**3.6 Procedure**

Proper docking requires cooperation from the patient. The liquid interface has advantages of causing less tissue distortion and minimal increase in intraocular pressure as well as less mean eye movement during capsulotomy. The cornea should be well centered in the patient interface before docking to avoid misalignment of corneal incisions. Apart from the transient learning curve, docking may cause subconjunctival hemorrhage [18]. The estimated incidence of this side effect is 34% and significantly decreased using the liquid interface device with lower suction pressure, and shorter treatment time [19].
