With improving surgical technique and equipment, the acceptable age for placing an intraocular lens in infants and children is becoming younger. The tools for predicting intraocular lens power have not necessarily kept up, as current theoretical and regression intraocular lens power prediction formulas are largely based on adult eyes at axial lengths, anterior chamber depth, and keratometric values much different than those seen in infants. In addition, the adult eye has matured and is no longer growing, whereas the eyes of infants and children may continue to note changes in axial length, keratometric values, and possibly optical characteristics. Another source of error in intraocular lens power selection that is more likely to occur in pediatric patients than in adult patients is inaccuracy in measurement of axial length or keratometric power. A review of current tools and considerations for intraocular lens power prediction in infants and children is presented.

Femtosecond Laser Arcuate Keratotomy vs Toric Intraocular Lens Implantation in Cataract Surgery: A Randomized Clinical Trial.
JAMA Ophthalmol
January 2025
Eye Center, The Second Affiliated Hospital, School of Medicine, Zhejiang University, Zhejiang Provincial Key Laboratory of Ophthalmology, Zhejiang Provincial Clinical Research Center for Eye Diseases, Zhejiang Provincial Engineering Institute on Eye Diseases, Hangzhou, China.
Importance: After cataract surgery, postoperative residual astigmatism can influence a patient's visual quality and satisfaction. Finding ways to minimize this astigmatism is important.
Objective: To compare the clinical outcomes of femtosecond laser arcuate keratotomy (FSAK) and toric intraocular lens (TIOL) implantation for astigmatism correction in patients undergoing femtosecond laser-assisted cataract surgery.
Anterior chamber morphological and refractive outcomes following phacoemulsification in pseudoexfoliative eyes: A case-control study.
Eur J Ophthalmol
January 2025
Ophthalmology Department, ULS São José, Lisboa, Portugal.
Purpose: To compare changes in angle morphology, anterior chamber depth (ACD) and refractive prediction error (PE) after phacoemulsification between pseudoexfoliative (PEX) and non-PEX eyes.
Methods: Prospective case-control study of eyes submitted to cataract surgery. Biometric data and angle parameters - Anterior Chamber Angle (ACA), Angle Opening Distance (AOD), Scleral Spur Angles (SSA) and Trabecular Iris Space Area (TISA) - were measured preoperatively and 1-month postoperatively through swept-source anterior segment optical coherence tomography.
An analysis of heavy silicone oil treatment for inferior proliferative vitreoretinopathy.
BMC Ophthalmol
January 2025
Oxford Eye Hospital, Oxford University Hospitals NHS Foundation Trust, Oxford, UK.
Purpose: Proliferative vitreoretinopathy (PVR) is a complication of retinal detachment which requires multiple vitreoretinal surgical interventions and frequent use of oil endotamponade. In this study, we conducted an in-depth analysis of complications associated with the use of heavy silicone oil in the management of inferior PVR.
Methods: A retrospective cohort study of 20 eyes that underwent vitrectomy for inferior PVR with use of heavy silicone oil (Densiron 68) between March 2021 and October 2022 at Oxford Eye Hospital.
Purpose: The light adjustable lens (LAL) (RxSight, Aliso Viejo, CA) is a premium intraocular lens that allows for correction of residual refractive error and astigmatism following implantation. Herein, we describe the surgical approach and evaluate the visual outcomes of patients following scleral fixation of the LAL.
Methods: Retrospective, single-surgeon surgical case series of 3 patients (3 eyes) with intraocular lens complications, who underwent combined pars plana vitrectomy and sutureless needle assisted intrascleral haptic fixation of the LAL between April 2022, to August 2023.
Simplified Technique for Correcting Intraocular Lens Decentration in Scleral-Sutured Fixation Surgery.
Retina
January 2025
Department of Ophthalmology and Vision Science, Eye and ENT Hospital, Fudan University, Shanghai 200031, People's Republic of China.
Purpose: To describe a simplified technique for correcting intraocular lens (IOL) decentration during scleral-sutured IOL fixation surgery.
Methods: During surgery, Purkinje images were utilized to assess IOL positioning. A straightforward IOL decentration adjustment technique was employed when necessary.
