Clinical Ocular Biomechanics: Where Are We after 20 Years of Progress?

Phillip T. Yuhas et al.

Summary: Ocular biomechanics plays an important role in assessing the response of eye structures to forces and its relevance to disease development and treatment. This review introduces the basic principles and terminology of ocular biomechanics, and highlights studies on keratoconus, laser refractive surgery, and glaucoma.

In-vivo high-speed biomechanical imaging of the cornea using Corvis ST and digital image correlation

Bo Wang et al.

Summary: In-vivo corneal biomechanical characterization is important for the diagnosis of eye disorders. The study used an air-puff tonometer to analyze the dynamic deformation of the cornea and found differences in the biomechanical properties between normal and keratoconus groups. The study also reconstructed the high-speed displacement, strain, velocity, and strain rate fields of the cornea at a tissue level.

Effect of travoprost, latanoprost and bimatoprost PGF2α treatments on the biomechanical properties of in-vivo rabbit cornea

JunJie Wang et al.

Summary: This study found that PGF2 alpha analogues can cause corneal softening and changes in the extracellular matrix, leading to reduced accuracy in measuring intraocular pressure (IOP). Different types of PGF2 alpha were associated with varying degrees of tissue stiffness reduction and corneal microstructure changes. These changes may result in an overestimation of the effectiveness of PGF2 alpha in lowering IOP, creating uncertainties in glaucoma management.

Reliability analysis of successive Corneal Visualization Scheimpflug Technology measurements in different keratoconus stages

Elias Flockerzi et al.

Summary: This study evaluates the reliability of corneal biomechanical response measurements using the Corneal Visualization Scheimpflug Technology (CST) in different stages of keratoconus. Results show that parameters such as Ambrosio relational thickness and SPA1 vary significantly between control group and KC patients, while other parameters show differences among different stages of KC. All parameters are highly reliable, with corneal tomography remaining unaffected.

Evaluation of Corneal Biomechanical Indices in Distinguishing Between Normal, Very Asymmetric, and Bilateral Keratoconic Eyes

Robert Herber et al.

Summary: This study aimed to evaluate the ability of biomechanical indices provided by the Ocular Response Analyzer and dynamic Scheimpflug analyzer to distinguish between normal eyes and eyes with very asymmetric ectasia and keratoconus. The results showed that the Corvis Biomechanical Index had the highest diagnostic ability in distinguishing different subgroups of ectatic eyes.

Enhanced Diagnostics for Corneal Ectatic Diseases: The Whats, the Whys, and the Hows

Louise Pellegrino Gomes Esporcatte et al.

Summary: Different diagnostic strategies are needed for patients with ectatic corneal diseases (ECDs), including screening, confirmation of diagnosis, classification, severity staging, prognostic assessment, and clinical follow-up. These strategies enable personalized treatments and are crucial for identifying high-risk patients and improving diagnostics.

Application of a scheimpflug-based biomechanical analyser and tomography in the early detection of subclinical keratoconus in chinese patients

Yan Liu et al.

Summary: The combination of a Scheimpflug-based biomechanical analyser and tomography could increase the accuracy in detecting subclinical keratoconus in Chinese patients. The tomographic and biomechanical index (TBI) was the most valuable index for detecting subclinical keratoconus, with a high sensitivity and specificity. Evaluation of corneal biomechanical properties in refractive surgery candidates could be helpful for recognizing potential keratoconic eyes and increasing surgical safety.

Corneal transplantation for keratoconus in South Korea

Sungsoon Hwang et al.

Summary: This study found that the incidence rate of corneal transplantation in patients with keratoconus was relatively low in South Korea compared to other countries. Male sex, severe atopic dermatitis, obstructive sleep apnea, and intellectual disability were significantly associated with an increased risk of progression to corneal transplantation in patients with keratoconus.
