| Abstrakt: | Purpose: To evaluate refraction and its development in young adults born prematurely, screened for retinopathy of prematurity, and to compare with individuals of the same age born at term. Materials and Methods: The participants were 59 preterms, with a birthweight of ≤ 1500 g, and 43 term-born controls, all born during 1988-1990. The refraction was measured in cycloplegia, and the spherical equivalent (SE) was calculated. The axial length (AL), anterior chamber depth and corneal radius (CR) were measured, and the AL/CR ratio was calculated. Results: The mean SE was -0.5 dioptres (D) (SD 2.5) in right eyes (REs) and -0.4 D (SD 2.3) in left eyes (LEs) of preterms, and -0.2 D (SD 1.5) in REs and -0.2 D (SD 1.5) in LEs of controls. The distribution of refraction was wider in the preterm group compared to the control group. In the preterm group, 12% had a SE ≥ 1.5 D, but none of the controls. Ten preterms, but none of the controls, had anisometropia ≥ 1.0 D. The prevalence of astigmatism ≥ 1.0 D was higher in preterms than controls. The SE decreased around 1 D in both preterms and controls from 10 to 25 years of age. The AL and CR were shorter in the preterms; however, the AL/CR ratio was similar in both groups. Within the preterm group, cryotherapy was correlated with astigmatism, but not with SE and anisometropia at this age. Conclusion: Prematurely born individuals had higher prevalence of refractive errors in young adulthood compared to term-born controls. (© 2021 The Authors.
