Comparison of rates of myopic progression among four kinds of OK lenses over a 1.5-year period of use.
| No progression | Slow progression | Fast progression | |
|---|---|---|---|
| ER: ≤ 0.00 D | ER: 0.00–1.00 D | ER ≥ 1.00 D | |
| AL: ≤ 0.15 mm | AL: 0.15–0.4 mm | AL > 0.4 mm | |

| CRT | 26.7% | 36.0%*,† | 37.3%*,†,‡ |
| Euclid | 22.1% | 56.6%* | 21.3%* |
| Alpha | 26.3% | 53.5%† | 20.2%† |
| Hiline | 32.2% | 37.0% | 30.8%‡ |

Corrected pairwise comparison of P-values are represented by
*
, significant (P < 0.05) difference between CRT and Euclid.
†
Significant difference between CRT and Alpha.
‡
Significant difference between CRT and Hiline. Pairwise comparison is corrected for multiple comparisons. ER, estimated refraction. No progression means reduction (or no change) in refraction or less than (equal to) 0.15 mm AL elongation. Slow progression means 0 to 1 D refraction growth or 0.15 to 0.4 mm AL elongation. Fast progression means more than 1 D refraction growth or more than 0.4 mm AL elongation.
