Abstract

Aim:
Investigation of the efffects of using topical anesthetic on axial length (AL),
average keratometry (AK), central corneal thickness (CCT), anterior chamber
depth (ACD), intraocular lens power (IOLP).

Patient and methods: 15 female and 15 male emetrop patients , applied to our our polyclinic
for routine eye examination, who don’t have any ocular or systemic disease,
don’t use medication related to ocular or systemic diseases. The cases were
between between 18-26 years old and avarage age was
  22,80±2,29 years. 30 eyes of those 15
people were examined. The right eyes were taken as the study group while left
eyes were taken as the
  control group.
Study group (right eyes) was separated in to 3 groups with regard to time
intervals of measurements as; before topical anesthetic (0.5 % proparacaine
hydrochloride, Alcaine, Alcon), after 20 seconds and after 2 minutes. No
anesthetic were applied to control group (left eyes) although all the
measurements were made at the same time intervals. All measurements were made
with optical biometry device (ALScan, Nidek, Japan). 

Results:
There was no change in all the measurements of
 
the control group's  before drop,
after 20 sec and after 2 mins (p>0.05) intervals. There wasn’t any
significant difference in both study group's and control group's AL, AK, ACD
and IOLP measurements between their own time intervals(p>0.05). However CCT
measurements of after 20 sec were significantly higher than both before drop
and after 2 minutes' intervals, as well as compared to control group's
measurements (p<0.05). Although no significant difference was observed
between before drop, after 2 mins and control group (p>0.05).


























Conclusion:
In this study, we observed that anesthetic drop doesn’t have an effect on AL,
AK, ACD and IOLP measurements. However we suggest taking CCT measurement which
is made 20 sec after the drop into consideration just because it was
significantly different from other groups, especially when examining the
intraocular pressure.

Topikal Anestezik Damlanın Oküler Biyometri Ölçümlerine Etkisinin İncelenmesi

Abstract

Amaç:
Topikal anestezik kullanımının aksiyel uzunluk(AU), ortalama keratometri(KM),
merkezi kornea kalınlığı (MKK), ön kamara derinliği (ÖKD), göz içi lens güç
(GİLG) değerlerine etkisinin incelenmesi.

Hastalar ve Yöntem: Çalışmaya rutin göz muayenesi için polikliniğimize başvuran herhangi
bir oküler veya sistemik hastalığı olmayan, sistemik veya oküler ilaç
kullanmayan emetrop kişiler dahil edildi. Olguların ortalama yaşı 22,80±2,29 (18-26)
yıldı. 15 erkek 15 kadın, 30 kişinin 30 gözü çalışmaya dahil edildi, sağ gözler
çalışma, sol gözler kontrol grubu olarak kabul edildi. Çalışma grubu kendi
içinde topikal anestezik (% 0.5 proparakain hidroklorür,Alcaine,Alcon)
  öncesi, 20 saniye sonrası  ve 2 dakika sonrası değerleri olarak üçe
ayrıldı. Diğer gözlere topikal anestezik damlatılmadı ve başlangıç, 20 saniye
ve 2 dakika sonrası değerler alındı. Tüm ölçümler optik biyometri (ALScan Nidek
Japonya) cihazı ile yapıldı. 

Bulgular:
Kontrol grubunda başlangıç, 20 saniye sonrası ve 2 dakika sonrası tüm ölçüm
değerlerinde herhangi değişiklik izlenmedi.(p>0.05)
  Çalışma grubunda AU,ÖKD,KM ve GİLG
değerlerinde hem çalışma grubunun başlangıç, 20 saniye ve 2 dakika sonrası
değerleri arasında hem de kontrol grubunun değerleri arasında anlamlı farklılık
izlenmedi. (p>0.05)
  MKKde ise
anestezik damladan 20 saniye sonrası değerler hem damla öncesi, hem 2 dakika sonrası
ve hem de kontrol grubundan istatistiksel olarak anlamlı farklı bulundu.
(p<0.05)


























Sonuç:
Çalışmamızda AU, KM, ÖKD ve GİLG hesaplamalarına anestezik damlatılmasının
etkisinin olmadığını gözlemledik. MKK de ise damladan 20 saniye sonrası
değerlerin anlamlı derecede yüksek bulunmasından dolayı bunun özellikle göz içi
basıncı ölçümünde göz önünde bulundurulmasını önermekteyiz.
