Faint epithelial ingrowth

PurposePurpose

　　 To compare the epithelial ingrowth rates after lifted previous flap which by microkeratomic and Intralased.

MethodsMethods

　　 The enhancement procedure was done after Lasik with microkeratome (M group) (Moria, France) or with femtosecond laser (Fs group) (Intralase FS60, AMO, US). This series included 537eyes from 309 patients, age ranged from 22 to 68 yrs. All of the case (M 315 eyes & Fs 222 ） was re-treated as lifting the original flap with spatula and the enhancement followed without any complication by the same surgeon(author).

ResultsResults　　 There is shown as next slide that faint or band s

haped epithelial mass accumulated under the flap in 45 eyes (14.3%) in M group and 11 eyes (4.95%) Fs group.

When the severe ingrowth seen toward the central cornea, they needed doing the mechanical removal as a re-re-treatment in M group 7 eyes (15.6%), compared to Fs group none (0%).

Intralased flap Microkeratomic flap

ConclusionsConclusions

　 The Intralased flap has lower epithelial ingrowth rates than that by microkeratome. We believe using IntraLase as a flap creator would be better option.
