“…The apex of the cone extends up to approximately 60% of the stroma. 31 There are few well-controlled LTK studies in the literature. LTK has been used to correct hyperopia up to 4.00D and has shown some initial promising results in the correction of low hyperopia.…”

“…LTK has been used to correct hyperopia up to 4.00D and has shown some initial promising results in the correction of low hyperopia. 31 However, it has been associated with induced irregular astigmatism and a significant regression rate. [31][32][33] Alió et al 33 reported a regression rate of 31% after six months.…”

“…This produces a cylindrical footprint that extends approximately to 80% of the depth of the peripheral cornea. 31,34 Deep penetration is desirable and necessary to minimise regression, because permanent collagen contraction is dependent on achieving a consistent deep zone of collagen shrinkage. 35 A probe is used to create eight to 32 points in a ring pattern at 6, 7 or 8mm optical zones.…”

Refractive surgery has become the most rapidly developing field in ophthalmology over the last two decades. Several modern refractive procedures have become available over the last 10 years including phakic intraocular lenses (pIOLs), epithelial laser-assistedin situkeratomileusis (epi-LASIK), wavefront-guided (WG) laser treatments and a few others. Laser and non-laser refractive surgical procedures are currently used to address refractive errors. No single procedure works best for everyone; each one has its own set of advantages and disadvantages. Careful patient selection is the key for optimum visual outcomes. Treatment algorithms have been refined over the years, improving accuracy. Laser technology and delivery platforms are under continuous improvement, leading to increasingly precise results. Further modifications and refinements are ongoing, offering expanding surgical options in this rapidly evolving field.

“…In this procedure, radiofrequency current is delivered into the cornea through fine conducting tips ͑keratoplast tips͒ that are arranged at the corneal periphery. 14,15 Due to the heat generated by passing a current through the cornea, collagen lamellae in the area surrounding the tip shrink in a controlled fashion to form a column of denatured collagen. 16 The alteration of corneal architecture can then lead to vision correction for presbyopic and hyperopic patients.…”

Ex vivo multiphoton imaging is used to characterize rabbit corneal wound healing after conductive keratoplasty (CK) procedures. CK is performed on the right eyes from eight New Zealand albino rabbits while the left eyes are punctured by a keratoplast tip without energy application. Rabbits are humanely sacrificed 1 day, 1, 2, and 4 weeks after the CK procedure. Eye balls are enucleated and placed on the microscope for multiphoton imaging. Multiphoton imaging reveals damage of corneal epithelium and stroma caused by the CK procedure and the subsequent wound healing process can be followed without histological procedures. Multiphoton excited autofluorescence images demonstrate that re-epithelilialization is accomplished within 1 week in both CK and control groups. However, epithelial hyperplasia is observed in CK corneas. In addition, stromal wounds in the control group become inconspicuous within 1 week while obvious wounds still exist in CK corneas for at least 4 weeks. Postconductive keratoplasty corneal damage and wound healing can be characterized by multiphoton microscopy without histological procedures. Our results suggest that multiphoton microscopy has potential in the clinical evaluation of corneal damage due to refractive surgery, and can be used to study and reduce the unwanted side effects of these procedures.

“…21,22,[24][25][26]28 The use of global pachymetry is increasingly relevant in this age of customized corneal ablation 31,32 and conductive keratoplasty. 33,34 In this study, we look beyond the central corneal pachymetry and examine the repeatability and variability of Orbscan global pachymetry throughout the measured cornea.…”
