Optical correction of aphakia

Optical correction of aphakia refers to various interventions to restore vision in patients lacking the natural lens of the eye, most commonly due to surgical removal (such as cataract extraction), trauma, or congenital absence[1][3][4]. Correction methods include thick high-plus glasses (rarely used, especially in children due to poor optics and cosmetic/social drawbacks), specialized contact lenses (rigid gas-permeable, silicone elastomer, hydrogel), and intraocular lens (IOL) implantation[4][5][6][7][8]. IOL implantation is often preferred for permanent correction in adults, while contact lenses are frequently used in infants and children because of developmental concerns and surgical limitations[6][7]. Each intervention has distinct optical and safety profiles, and patient selection and ongoing management are critical for effective rehabilitation and minimizing complications[7][8].
