Abstract

Purpose: To investigate the relationship between refractive error and ocular biometry in healthy subjects using a new optical low coherence reflectometry device. Methods: Biometric measurements were obtained with a LenStar LS 900 (Haag Streit, Switzerland) on one eye of 70 phakic subjects (mean ± SD age; 29 ± 9 years). Forty myopes and 30 non-myopes (best sphere range -9.63. D to +0.63. D) were included. Outcome measures were compared for the two groups using one way between groups ANOVA. These included; keratometry, central corneal thickness, iris width, anterior chamber depth, pupil diameter, lens thickness, axial length and retinal thickness. No mydriatic or cycloplegic agents were used. Results: There were significant differences between groups for keratometry readings (p=0.021 and p=0.038 for steep and flat k readings respectively), anterior chamber depth (p=0.001), lens thickness (p=0.026) and axial length (p
