Intraoperative Videokeratography in Penetrating Keratoplasty and Excimer Laser-Assisted Lamellar Keratoplasty for Keratoconus

Abstract

In keratoplasty surgery, videokeratography is useful for suture adjustment. In the PK group, using a double-running suture technique, the postoperative astigmatism (after all sutures were removed) was similar to the astigmatism measured intraoperatively by videokeratography.

Outcome of Keratoconus Management: Review of the Past 20 Years' Contemporary Treatment Modalities

“…101 Also, studies have shown that a cytotoxic level of UVA was reached at the endothelial level with the standard protocol only when the corneal thickness is less than 400 mm, 102 and hence CXL with the standard protocol is recommended in eyes with corneal thickness greater than 400 mm to avoid endothelial cell damage. 103 For thinner corneas, an alternate treatment protocol is recommended 104,105 in which hypo-osmolar riboflavin solution is used to induce corneal swelling before treatment. Corneal thickness is measured before treatment, and instillation of hypo-osmolar riboflavin is continued until the stromal thickness is at least 400 mm.…”

Optical pachymetry–guided custom excimer laser-assisted lamellar keratoplasty for the surgical treatment of keratoconus

“…Finally, the knots were buried and intraoperative suture adjustment was performed. 12 At the end of surgery, the speculum was removed and the eye was patched. The patch was removed the day after the surgery.…”
