Purpose:
|
To evaluate validity of simplified Javal’s rule (Total Ast=Corneal Ast- 0.50@90)in 147 pre-op cataract eyes.
|
|
Methods:
|
Due to change in lens tissue and structure in a cataract crystalline lens, we conceive the simplified javal’s rule may not be valid in cataract cases.In this cross-sectional study,147 pre-op cataract eyes without oblique astigmatism were enrolled in this study.Ocular biometry(with IOL master 500)and keratometry and refraction findings were recorded.
|
|
Results:
|
Mean age of our patients was 64.95 ±9.86yrs/old, that confirms on senile cataract. Mean Axial length and average keratometry were respectively 23.86 and 44.62. Prevalence of systemic diseases diabet and high blood pressure were respectively 43(29.25%) and 44( 29.93% )and shows importance of these diseases. The Corneal astigmatism axis is correlated with refractive astigmatism in cataract eyes(r= 0.493).Simplified Javal’s rule is valid in cataract eyes (P<0.001).
|
|
Conclusion:
|
Simplified Javal’s rule is a valid formula in pre-op cataract eyes and can be used for keratometry results confirmation.
