| CR at 6 years (mean (SD)) | Group M-0 (36 eyes) | Group M-1 (57 eyes) | Group M-2 (32 eyes) | Total (29 eyes) | |
| Cryotherapy (−) | −6.18 (3.91) | 0 (00.0) | 7 (58.3) | 5 (41.7) | 12 (100) |
| Cryotherapy (+) | −2.79 (4.46) | 5 (29.4) | 7 (41.2) | 5 (29.4) | 17 (100) |
↵p Value = 0.045 (t test).
CR=cycloplegic refraction.
Group M-0=emmetropia or hyperopia; group M-1=myopia (<−6.0 D); group M-2=high myopia (⩾-6.0 D).
