Abstract Cataract is the progressive loss of lens transparency. Despite being treatable, cataract is the most common ocular disease and a leading cause of vision loss. Accurate biometry is of great importance for the calculation of the precise refractive power of the intraocular lens (IOL) power calculation in cataract surgery. Some certain types of cataracts may have a potential to create difficulties when performing optical biometry. Dilating the pupil can serve to aid in obtaining biometrical parameters when the surgeon face such a problem. Does dilating the pupil may affect the parameters? This particular question is what we are trying to answer through this study. Thirty eyes of cataract patients were included in our study (15 left eyes and 15 right eyes). The mean age of the study population was 57.57±8.61. 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 candidates were subjected to full ophthalmological examination including VA, slit lamb biomicroscopy, BCVA, applanation tonometry, fundus examination and IOL power measurement using IOL Summary (70) master 700 before and after pupillary dilatation using 1 % tropicamide eye drops. This study revealed that biometric measurements as AL, K1 and K2 were not affected by pupillary dilatation. While ACD was significantly affected with p value 0=024. Although ACD was affected it did not affect IOL power. Which means that IOL power measured with dilatation is reliable and it can be used to decide IOL used in cataract surgery. |
