Abstract

Purpose: : To investigate the effect of age on the anterior chamber depth and volume after laser in situ keratomileusis (LASIK) for myopia.

Methods: : One hundred sixty-one eyes of 83 patients (mean age, 34.5±8.3 years) who underwent uneventful LASIK for myopia and myopic astigmatism were included. Subjects were divided into older- (41 years and older) and younger age groups (under 40 years). The corneal thickness, central corneal true net power, the anterior chamber volume (ACV), and the central anterior chamber depth (ACD) were measured using a rotating Scheimpflug camera before and 1 month postoperatively. These parameters were then compared between the two groups.

Results: : The central ACD and the ACV decreased significantly after LASIK in the younger group (P<0.0001, P=0.0050, respectively), although there were no significant differences in the central ACD and ACV in the older group.

Conclusions: : The central ACD and the ACV decreased significantly after LASIK only in younger individuals under 40 years. Age seems to influence the changes in ACD and ACV after LASIK.
