Mean scores from all 4 graders in all 4 groups (group 1: 32% laser power for − 2.0D treatment), group 2: 64% laser power for − 2.0D treatment, group 3: 32% laser power for − 5.0D treatment and group 4: 64% laser power for − 5.0D treatment). The anterior lenticular surface periphery & centre, anterior cap centre, posterior lenticular periphery & centre and posterior stromal base centre and periphery scans were analysed. (AL-P = anterior lenticule surface periphery; AL-C = anterior lenticule surface centre; CP-C = centre of cap’s posterior surface; PL-P = posterior lenticule surface periphery; PB-P = posterior stroma base periphery; PL-C = posterior lenticule surface centre; PB-C = posterior stroma base centre).

		A : Surface relief (X400) (mean ± standard deviation)	B : Regularity of surface structure (X800) (mean ± standard deviation)	C : Portions of irregular surface (X800) (mean ± standard deviation)	D : Size of the irregular area (X800) (mean ± standard deviation)
