Comparison of two different orthokeratology lenses and defocus incorporated soft contact (DISC) lens in controlling myopia progression

Table 3 Percent reduction in AL elongation for the 5.0 mm-BOZD OK, 6.2 mm-BOZD OK and DISC groups versus the SCL group

Parameter	5.0 mm-BOZD OK (%)	6.2 mm-BOZD OK (%)	DISC (%)
Overall	55.81	27.90	46.51
Low myopic groups (SER: − 1.00 D to − 2.50 D)	47.61	11.90	42.86
Moderate myopic groups (SER: − 2.50 D and over)	65.12	44.19	48.84

BOZD = back optic zone diameter; OK = orthokeratology; DISC = defocus incorporated soft contact; SCL = soft contact lens; SER = spherical equivalent refraction
