Evaluation of Corneal Irregular Astigmatism and Visual Quality Following Bilateral Sequential SMILE and LASEK: A Six‐Year Comparative Study

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the corneal spherical component (SC), regular astigmatism (RA), irregular astigmatism (IA, including asymmetry and irregularity), and visual quality 6 years after small incision lenticule extraction (SMILE) and laser subepithelial keratomileusis (LASEK) for mild‐to‐moderate myopia.

Peri-operative intrastromal corneal segmentation after creation of corneal cuts based on laser induced optical breakdown: A perspective study

Journal of the European Optical Society-Rapid Publications
Refractive correction techniques, such as Lenticule Extraction and LASIK, are pivotal in corneal surgery. Precise morphological characterization is essential for identifying post-operative complications, which can be compromised by image noise and low ...

Interocular Differences in Corneal Asphericity Are Associated with Stereopsis in Myopic Astigmatism Candidates for Laser Vision Correction

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To investigate the relationship between stereoacuity and corneal topographic parameters in patients with compound myopic astigmatism who are candidates for laser vision correction (LVC). Methods In this analytical cross‐sectional study, LVC candidates aged 18 years or older with compound myopic astigmatism and corrected distance visual acuity ...

Beyond 20/20: How Laser Eye Surgery Boosts Quality of Life (SMILE vs. FS‐LASIK)

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose Uncorrected refractive errors are the main cause of visual impairment globally and can be corrected with refractive surgeries, such as femtosecond laser–assisted in situ keratomileusis (FS‐LASIK) and small‐incision lenticule extraction (SMILE).

Technique to rescue a retained kerato lenticule using a non-CIRCLE approach

Indian Journal of Ophthalmology. Case Reports
Background: Lenticule extraction is becoming more popular due to its minimally invasive and ocular surface compatible nature. However, retained lenticule is a recognized intraoperative complication of kerato lenticule extraction (KLex) surgeries ...

Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

Advanced Science, Volume 12, Issue 19, May 22, 2025.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...
