Influence of Biometric and Corneal Tomographic Parameters on Normative Corneal Aberrations Measured by Root Mean Square.

: To determine the impact of corneal and biometry parameters on the normative root mean square (RMS) values of corneal aberrations measured at a 6 mm diameter. : The RMS values for corneal aberrations (anterior, posterior, and total) were measured along with corneal parameters using Scheimpflug tomography on 770 normal subjects. The biometric parameters were measured with an optical biometer.

The Clinical Usefulness of Evaluating the Lens and Intraocular Lenses Using Optical Coherence Tomography: An Updated Literature Review.

The Lens Dysfunction Syndrome includes two widespread ocular disorders: presbyopia and cataract. Understanding its etiology, onset, progression, impact, prevention, and treatment remains a significant scientific challenge. The lens is a fundamental structure of the ocular dioptric system that allows for focus adjustment or accommodation to view objects at different distances.

Severe epithelial ingrowth after pars plana vitrectomy ten years after LASIK relifting.

Epithelial ingrowth is one of the most significant complications of Laser in Situ Keratomileusis (LASIK) refractive surgery. We present the case of a 72-year-old male with a history of myopic LASIK (1999), who underwent cataract surgery and a second thin LASIK sub-Bowman flap to correct refractive error. Then, three months after pars plana vitrectomy for an epiretinal membrane, the patient complained of progressive vision loss.

Assessment of the ciliary muscle and scleral anterior thickness in high myopia by optical coherence tomography.

Purpose: To assess ciliary muscle (CM) and anterior scleral thickness (AST) dimensions in vivo in high myopia using swept-source optical coherence tomography (SS-OCT) and to compare with emmetropic and hyperopic subjects.

Methods: Cross-sectional study that included 34 high myopic patients (≥ -6 diopters [D]), 90 emmetropes (-1 to +1 D) and 38 hyperopic patients (≥ +3.5 D).
