TABLE 3.

Maximum Residual Stromal Bed Displacements for Flap-Based (FLEx) and Flapless (SMILE) Refractive Surgery in Contralateral Eye Models as a Function of IOP Measured From the No-Load State to the Specified IOP Load^a

Variable	SMILE at 15 mm Hg	SMILE at 30 mm Hg	FLEx at 15 mm Hg	FLEx at 30 mm Hg
Patient 1	701	1,140	729	1,190
Patient 2	813	1,267	800	1,261
Patient 3	690	1,120	705	1,150
Patient 4	669	1,040	690	1,080
Patient 5	833	1,313	863	1,353
Mean ± SD	741 ± 76	1,176 ± 112 (+58.7%)	757 ± 73	1,207 ± 105 (+59.5%)
P (difference between SMILE and FLEx)			.10	.03

SMILE = small incision lenticule extraction; FLEx = femtosecond lenticule extraction; IOP = intraocular pressure

Measured in microns.
