FLAP BUTTONHOLE
My K value of right eye is 48 and left eye is 46.2. Right eye CCT is 582 and left eye CCT is 576. 4 months ago the K values were 47.7 and 46.0 respectively. Dr. JS Tatiyal, Prof. AIIMS, Delhi, examined my report and declared me FIT for Femtosecond lasik. He said I have no progression of keratoconus though my corneas are borderline steep.
Right eye -4.00 -2.75*170°
Left eye -6.00 -2.5*170°
Fundus and other pentacam readings are normal.
After lasik corneal thickness will be
Right eye 350
Right eye 390
Are these corneal thickness still safe or will it make corneal too thin? ( Ectasia)?
I want to know is Femtosecond lasik uses microkeratocome (tool) for flap cutting or is it BLADELESS?.
I am afraid of developing buttonhole flaps due to borderline steepness of my corneas. Chances of developing buttonhole flaps?
Please help

Hello
A. This corneal thickness is good...minimum stromal bed is usually 250 micron along with 90 micron thick flap..meaning 340 micron post Lasik is good enough...as you will have 390 micron so this is good thickness
B. Femtosecond laser does not use microkeratome....it is blade less
C. Chances of button hole with femtosecond laser is approximately NIL
