ÖZET
 Amaç: Bu çalışmada, yeni bir biyometri yöntemi olarak kullanıma giren, optik koherens tomografi biyometrisi (B-OKT) olan Revo NX tarafından yapılan optik biyometrik ölçümleri, 2 onaylı biyometri cihazı olan IOLMaster 700 ve Lenstar LS-900 ile karşılaştırmayı amaçladık. Gereç ve Yöntemler: Bu retrospektif çalışmada, 80 yaş altındaki olguların kayıtları tarandı ve optik biyometrik ölçümleri arasında korelasyon analizi yapıldı. B-OKT olan Revo NX, IOLMaster 700, Lenstar kullanılarak ölçülmüş olan; aksiyel uzunluk [axial length (AL)], ön kamara derinliği (ÖKD), lens kalınlığı (LK) ve santral kornea kalınlığı (SKK) değerleri arasındaki uyum karşılaştırıldı. Ölçümlerin benzerliği, sınıf içi korelasyon katsayıları [inter class correlation (ICC)] değerlendirilerek kıyaslandı. Her üç cihazla da ölçüm hatası oranları kaydedildi ve karşılaştırıldı. Bulgular: Çalışmaya yaşları 14-77 arasında olan 33 kadın ve 28 erkek olmak üzere toplam 61 olgu alınmıştır. Revo NX, Lenstar ve IOLMaster grupları arasında AL, ÖKD, LK ve SKK değerleri karşılaştırıldı ve gruplar arasında anlamlı fark bulunmadı. Revo NX-Lenstar-IOLMaster arasında AL, ÖKD ve LK değerlerinin uyumuna bakıldığında, yüksek derecede uyum olduğu görüldü (ICC değeri AL için 1, ÖKD için 0,997, LK için 0,990). Sonuç: Sonuç olarak Revo NX, arka segment için optimize edilmiş, oküler eksenel boyutların doğru ölçümlerini, ön segment yapılarının görüntülenmesini sağlayan ve retinayı değerlendirmek için ek bir cihaz gerektirmeyen multimodal bir görüntüleme platformu olarak kabul edilebilir. Arka ve ön segment görüntüleme için piyasada bulunan OKT cihazlarında önerilen B-OKT yönteminin uygulanması, oküler aksiyel boyutların rutin olarak ölçülmesini sağlayarak, işlevlerini genişletecektir.

ABSTRACT
 Objective: In this study, we aimed to compare the optical biometric measurements made by Revo NX, an optical coherence tomography biometry (B-OCT), which has come into use as a new biometrics method, with the 2 approved biometrics devices IOLMaster 700 and Lenstar LS-900. Material and Methods: In this retrospective study, records of patients under 80 years of age were scanned and correlation analysis was performed between optical biometric measurements. Revo NX with B-OCT, IOLMaster 700, measured using Lenstar; The agreement between axial length (AL), anterior chamber depth (ACD), lens thickness (LT) and central corneal thickness (CCT) values were compared. The similarity of the measurements was compared by evaluating the within-class correlation coefficients (ICC). Measurement error rates were recorded and compared with all three devices. Results: A total of 61 patients, 33 female and 28 male, aged between 14-77 years, were included in the study. AL, ACD, LT and CCT values were compared between the Revo NX, Lenstar and IOLMaster groups, and no significant difference was found between the groups. Considering the compatibility of AL, ACD and LT values between Revo NX-Lenstar-IOLMaster, it was seen that there was a high degree of agreement (ICC value was 1 for AL, 0.997 for ACD, 0.990 for LT). Conclusion: In conclusion, Revo NX can be considered as a multimodal imaging platform that is optimized for the posterior segment, provides accurate measurements of ocular axial dimensions, visualization of anterior segment structures, and does not require an additional device to evaluate the retina. Implementation of the proposed B-OCT method in commercially available OCT devices for posterior and anterior segment imaging will expand their functionality by enabling routine measurement of ocular axial dimensions.
