The first intraocular lens was implanted by Harold Ridley in 1949. The English ophthalmologist placed a disk-shaped lens made of PMMA inside the posterior chamber of a 45-year-old woman’s eye after a cataract surgery. Of course, developing complications such as glaucoma, uveitis and lens dislocation stopped him from designing these lenses. Since then, ophthalmologists have always been looking for more appropriate lenses in terms of tissue compatibility, lower posterior capsule opacification (PCO) rates and better visual acuity for patients. Today, with the advancement of technology, intraocular lenses have also improved and become more complicated. For instance, special lenses such as blue-light filtering lenses, aspheric lenses, multifocal lenses, and toric lenses have been developed, each to meet the needs of a large group of patients.
