Abstract Details


To investigate the effect of phacoemulsification and intraocular lens implantation on anterior chamber parameters


Department of Ophthalmology Istanbul Faculty of Medicine Istanbul Turkey


Eighty-nine eyes of 75 patients who underwent uneventful phacoemulsification and intraocular lens implantation from July 2015 to January 2016 were prospectively evaluated. Goldman applanantion tonometer was used to measure intraocular pressures (IOP), and Pentacam dual Scheimpflug camera to measure anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) and central corneal thickness (CCT) preoperatively and at 1 week, 1 month and 3 months postoperatively. These changes were compared regarding age, gender, cataract grade and axial length.


Mean age was 65 years. Mean axial length was 23.41mm and mean IOP was 14.88 mmHg preop and decreased to 13.75 postop. Median ACD was 2.45 mm preop and increased to 4.05mm, 4.11mm and 4.18mm at 1 week, 1 month and 3 weeks postop, respectively. Median ACA was 28.0 preop and increased to 40.3, 41.0 and 41.7 degrees postoperatively. Median ACV was 122 preop and increased to 172, 176 and 180mm3 postop. Differences between ACD, ACV, ACA and IOP values taken preoperatively and those taken postoperatively were statistically significant.


Uneventful phacoemulsification significantly reduced IOP, increased ACD and ACV and widened ACA. However, these changes were not significant regarding age, gender and cataract grade. These changes remained almost stable after the first month of surgery.
