A comparative fellow-eye prospective study evaluating the efficacy of wavefront-guided VSS VISX CustomVue STAR S4 IR versus the wavefront-optimized WaveLight Allegretto in correction of compound myopic astigmatism

Journal of the Egyptian Ophthalmological Society, 2015
Aim The aim of the present study was to compare the differences in visual outcomes, higher-order aberrations and corneal asphericity, as measured by Q values, in patients undergoing laser in-situ keratomileusis using wavefront-guided variable-spot size ...

Decellularised Corneal Stromal Lamina With or Without Autologous Adipose‐Derived Adult Stem Cells for Advanced Keratoconus: 1‐Year Results of a Phase I/IIa Clinical Trial

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To report the 1‐year clinical outcomes of decellularised human corneal stromal lamina implantation, with or without autologous adipose‐derived adult stem cells (ADASCs), for advanced keratoconus in a European cohort. Methods In this prospective, randomised Phase I/IIa trial, 10 eyes of 10 patients were allocated to decellularised ...

Stem Cell Spheres for Corneal Regeneration

, 2021
Corneal cells isolated from the peripheral cornea and limbus can be cultured in vitro under sphere-forming conditions which enrich for stem and progenitor cells. These stem cell-enriched spheres represent a mixed population of cells comprising epithelial,

Preclinical cataract masquerading as post-LASIK regression

Oman Journal of Ophthalmology, 2016
The purpose of this case report is to bring forth a rare clinical scenario where preclinical cataract mimics post-LASIK regression and to describe the role of aberrometry in detecting higher order aberrations (HOAs) and early lens changes.

Exploring the Impact of Refractive and Ocular Residual Astigmatism on Stereopsis After Photorefractive Keratectomy in Patients With Myopic Astigmatism

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Background To investigate the impact of refractive and ocular residual astigmatism (ORA) on stereopsis after photorefractive keratectomy (PRK) for the correction of myopic astigmatism. Methods This prospective observational study was conducted on patients who underwent PRK for the treatment of myopia and myopic astigmatism using a Schwind Amaris 1050RS

Agreement of anterior corneal aberrations between a Placido-disk-based wavefront analyzer and a Scheimpflug system in myopic candidates for refractive surgery

Photodiagnosis and Photodynamic Therapy
Purpose: We aimed to compare the anterior corneal aberrometry between Pentacam HR, a Scheimpflug-based imaging system, and Peramis, an aberrometer that combines a pyramidal wavefront sensor with Placido-disk topography. Methods: Myopic, otherwise healthy

Arginine depletion as a mechanism for the immune privilege of corneal allografts. [PDF]

, 2011
The cornea is an immune privileged tissue. Since arginase has been found to modulate T-cell function by depleting arginine, we investigated the expression of arginase in the cornea and its possible role in immune privilege using a murine transplant model.
