Accuracy of Toric Intraocular Lens Implantation Using Three‐Random‐Point Marking Method: A Prospective Pilot Study [PDF]

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Introduction This study aimed to compare the accuracy of three‐random‐point (TRP) marking method with the slit‐lamp horizontal meridian (SHM) marking method by using an image‐guided system in the positioning of a toric intraocular lens (IOL). Materials and Methods A total of 60 eyes of 54 patients who underwent cataract surgery were prospectively ...

Clinical evaluation of toric intraocular lens implantation based on iTrace wavefront keratometric astigmatism

BMC Ophthalmology, 2020
Background Currently, there is no standard technique for determining corneal astigmatism. The iTrace wavefront aberrometry of cornea calculated steep power and axis based on the best Zernike mathematical fit from all topo data within 4 mm circle.

Study of Visual Quality and Higher Order Aberrations in Early Posterior Capsular Opacification [PDF]

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.
Purpose: This study aims to explore the visual quality and characteristics of higher order aberrations (HOAs) in patients with early posterior capsule opacification (PCO), providing a theoretical basis for the clinical assessment of early PCO and the potential benefits of Nd:YAG posterior capsulotomy.
