Amaç: Kırma kusurları ve gözün biyometrik ölçüleri arasındaki ilişkiyi araştırmak.
Materyal ve metod: Bu çalışma oftalmoloji kliniğimizde hasta dosyalarının geçmişe dönük taranmasıyla gerçekleştirildi. Tüm veriler hasta arşivinden elde edildi. Gözün biyometrik ölçümleri 120 fakik bireyin gözü LenStar LS 900 (Haag-Streit AG) cihazı ile ölçülerek elde edildi. Çalışmamıza 40 emetrop, 40 miyop ve 40 hipermetrop birey dahil edildi. Sonuç ölçümleri için tek yönlü ANOVA testi kullanılarak üç grup karşılaştırıldı. Bunlar; Ön kamara derinliği, santral kornea kalınlığı, lens kalınlığı, pupil çapı, aksiyel uzunluk ve retina sinir lifi tabakası kalınlığıdır. Bu çalışmada midriatik ajan damlatılmadı.
Bulgular: Gruplar arası yaş ortalaması emetropik grupta (±SD; 31 ± 5), miyopik grupta (±SD; 33 ± 6), hiper-metropik grupta (±SD; 32 ± 8) olarak bulundu. Gruplar arasında yaş ortalaması açısından anlamlı fark görül-medi (p=0.653). Gruplar arasında ön kamara derinliği (p <0.001), lens kalınlığı (p = 0.016) ve aksiyel uzunluk-ta (p <0.001) anlamlı farklılık vardı. Ön kamara derinliği ve aksiyel uzunluk miyopik grupta anlamlı olarak yüksek bulunurken lens kalınlığı ise hipermetropik grupta anlamlı olarak yüksek bulundu (p< 0.05). Bunun yanı sıra merkez kornea kalınlığı (p = 0.756), göz bebeği çapı (p = 0.462) ve retina kalınlığı (p = 0.646) bakı-mından istatistiksel olarak anlamlı bir fark yoktu.
Sonuç: Bu çalışma gruplar arasında aksiyel uzunluk, ön kamara derinliği ve lens kalınlığı ölçüleri açısından fark olduğunu göstermiştir. Bu anatomik ölçümler arasındaki farkı bilmek bize klinik ve cerrahi çalışmaları-mızda yol gösterici olacaktır.

Background: To evaluate the correlation between refractive error and ocular biometric measures.
Materials and Methods: This study was performed in our ophthalmology clinic by scanning the patients files retrospectively. All data were obtained from the patient archive. Ocular biometric measures were obtained with a LenStar LS 900 optical biometry (Haag-Streit AG) on one eye of 120 phakic subjects. In our study, 40 emmetropes, 40 myopes, and 40 hipermetropes were included. Outcome measures were com-pared for the three groups using One-way ANOVA test. The measures were central anterior chamber depth , central corneal thickness, lens thickness, pupil diameter, axial length and retinal nerve fiber layer thickness. Mydriatic agent was not distilled in our study.
Results: The mean age between the groups was found to be in the emmetropic group (±SD; 31 ± 5), in the myopic group (±SD; 33 ± 6), and in the hyperopic group (±SD; 32 ± 8). There was no significant difference between the groups in terms of mean age (p=0.653). In our study, there were significant differences among groups in anterior chamber depth (p <0.001), lens thickness (p = 0.016), and axial length (p < 0.001). Anteri-or chamber depth and axial length were found to be significantly higher in the myopic group, while lens thickness was significantly higher in the hyperopic group (p< 0.05). However, there were not significant differences among groups for central corneal thickness, (p = 0.756), pupil diameter (p = 0.462), and retinal thickness (p= 0.646).
Conclusions: This study demonstrated the anterior chamber depth, lens thickness, and axial length mea-surements are different among groups. Knowing the difference between these anatomical measurements will guide us in our clinical and surgical studies.
