Abstract
Objective: To assess the effect of pupillary dilatation on ocular biometric measurements (AL, ACD, flattest and steepest corneal curvatures ”K1 and K2” respectively) and IOL power calculation by using IOLmaster device.
Study design: A Cross sectional study.
Study setting: This study was conducted at the outpatient clinic, Department of Ophthalmology, Kobry ElQuobba Military Medical compound, Cairo. from October 2015 to May 2016.
Patients: Ninty nine eyes from 62 patients with an age of more than 40 years and had senile cataract who came for eye examination and cataract surgery were included in this study.
Result: There were no statistically significant differences between the AL and K reading (Flattest K and Steepest K), and IOL power. However, the ACD and WTW were significantly increased post-dilatation (P value > 0.001).
Conclusion: Pupillary dilatation does not affect the measurement of the AL, K readings and the IOL power, with the exception of ACD and WTW. It means that we can do ocular biometry measurement for IOL calculation within the same day, after we have dilated the patient’s eye and examined it thoroughly. Thus, patients need not come back for another visit, which is a practical benefit to them.
