Abstract

Amaç: Bu çalışmanın amacı oftalmolojik muayenede sikloplejik-midriyatik olarak kullanılan %1 siklopentolat hidroklorür damlanın korneal keratometrik değerlere etkisini araştırmak, siklopleji-midriazis sonrası ölçülen keratometrik değerlerin refraktif cerrahi ve biyometrik hesaplamalarda kullanılıp kullanılamayacağını ortaya koymaktır.

Yöntemler: Kesitsel prospektif planlanan çalışmaya, Ocak 2022-Nisan 2023 tarihleri arasında rutin göz muayenesi için polikliniğe başvuran sağlıklı erişkin 110 hastanın sağ gözü dâhil edildi. Standart otorefraktokeratometreyle (Topcon KR 8100) ölçülen korneal keratometrik veriler (K1, K1mm, K1 aks, K2, K2mm, K2 aks, K ortalama, korneal astigmatik değer) %1 siklopentolat hidroklorür 3 defa damlatıldıktan 45 dakika sonra elde edilen siklopleji sonrasındaki keratometrik ölçümlerle karşılaştırıldı.

Bulgular: Olguların medyan yaşı 25 (minimum 18-maksimum 40 yıl) idi. Cinsiyet dağılımı eşitti. Olguların siklopleji öncesi ölçülen K1, K1mm, K1 aks, K2, K2mm, K2 aks, K ortalama, korneal astigmatik değerlerinde siklopleji-midriyazis sonrasında istatiksel olarak anlamlı fark saptanmadı (p>0,05).

Sonuç: Sağlıklı erişkin bireylerde korneal keratometrik değerler %1 siklopentolat ile oluşturulan siklopleji-midriyazisten etkilenmemektedir.

Effect of cycloplegia on corneal keratometric measurements in myopic patients

Abstract

Aim: The purpose of this study was to investigate the effect of 1% cyclopentolate hydrochloride drops used as cycloplegic-mydriatic in ophthalmologic examination on corneal keratometric values and to determine whether keratometric values measured after cycloplegia-mydriasis can be used in refractive surgery and biometric calculations.

Methods: The cross-sectional prospective study included the right eye of 110 healthy adult patients who presented to the outpatient clinic for routine ophthalmologic examination between January 2022 and April 2023. Corneal keratometric data (K1, K1mm, K1 axis, K2, K2mm, K2 axis, K mean, corneal astigmatic value) measured with a standard autorefractokeratometer (Topcon KR 8100) were compared with keratometric measurements after cycloplegia obtained 45 minutes after 3 instillations of 1% cyclopentolate hydrochloride.

Results: The median age of the patients was 25 years (minimum 18-maximum 40 years). Gender distribution was equal. There were no statistically significant differences in corneal keratometric values (K1, K1mm, K1 axis, K2, K2mm, K2 axis, K mean, corneal astigmatic value) before and after induction of cycloplegia (p>0.05).

Conclusion: Corneal keratometric values are not affected by cycloplegia-mydriasis induced by 1% cyclopentolate in healthy adult subjects.
