Posterior Chamber Phakic Intraocular Lenses for Correcting Ametropia in Stable Keratoconus

Ophthalmic Research
Introduction: The use of posterior chamber phakic intraocular lenses (PCPIOLs) is a reasonable option in the armamentarium to treat refractive error in patients with keratoconus.

Intraocular lens power calculation accuracy in patients with keratoconus: Network meta‐analysis and systematic review

Clinical &Experimental Ophthalmology, Volume 53, Issue 4, Page 356-373, May/June 2025.
Abstract Background Accurate intraocular lens (IOL) calculation in eyes with keratoconus (KCN) poses significant challenges. While various formulas, including KCN‐specific ones, have been investigated, the optimal calculation method remains inconclusive. Methods The study was pre‐registered in PROSPERO (CRD42023483119).

Effect of Anterior Chamber Depth Changes on Corneal Endothelial Cells after Implantable Phakic Lens Implantation in Myopic Patients [PDF]

Al-Azhar International Medical Journal
Background: A phakic intraocular lens (pIOL) is a device that internally corrects the phakic eye's refractive error, reducing or eliminating the need for glasses or contact lenses.Aim and objectives: To determine the impact of anterior chamber depth (ACD)

Effect of Adjuvant Mitomycin‐C on Recurrent Rhegmatogenous Retinal Detachment With Proliferative Vitreoretinopathy Managed by Relaxing Retinotomy and Retinectomy

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
Purpose: To evaluate the role of adjuvant mitomycin‐C (MMC) use in cases of recurrent rhegmatogenous retinal detachment (RRD) complicated by proliferative vitreoretinopathy (PVR) managed by relaxing retinotomy and retinectomy (RR). Methods: A retrospective analysis of consecutive patients undergoing vitreoretinal surgery with RR for RD and PVR was ...

Potential guidelines for cataract surgery and rehabilitation in visually impaired patients: Literature analysis

AGING MEDICINE, Volume 7, Issue 6, Page 802-812, December 2024.
Cataract phacoemulsification combined with the implantation of the most suitable intraocular lens can improve the visual acuity of visually impaired patients. Visual rehabilitation involves special tools such as microperimetry, prisms, lenses, electronic equipment, and specific neuromodulation techniques that stimulate the brain and neuroretina.
