Gastrointestinal cancer (GIC) remains a leading cause of morbidity and mortality worldwide. Unfortunately, these cancers are diagnosed in advanced metastatic stages due to lack of reliable biomarkers that are sufficiently specific and sensitive in early disease. There has been growing evidence that circulating exosomes can be used to diagnose cancer non-invasively with limited risks and side effects.

Methods: We reviewed 112 myopic eyes undergoing PIOL implantation using Artisan (40 eyes), Artiflex (36 eyes), and implantable collamer lens (ICL, 36 eyes). Best corrected visual acuity (BCVA), intraocular pressure (IOP), pachymetry, corneal endothelial cell (CEC) loss, and higher order aberrations (HOA) were compared.
Article Synopsis
- The study aimed to assess the biomechanical properties of corneal grafts in keratoconus patients who underwent penetrating keratoplasty (PKP) using the ocular response analyzer (ORA).
- It analyzed data from 34 patients, measuring factors like corneal hysteresis (CH) and corneal resistance factor (CRF) at least six months post-surgery, and examined the impact of donor-recipient size differences and graft thickness.
- Results indicated that larger graft sizes and greater donor-recipient disparity lead to better biomechanical properties, with significant correlations found between these factors and intraocular pressure measurements post-PKP.
Purpose: To compare biomechanical properties of transplanted corneas after penetrating keratoplasty (PK) with those after deep anterior lamellar keratoplasty (DALK) using Anwar's big-bubble technique.
Materials And Methods: This cross-sectional comparative study consisted of 45 PK eyes (group 1) and 23 DALK eyes (group 2) with the underlying pathology of keratoconus. The Ocular Response Analyzer was used to measure Goldmann-correlated intraocular pressure (IOPg) and cornea-compensated IOP (IOPcc), as well as graft biomechanical properties, namely corneal hysteresis (CH) and corneal resistance factor (CRF).
Purpose: To compare intraocular pressure (IOP) measured using the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Buffalo, NY) with that measured using the Goldmann applanation tonometer (GAT) in keratoconic eyes after deep anterior lamellar keratoplasty (DALK) and evaluate the influence of central graft thickness (CGT), corneal astigmatism, corneal hysteresis (CH), and corneal resistance factor (CRF) on the IOP measurements.
Methods: IOP using the GAT (IOP(GAT)), CH, CRF, Goldmann-correlated IOP (IOP(g)), cornea-compensated IOP (IOP(cc)) using the ORA, and CGT were measured in 23 keratoconic eyes undergoing DALK. Bland-Altman plots were used to evaluate agreement between the tonometers.
