History of Intraocular Lens and IOL Power Calculation

The development of intraocular lenses (IOLs) represents one of the most remarkable advancements in ophthalmology. From their early beginnings to today’s highly sophisticated designs, IOLs have revolutionized the treatment of cataracts and refractive errors. Alongside these advancements, the evolution of IOL power calculation has transformed cataract surgery from a simple vision-restoring procedure into a precise refractive surgery, allowing surgeons to deliver exceptional visual outcomes and reduce patients’ dependence on spectacles [1, 2].
