Purpose:
|
To find the most common etiology for anisometropia in pre-op cataract cases:axial or refractive?
|
|
Methods:
|
In this cross-sectional study 41 pre-op cataract paired eyes with more than 0.33 difference between axial lengths of 2 eyes were enrolled.Considered for each 1mm difference between axial lengths in long eyes( AXL more than 25):1.75-2.00 D for anisometropia, for normal eyes(AXL: 22- 25):2.50D and for short eyes (AXL less than 22):3.50-3.75 D as axial anisometropia . If there are more or lesser anisometropia , we recorded as refractive anisometropia.
|
|
Results:
|
Average of anisometropia :4.24 D, prevalence of PK or LK :1(2.38%), kc:1(2.38% ), glaucoma surgery :1( 2.38% ), and pseudophakic status of the opposite eye 8(19.04%). Prevalence of axial anisometropia:21 (52.4%) and refractive anisometropia 20(47.6% ).Then on basis of this study we can rely on the patient’s refraction exactly before phaco for evaluation of axial length differences between the 2 eyes, because most of the anisometropias are axial.
|
|
Conclusion:
|
Pre-cataract refraction is a valuable variable should be measured and recorded in routin eye examination.
