Central island treatment using Technolas 217 based on Orbscan II assessment.
OBJECTIVE
To present a case of central island after myopic laser in situ keratomileusis and the treatment technique using Technolas 217 laser based on topography findings.


METHODS
Serial corneal topographies with Orbscan were taken and an ablation profile was generated with subsequent treatment using the phototherapeutic keratectomy mode and surface ablation technique.


RESULTS
Marked reduction was noted in the height of central island and the best spectacle-corrected visual acuity improved from 20/40 to 20/25.


CONCLUSIONS
Ablation profile based on corneal topography can provide a possible treatment option for patients with central island.
