Comparative study between implantable collamer lens implantation and refractive lens exchange in patients with high myopia

Al-Azhar Assiut Medical Journal
Background and aim While corneal refractive surgery has established visual outcomes, phakic intraocular lenses (PIOLs), such as the implantable collamer lens (ICL), offer a cornea-preserving alternative with high predictability.

Generalized pupil function of a compound X-ray refractive lens [PDF]

, 2017
Quality of a refractive compound X-ray lens can be limited by imperfections in surfaces of unit lenses and stacking precision. In general case both the lens transmission and optical aberrations define properties of a beam in the lens exit plane; together
