REMINDER OF PARAMETERS INFLUENCING FLAP THICKNESS
Flap thickness depends on several patient-related factors (preoperative corneal thickness, keratometry, IOP, etc...) and surgery-
related factors (hydration, suction time, translation speed, etc ...) :
GENERAL PRINCIPLES
Impact of the preoperative corneal thickness :
• The thinner the cornea, the thinner the flap
• The thicker the cornea, the thicker the flap
Impact of the preoperative keratometry at a given ring :
• The steeper the cornea, the thinner the flap
• The flatter the cornea, the thicker the flap
Impact of the translation speed of the forward microkeratome pass :
• The faster the speed, the thinner the flap
• The slower the speed, the thicker the flap
The variance of these factors have a cumulative effect on flap thickness.
RING & SPEED SELECTION
Moria recommends to follow the ring and speed selection described in the latest version of the M2 and M2SU nomogram.
Use the M2 Single Use heads exclusively with accessories manufactured by Moria for the M2 microkeratome;
use of other accessories can damage the microkeratome and may cause significant patient injuries. Please
read the instruction manual of the Moria M2 microkeratome before use. Available on the web site: moria-
