataract surgery has evolved into a refractive procedure aimed at restoring high-quality vision at multiple distances. Advanced intraocular lenses, including multifocal and EDOF (extended depth-of-focus) designs, address these needs but may cause photic phenomena and reduced contrast sensitivity. Spiral optics is a novel approach based on continuous phase modulation, offering an extended range of vision with fewer optical side effects. Early studies show promising visual outcomes, though further research is needed to confirm long-term safety and efficacy.
