Abstract Details

Purpose:

to Describe a rare intra-operative complication of vertical gas breakthrough due to epithelial folds during Ducking stage in intralase Lasik treatment .

Setting:

Optimax Laser Clinics UK

Methods:

We observe and report four cases of four eyes of Vertical gas breakthrough during intralase Lasik due to epithelial folds and wrinkles during the Ducking stage of intralase treatment . these all four eyes were in males aged between 54 to 60 years old , pre lasik eye examination did not find any corneal or epithelial pathology in all these 4 eyes ,

Results:

In 3 eyes the vertical break through was limited to 2X2 mm size at the peripheral side of the flaps , lifting the flaps were difficult at these areas and produced peripheral but small button hole , however laser ablation was completed and all these eyes obtained 20/20 vision next day without any complications . in one eye the epithelial folds were central and large at 3X4 mm, which gave large central vertical gas breakthrough, flap was not lifted and Lasek treatment was performed , patient obtained 20/20 vision one week after Lasek without complications

Conclusions:

Epithelial folds and wrinkles during Ducking stage of intralase may produce Vertical gas breakthrough , which can be small and peripheral so Lasik can be completed without complications , or can be central and large so flap should not be lifted and treatment should be changed to Lasek.
