Because of acute retinopathy of prematurity 14 premature infants (900-1,630 g birth weight) were treated with cryocoagulation (10 children, both eyes; 4 only one eye) between 1976 and 1984 and were followed up until they were 2-7 years of age. The average refractive power of 20 eyes (those in which refraction could be determined) was -1.5 +/- 4.1 dptr. Twelve eyes (60.0%) were hyperopic (average: +1.3 +/- 0.4 dptr), and 8 eyes (40.0%) were myopic (average: -5.7 +/- 3.6 dptr). Three eyes in which cryocoagulation was done twice or three times because of a severe course developed pronounced myopia (greater than 7.0 dptr). When comparing both eyes of 4 children in whom cryotherapy had been carried out in only one eye, cryotherapy was found to have no influence on refractive errors (average anisometropia +0.4 +/- 0.4 dptr).
1976年至1984年间，由于早产引起的急性视网膜病变，14名早产婴儿（出生体重900 - 1630克）接受了冷冻凝固治疗（10名儿童双眼治疗；4名仅单眼治疗），并随访至2 - 7岁。20只眼（可测定屈光度的眼）的平均屈光度为-1.5±4.1屈光度。12只眼（60.0%）为远视（平均：+1.3±0.4屈光度），8只眼（40.0%）为近视（平均：-5.7±3.6屈光度）。3只因病情严重接受了两次或三次冷冻凝固治疗的眼出现了明显近视（大于7.0屈光度）。在比较仅单眼接受冷冻治疗的4名儿童的双眼时，发现冷冻治疗对屈光不正无影响（平均屈光参差+0.4±0.4屈光度）。
