Purpose: To elucidate which aspects affect refractive error progression in young adulthood.
Method: Refractive error with Canon RK-F1 and ACD, corneal radius(CR) and axial length(AL) with IOLMaster were measured on 152 eyes of 72 college students with initial age between 18 and 22 years of age in 2008 and 2009 under both manifest and cycloplegic condition.
Result: Myopia increased by an average of -0.080±0.301D(p = 0.000) and was strongly correlated with a -0.015±0.040 mm(p = 0.000) decrease in CR. There was no contribution to the change in myopia from the change in AL. A significant correlation was found between change in SE and CR(r = 0.578, p = 0.000) and in SE and AL/CR ratio(r = -0.542, p = 0.000). But no significant correlation between change in SE and AL(r = -0.074) was found. Myopic group underwent a myopic change of -0.134±0.316D. Myopic progression was significantly greater in the myopic group than in the emmetropic and hyperopic group. Correlations of change in SE and CR(r = 0.664), in SE and AL/CR ratio(r = -0.600) and in CR and AL/CR ratio(r = -0.719) were significant in myopic group. Nothing was significant for emmetropic group. A significant correlation was found between change in SE and CR(r = 0.490) in hyperopic group.
Conclusion: SE, corneal radius and AL/CR ratio changes were significant. It, therefore, is presumed that adulthood myopia is related to not axial length elongation but corneal radius changes caused by accommodation.
