Phakic intraocular Lens implantation in keratoconus patients

European Journal of Ophthalmology, 2023
Background Both the anterior chamber and posterior chamber phakic intraocular lenses (pIOLs) implantation are acceptable refractive surgical approaches in keratoconus patients with high anisometropia, contact lens intolerance, or who prefer spectacle and contact lens independent.

Phakic Intraocular Lens in Keratoconus

2021
Keratoconus remains a significant cause of blindness worldwide. Despite advances in slowing the progression of keratoconus, addressing residual refractive error remains challenging. The introduction of phakic intraocular lenses allows the option of a reversible procedure that maintains accommodation.

Phakic intraocular lens implantation for the correction of hyperopia

Journal of Cataract and Refractive Surgery, 2019
The prevalence of myopia is much higher than hyperopia. Hence, there are relatively few studies investigating phakic intraocular lens (pIOL) implantation for the correction of hyperopia. This review aimed to summarize the available relevant literature on the efficacy and safety of pIOL implantation for the correction of hyperopia and hyperopic ...
