Cataract, IOL, Johnson & Johnson Vision
CATARACT, LENS, IOL
Cataract surgery has evolved into lens-based refractive surgery with rapid intraocular lens (IOL) optical technology advances and improvements in equipment and techniques [The TECNIS Symfony EDOF IOL (Johnson & Johnson Vision, Santa Ana, USA) incorporates a specialized diffractive echelette design. This unique design effectively disperses light, resulting in an elongated focus and ensuring a seamless and unobstructed range of vision. In comparison to bifocal and trifocal IOLs, EDOF IOLs have limited visual results at near distance, but have a lower incidence of photic phenomena [
