Phacoemulsification Associated Corneal Damage Evaluated by Corneal Volume

Intrasession and intersession repeatability of the Pentacam system on posterior corneal assessment in the normal human eye

“…Our previous study 18 using the Pentacam system found that taking 3 consecutive readings to generate a mean corneal thickness should provide high precision for topographic corneal thickness between 2 sessions. Suzuki et al 19 encountered the same problem and proposed using the corneal volume for analysis. We found almost identical corneal volume at different zone diameters between visits.…”

“…Statistically, it is difficult to investigate the topographic corneal thickness. Suzuki et al 19 suggest using the corneal volume generated by the Pentacam for comparison. The Pentacam has a default setting providing corneal volume at the 3.0 mm, 5.0 mm, and 10 mm zones.…”

Early changes in corneal edema following torsional phacoemulsification using anterior segment optical coherence tomography and Scheimpflug photography

“…Therefore, based on the central corneal thickness and specular microscopy alone, the data needed for determining the degree of corneal edema following phacoemulsification are insufficient. Suzuki et al [20] used Pentacam Scheimpflug imaging to assess phacoemulsification-associated entire corneal damage. In the present study, we also used the Pentacam Scheimpflug camera and added an analysis of corneal morphology.…”

Intraoperative performance and postoperative outcomes of microcoaxial phacoemulsification

“…9 Alterations in the endothelial cell count indicate the safety of the surgical technique in terms of energy dissipation, instrumentation, flying nuclear fragments in the chamber, and type and amount of fluid used. [30][31][32][33][34] In addition to ECD, we evaluated the CV because it reflects cell shape and is a good indicator of endothelial damage. Reporting hexagonality would have provided additional information.…”
