Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Medicine - Department of Ophthalmology Summary: This study discusses the IOL power calculation and hence the post operative refractive error through comparison between the use of IOL master and A- scan biometry in measuring the axial length of the eye. This comparison has been done in myopic eyes, silicone filled eyes, and eyes with nuclear cataract grade I&II. This study concluded that The IOL Master has simplified considerably the process of ocular biometry. It is a non-contact technique, which does not require use of topical anesthesia, thus providing comfort to the patient and preventing corneal abrasions and the transmission of infections. Furthermore it has greater accuracy than ultrasound biometry because it measures the ocular AXL along the visual axis, as the patient fixates at the measurement beam, whereas during ultrasound biometry a misalignment between the measured axis and the visual axis may result in erroneously longer AXL measurements. This is especially important in eyes with posterior pole staphyloma because of the more precise localization of the fovea. In addition it is easier to master its use
