Preoperative comparison of myopic and hyperopic LASIK groups.

Parameter	Mean ± SD		P Value
Parameter	Myopic (n = 13)	Hyperopic (n = 11)	P Value
MRSE, absolute value (D)	3.4 ± 1.5	2.3 ± 1.3	.09
Cycloplegic refraction SE, absolute value (D)	3.0 ± 1.4	2.6 ± 1.5	.7
Refractive astigmatism (D)	0.4 ± 0.5	0.8 ± 1.2	.35
Age (y)	32 ± 10	52 ± 10	<.001
CCT (μm)	554 ± 32	564 ± 39	.48
Topographic simulated K (D)	44.4 ± 1.1	43.5 ± 1.1	.05

CCT = central corneal thickness, K = keratometry, MRSE = manifest refractive spherical equivalent; SE = spherical equivalent
