Understanding and minimizing the biomechanical effects of LASIK surgery can optimize the predictability of outcomes. The biomechanical shifts caused with flap creation appear to be more controllable with a uniform thickness flap that can be created using a femtosecond laser.

The cornea functions as a mechanical barrier to injury and a transparent scaffold for the eye's primary refracting surface, the tear film. The material properties of the cornea are integral to each of these functions and impact its response to disease and surgery. To better ascertain the relevance of these properties in clinical ophthalmology, techniques that are capable of characterizing material behavior in a nondestructive fashion are needed.

Imaging the anterior segment has improved dramatically in recent years. The benefits of these refinements are clear and have led to their broad adoption in clinical practice. But what is the  cost of complexity? The idiosyncrasies of each refinement influence the output, and as layers are added, we are less likely to appreciate the ‘‘wrinkles’’ that each contributes.

The biomechanical and wound healing properties of the cornea undermine the predictability and stability of refractive surgery and contribute to discrepancies between attempted and achieved visual outcomes after LASIK, surface ablation and other keratorefractive procedures. Surgical and disease models that integrate corneal geometric data, substructural anatomy, elastic and viscoelastic material properties and wound healing behavior have the potential to improve clinical outcomes and minimize complications but depend on the identification of preoperative predictors of biomechanical and wound healing responses in individual patients.

Check out one of our groups orignal papers. It's an excellent primer on the biomechanical properties of the cornea and how their sub-optimal manifestations can lead to corneal ectasia.

Refractive surgeons can now perform a highly precise workup prior to surgery—and thanks to developments such as wavefront technology, they can deliver highly precise treatment. But how can the preoperative testing and treatment be better linked?

Advances in Corneal Biomechanics
Watch Dr. Dupps explain newer methods of assessing both pre and post-crosslinked corneas as well as a sneak peak into what we have in development. Current diagnostic technologies include air puff devices like the Ocular Response Analyzer and Corvis ST. Emerging techniques include OCT based elastography and Brillouin Microscopy.

Experimental Eye Research
Abstract: Studies suggest that standard corneal collagen crosslinking (CXL) is a safe and effective treatment to stiffen the cornea for keratoconus and other ectatic corneal disorders. The purpose of the present study was to compare the biomechanical effects of transepithelial benzalkonium chloride-EDTA (BAC-EDTAriboflavin-UVA crosslinking to standard epithelium-off riboflavin-UVA crosslinking in a rabbit model.

PURPOSE: To test the hypothesis that spatially selective corneal stromal stiffening can alter corneal astigmatism and assess the effects of treatment orientation, pattern, and material model complexity in computational models using patient-specific geometries.

What tool or method is best for diagnosing keratoconus?

I think it is important to begin by stipulating that no currently available tool for diagnosing keratoconus provides a complete view of the disease state.

PURPOSE: To compare the biological effects of ribofl avinultraviolet A (UVA) corneal cross-linking (CXL) performed with a traditional epithelium-off method to several transepithelial methods in a rabbit model. Preliminary experiments on biomechanical rigidity were also performed.

The material properties of the cornea are important determinants of corneal shape and refractive power.

The purpose of this study was to develop a 3D patient-specific finite element model (FEM) of the cornea and sclera to compare predicted and in vivo refractive outcomes and to estimate the corneal elastic property changes associated with each procedure.

This modeling study demonstrated that differences in the corneoscleral stiffness relationship may be a source of individual variation in refractive surgery outcomes.
