Visual and refractive outcomes after SMILE versus FS-LASIK: a paired-eye study.

Objective: To compare visual acuity, refraction, Schirmer test, tear break-up time (TBUT), esthesiometry, optical quality, higher order aberrations and posterior corneal elevation measurements before and after small-incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK).

Method: Paired eye, randomized, cohort study. Follow-up was performed at days 1 and 7, and at months 1, 3, 6 and 12.

Increased Expression of TLR4 in Circulating CD4+T Cells in Patients with Allergic Conjunctivitis and In Vitro Attenuation of Th2 Inflammatory Response by Alpha-MSH.

Ocular allergic diseases are frequently seen in ophthalmological clinical practice. Immunological damage is mediated by a local Th2 inflammatory microenvironment, accompanied by changes in circulating cell subsets, with more effector cells and fewer T regulatory cells (Tregs). This study aimed to evaluate the involvement of toll-like receptor 4 (TLR4) and α-melanocyte stimulating hormone (α-MSH) in the immune regulation associated with perennial allergic conjunctivitis (PAC).

Short-Term Results Analysis in the Allogenic Transplantation of Limbal Stem Cells Expanded on Amniotic Membrane in Patients with Bilateral Limbal Stem Cell Deficiency.

The objective of this study was to describe the short-term results of allogenic transplantation of limbal stem cells expanded on amniotic membrane for the ocular surface reconstruction. Prospective nonrandomized, nonmasked study in a single ophthalmological center. Ten patients with bilateral total limbal stem cell deficiency (LSCD) were included.

Systemic Immunosuppression for Limbal Allograft and Allogenic Limbal Epithelial Cell Transplantation.

Bilateral limbal stem cell deficiency (LSCD) treatment requires the need to obtain allogenic limbal tissue for transplantation. Outcomes of different surgical techniques depend on multiple factors, including the underlying etiology, ocular surface, eyelid status and used surgical intervention. Some of the management options for bilateral LSCD include cadaveric, living related or living non-related conjunctival limbal allograft (CLAL), keratolimbal allograft (KLAL), allogenic cultured limbal epithelial transplantation (CLET) and allogenic simple limbal epithelial transplantation (SLET).

Practice Patterns in the Management of Primary Pterygium: A Survey Study.

Purpose: To characterize cornea specialists' current practice preferences in the management of primary pterygium.

Methods: A 25-item survey regarding indications for surgery, surgical technique, use of adjuvant therapy, type and duration of postoperative therapy, and treatment of early recurrences was designed and sent to members of the Cornea Society through the kera-net listserv.

Results: In total, 199 cornea specialists completed the questionnaire.
