Applications of Anterior Segment Optical Coherence Tomography in Cornea and Ocular Surface Diseases

Journal of Ophthalmology, Volume 2016, Issue 1, 2016., 2016
Optical coherence tomography (OCT) is a noncontact technology that produces high‐resolution cross‐sectional images of ocular tissues. Anterior segment OCT (AS‐OCT) enables the precise visualization of anterior segment structure; thus, it can be used in various corneal and ocular surface disorders.

Evaluation of Corneal Biomechanical Properties Modification after Small Incision Lenticule Extraction Using Scheimpflug‐Based Noncontact Tonometer

BioMed Research International, Volume 2014, Issue 1, 2014., 2014
Purpose. To quantify the effect of small incision lenticule extraction (SMILE) on the corneal biomechanics using Scheimpflug noncontact tonometer (Corvis ST). Methods. Twenty eyes of twenty patients, evaluated as eligible for surgery, with high myopia and/or moderate myopic astigmatism, underwent small incision lenticule extraction (SMILE).

Preservation and Reuse of KLEx Lenticules: From Biobanking to Therapeutic and Refractive Innovations

Bioengineering
Stromal keratophakia was first introduced by Jose Ignacio Barraquer in the 1960s as a refractive procedure involving the implantation of a stromal lenticule into a lamellar keratectomy bed of a recipient cornea.

New instruments for lenticule extraction in small incision lenticule extraction (SMILE).

, 2014
Small incision lenticule extraction (SMILE) is an alternative to Laser-Assisted in situ Keratomileusis (LASIK) for correction of myopia. In cases where surgeons inadvertently dissect the posterior surface first, identification of the anterior surface and

Differences in change of post‐operative antioxidant levels between laser‐assisted lenticule extraction and femtosecond laser in situ keratomileusis

Journal of Cellular and Molecular Medicine, Volume 28, Issue 2, January 2024.
Abstract To evaluate the change of total antioxidant capacity (TAC) and ascorbic acid (AA) between femtosecond laser in situ keratomileusis (FS‐LASIK) and laser‐assisted lenticule extraction (LALEX). A prospective non‐randomized study was conducted, and 33 and 75 eyes that had undergone FS‐LASIK or LALEX surgeries were enrolled, respectively.

Corneal Epithelial Thickness Mapping: A Major Review

Journal of Ophthalmology, Volume 2024, Issue 1, 2024.
The corneal epithelium (CE) is the outermost layer of the cornea with constant turnover, relative stability, remarkable plasticity, and compensatory properties to mask alterations in the underlying stroma. The advent of quantitative imaging modalities capable of producing epithelial thickness mapping (ETM) has made it possible to characterize better ...
