Introduction: We report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual outcomes in eyes with implantable collamer lens-induced cataract and astigmatism.
Case Presentation: A 53-year-old woman had undergone toric implantable collamer lens implantation three years earlier. After informed consent was obtained, we performed simultaneous toric implantable collamer lens removal and phacoemulsification with toric intraocular lens implantation. Preoperatively, the manifest refraction was 0, -0.5 × 15, with an uncorrected visual acuity of 0.7 and a best spectacle-corrected visual acuity of 0.8. Postoperatively, the manifest refraction was improved to 0, -0.5 × 180, with an uncorrected visual acuity of 1.2 and a best spectacle-corrected visual acuity of 1.5. No vision-threatening complications were observed.
Conclusion: Toric intraocular lens implantation may be a good surgical option for the correction of spherical and cylindrical errors in eyes with implantable collamer lens-induced cataract and astigmatism.

This laboratory study aims to assess the effects of misaligning different trifocal intraocular lenses (IOLs) under varying spectral and corneal spherical aberration (SA) conditions. With an IOL metrology device under monochromatic and polychromatic conditions, the following models were studied: AT ELANA 841P, AT LISA Tri 839MP, FineVision HP POD F, Acrysof IQ PanOptix, and Tecnis Synergy ZFR00V. The SA was simulated using an aberration-free and average-SA cornea.

Purpose: To identify the minimally required number of distances of visual acuity (VA) measurements for the reliable estimation of the visual acuity curve (VAC) and area of the curve (AoC) in presbyopia correction.
Patients And Methods: The study was divided into a validation and a clinical phase with a total recruitment of 120 participants (120 eyes) who underwent uncomplicated pseudophakic presbyopia surgery with bilateral premium intraocular lenses (IOL) implantation. This study was conducted in the Department of Ophthalmology, University Hospital of Alexandroupolis, Alexandroupolis, Greece.

Introduction: Implantable collamer lens (ICL) is a posterior chamber phakic intraocular lens. It is usually indicated for high refractive error correction that cannot be treated by laser vision correction due to physical limitations.
Case Presentation: 39 years old male with a past ocular history of keratoconus underwent astigmatic keratotomy followed by crosslinking in both eyes a couple of years later due to signs of corneal ectasia progression.

Department of Ophthalmology, the First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan, China.
Purpose: The research investigates the efficacy of hydroxypropyl methylcellulose (HPMC) treatment in facilitating the development of compact water droplets on the rear surface of synthetic lenses with capsule imperfections during the process of fluid-air exchange.
Method: This study examined four patients with intraocular lens (IOL) implants and posterior capsule defects who experienced the formation of dense water droplets on the posterior surface following fluid-air exchange. When this occurrence obstructs fundus visualization during surgery, it is recommended to suspend the surgical procedure.
Purpose: To evaluate dynamic changes in ciliary parameters and Implantable Collamer Lens V4C (ICL) (STAAR Surgical) haptic position using mydriatic and miotic agents and their effects on the central and peripheral vault.
Methods: This study involved 80 eyes from 40 consecutive patients (mean age: 28.05 years; range: 19 to 42 years) examined 3 months after ICL implantation.
