Use of Simultaneous Bilateral Cataract Surgery (SBCS) to Optimize Parameters Affecting the Subjective Perception of the Procedure

Table 3

Comparison of perception of time of surgery in the control subgroup (without change of any parameter between right and left eye): mean ± SD; values of paired t-test between right and left eye and between real and subjectively perceived time.

Eye	Real time (sec)	Subjectively perceived time (sec)	value real vs. perceived
	Mean ± SD	Mean ± SD
Both eyes	261.62 ± 74.79	255.90 ± 131.20	0.686
Right eye	260.76 ± 65.48	258.26 ± 124.98	0.903
Left eye	262.48 ± 83.81	253.54 ± 138.49	0.484
value right vs. left	0.913	0.864
