Abstract
SUMMARY
The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient.
This study is to evaluate The Effect of Pupillary Dilatation on Intra-Ocular Lens (IOL) Power Measurements by Using the IOL master.
Fifty eyes of cataract patients were included in our study (23 left eyes and 27 right eyes). The mean age of the study population was 51.08 ± 9.91 (range, of 30-85 years).
Patients with past history of ocular trauma, ocular surgeries, corneal opacities, Ocular pathology like glaucoma, uveitis, retinal disease or any systemic disease were excluded from this study.
Our study revealed that dilatation does not affect the SRK/T calculated IOL power and we found that AL and keratometric biometry (K1, K2) were not affected by dilatation; however, the ACD was significantly increased post-dilatation (with mean difference -0.1 ±0.03mm; P-value < 0.05.
