Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Biomaterials Science

Background:

  • Precise trepanation is critical for successful keratoplasty.
  • Existing trephining methods may have limitations in achieving exact cutting margins.

Purpose of the Study:

  • To evaluate a novel suction trephine for keratoplasty.
  • To assess the quality of cutting margins produced by the new device.
  • To report initial clinical outcomes of its use.

Main Methods:

  • A new suction trephine was utilized in keratoplasty procedures.
  • Cutting margins were examined using scanning electron microscopy (SEM).
  • Clinical results were observed in a cohort of 25 patients.

Main Results:

  • The suction trephine produced exact and sharp cutting margins.
  • SEM analysis confirmed the quality of the trephine cuts.
  • Initial clinical observations in 25 cases were favorable.

Conclusions:

  • The novel suction trephine facilitates precise trepanation for keratoplasty.
  • The device yields high-quality cutting margins, as confirmed by SEM.
  • Early clinical data suggest good outcomes, warranting further investigation.
