Dynamic assessment of variations in pupil diameter using swept-source anterior segment optical coherence tomography after phakic collamer lens implantation.

Purpose: To dynamically assess variations in pupil diameter induced by changes in brightness in myopic eyes implanted with an implantable collamer lens (ICL, STAAR Surgical) with a central port.

Methods: This prospective, observational single-center case series study comprised 65 eyes from 65 consecutive patients undergoing ICL implant. A modified commercially available swept-source Fourier-domain anterior segment optical coherence tomography (AS-OCT) device was used for imaging and performing dynamic pupillometry under changing light conditions before and after a mean follow-up interval of four months after surgery.

Bilateral Refractive Lens Exchange With Trifocal Intraocular Lens for Hyperopia in Patients Younger Than 40 Years: A Case-Control Study.

Purpose: To evaluate visual outcomes, satisfaction, and spectacle independence in non-presbyopic hyperopic patients who underwent bilateral refractive lens exchange with a trifocal intraocular lens (IOL) and to compare them with presbyopic hyperopic patients.

Methods: In this retrospective study, patients younger than 40 years underwent bilateral refractive lens exchange with a diffractive trifocal IOL (FineVision Micro F; PhysIOL SA) for hyperopia with at least 3 months of follow-up. A control group of patients older than 50 years was matched by axial length, sex, and follow-up.

Case Report: Double Intrastromal Corneal Ring Segment and Posterior Chamber Phakic Intraocular Lens Implantation.

Significance: Keratoconus can manifest asymmetrically, affecting binocularity and becoming a refractive problem that is sometimes complex to solve. We propose a therapeutic approach for correction of keratoconus based on parallel implantation of a second intrastromal corneal ring segment (ICRS).

Purpose: This study aimed to improve the refractive status of a patient affected with advanced bilateral keratoconus using implantation of a second ICRS and a phakic intraocular lens.

Long-term assessment of crystalline lens transparency in eyes implanted with a central-hole phakic collamer lens developing low postoperative vault.

Purpose: To assess long-term crystalline lens transparency in eyes implanted with phakic collamer intraocular lens (pIOL) with a central port and low postoperative vault for correction of myopia.

Setting: Clinica Baviera, Madrid, Spain.

Design: Retrospective cross-sectional single-center study.

Comparison of visual outcomes and flap morphology using 2 femtosecond-laser platforms.

Purpose: To compare the 3-month postoperative refractive results and flap thickness homogeneity after correction of myopia using the Intralase femtosecond platform and the Victus dual femtosecond laser platform.

Setting: Novovision Clinic, Madrid, Spain.

Design: Prospective case series.
