PURPOSE: To investigate, by high-precision digital analysis of data provided by Scheimpflug imaging, changes in pupil size and shape and anterior chamber (AC) parameters following @entity231 surgery. @entity1 AND METHODS: The study group (86 eyes, @entity1 age 70.58  10.33 years) was subjected to @entity231 removal surgery with in-the-bag intraocular lens implantation (pseudophakic). A control group of 75 healthy eyes ( @entity1 age 51.14  16.27 years) was employed for comparison. Scheimpflug imaging (preoperatively and 3 months postoperatively) was employed to investigate central corneal thickness, @entity8707 , and AC volume. In addition, by digitally analyzing the black-and-white dotted line pupil edge marking in the Scheimpflug "large maps," the horizontal and vertical pupil diameters were individually measured and the pupil eccentricity was calculated. The correlations between @entity8707 and pupil shape parameters versus @entity1 age, as well as the postoperative AC and pupil size and shape changes, were investigated. RESULTS: Compared to preoperative measurements, @entity8707 and AC volume of the @entity735 increased by 0.99  0.46 mm (39%; P<0.001) and 43.57  24.59 mm(3) (36%; P<0.001), respectively. Pupil size analysis showed that the horizontal pupil diameter was reduced by -0.27  0.22 mm (-9.7%; P=0.001) and the vertical pupil diameter was reduced by -0.32  0.24 mm (-11%; P<0.001). Pupil eccentricity was reduced by -39.56%; P<0.001. CONCLUSION: Cataract extraction surgery appears to affect pupil size and shape, possibly in correlation to @entity8707 increase. This novel investigation based on digital analysis of Scheimpflug imaging data suggests that the @entity231 postoperative photopic pupil is reduced and more circular. These changes appear to be more significant with increasing @entity1 age.
