Purpose: To investigate the possible ocular biometric and keratometric changes in low and high degrees of simple myopia.
Subjects of Methods: A sample of 60 myopic subjects their ages between 10 and 30 years recruited from the Makkah Eye Hospital in Khartoum. In this sample, 30 subjects with myopia < 3.00 D and other 30 subjects with myopia > 6.00 D. Auto keratometry and A-scan biometry were measured from two eyes of each subject.
Results: Subjects with high myopia have longer axial length (AL) (P < 0.0001) compared to low myopic subjects. No significant difference found in front surface corneal power or type of corneal astigmatism between the two groups.
Conclusion: Like previous studies myopia mainly develops with increases in AL of the eye rather than optical changes in cornea or lens. |
