BACKGROUND A new commercially available device (IOLMaster, Zeiss Instruments) provides high resolution non-contact measurements of axial length (using partial coherent interferometry), anterior chamber depth, and corneal radius (using image analysis). The study evaluates the validity and repeatability of these measurements and compares the findings with those obtained from instrumentation curre...

Purpose: To establish the importance of ocular biometry in congenital and infantile cataract upon the visual outcomes. Methods: The study was a retrospective study upon patients with congenital and infantile cataract. The study group included 58 eyes from 36 children. For cooperative children, for the ocular biometry we used the OCUSCAN biometer (Alcon, Forth Worth Tx). In very young children w...

PURPOSE To investigate normative angle kappa data and to examine whether correlations exist between angle kappa and ocular biometric measurements (e.g., refractive error, axial length) and demographic features in Koreans. METHODS Data from 436 eyes (213 males and 223 females) were analyzed in this study. The angle kappa was measured using Orbscan II. We used ocular biometric measurements, inc...

BACKGROUND To evaluate the relationship between age, axial length (AL), anterior chamber depth (ACD) and corneal steepness (K) in patients with cataract. METHODS In this retrospective study, medical records of 800 patients (800 eyes) who were diagnosed with cataract and received preoperative ophthalmologic examination were reviewed. Data including age, gender and ocular biometric data includi...

PURPOSE To investigate the association between ocular biometrics such as axial length (AL), anterior chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD) and corneal power (CP) with different refractive errors. METHODS In a cross-sectional study on the 40 to 64-year-old population of Shahroud, random cluster sampling was performed. Ocular biometrics were measured using the A...

Axial length of the eye correlates with magnitude myopia. However, there are conflicting reports on relationship between certain corneal parameters myopia magnitude. The objective this study was to compare ocular biometry and emmetropic myopic groups. Participants (n=127) were categorized as emmetropia (spherical equivalent, SE, ±0.50D), low (-0.75D≤SE<-6.00D) high (SE≥-6.00D). difference in...
