THE EFFECT OF RELIGIOUS FASTING ON WAVEFRONT ABERROMETER PARAMETERS Oruç Tutmanın Wavefront Aberometre Değerlerine Etkisi
Abstract
Objective: Increased tear osmolarity and ocular surface inflammation during Ramadan fasting have been
associated with alterations in anterior segment parameters. The primary aim of this study was to investigate
the effect of religious fasting on refractive measures.
Material and Methods: Spherical equivalent, keratometry (K1, K2), and wavefront of all order aberrations
and high order aberrations were scanned by iDesign Advanced WaveScan Studio (Abbott®, USA). Effective
blur, high order percentages, polar Zernike coefficients at 6 mm and root mean square errors were also
analysed. Thinnest pachymetry, corneal volume and anterior chamber volume were evaluated by Pentacam
HR (Oculus®, Germany). The IOLMaster 500 (Zeiss®, Germany) was used to measure the axial length. Only
the measurements of right eyes were used for statistical analysis. All measurements were performed at 4
pm one week prior to Ramadan (non-fasting period) and during last week of Ramadan (fasting period, 1
month later).
Results: Thirty-two eyes of 32 healthy volunteers (21 male and 11 female) were analysed. The mean age
was 35.44±7.5 (18-49) years. No significant differences were found between fasting and non-fasting periods
both in iDesign aberrometer corneal topography and biometry devices (p>0.05).
Conclusion: The refractive measures seem not to be altered during religious fasting period. There is no need
to postpone the preoperatory refractive measures in refractive surgery candidates during religious fasting.

ÖZET
Amaç: Ramazan ayında oruç tutmaya bağlı gözyaşı ozmolaritesinde ve oküler yüzey iltihabında artış olması
ön segment parametrelerinde değişikliklere neden olabilmektedir. Bu çalışmanın ana amacı oruç tutmanın
refraktif ölçümlere etkisinin incelenmesidir.
Gereç ve Yöntemler: Sferik eşdeğer, keratometri değerleri (K1, K2), tüm sıralı aberasyonlar ve yüksek sıralı
aberasyonlar iDesign Advanced WaveScan Studio (Abbott®, ABD) cihazı ile tarandı. Efektif bulanıklık, yüksek
sıra yüzdeleri, 6mmlik alandaki polar Zernike katsayıları ve kare kök ortalama hataları analiz edildi. En ince
kornea kalınlığı, kornea hacmi, ön kamara hacmi Pentacam HR (Oculus®, Almanya) ile değerlendirildi. Aksiyel
uzunluk ise IOLMaster 500 (Zeiss®, Almanya) ile ölçüldü. İstatistik analiz için sadece sağ gözden alınan
ölçümler kullanıldı. Tüm ölçümler saat 16:00’da ramazan ayından 1 hafta önce oruçsuz dönemde ve ramazan
ayının son haftasında (1 ay sonra) oruçlu iken yapıldı.
Bulgular: Toplam 32 sağlıklı gönüllünün (21 erkek ve 11 kadın) 32 gözü incelendi. Ortalama yaş 35,44±7,5
(18-49) yıl idi. Ramazan öncesi ve ramazan ölçümleri arasında incelenen tüm ölçümlerde istatistiksel olarak
anlamlı fark saptanmadı (p>0,05).
Sonuç: Oruçlu olunan dönemde refraktif ölçümler değişmiyor olarak gözükmektedir. Refraktif cerrahi adaylarında
oruçlu oldukları dönemde cerrahi hazırlığının refraktif sonuçlar açısından ertelenmesine gerek yoktur.
