Summary

The aim of the study is to present the effect of implanting intrastromal fresh corneal lenticule by SMILE surgery as a new method-approach to correct the corneal shape on purpose to reduce irregular astigmatism and increasing visual acuity after penetrating keratoplasty.

Conditions

  • Irregular Astigmatism

Interventions

DEVICE

Intrastromal Fresh Human Lenticule Implantation

The stromal pocket diameter was set 8.0 mm and cap thickness was set to 140 μm from corneal surface and a 2mm superior incision. Hinge position flap was set at 90°, angle 50° and width 4 mm, side cut angle 90°. The pocket was dissected using a blunt spatula washed with normal saline. The lenticule was held with lenticule forceps and gently inserted into the pocket through the 2 mm superior incision. Incision position changed according to the position of the highest K values.
