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

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.
