Abstract

To evaluate the changes in anterior segment morphometry and intraocular pressure (IOP) with 3D rotating Scheimpflug camera-topography system after uneventful phacoemulsification. Materials and methods: In 56 eyes of 54 patients, anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), and central corneal thickness (CCT) were measured with the Sirius 3D Rotating Scheimpflug camera-topography system preoperatively and 1 month after surgery. IOP was measured with applanation tonometer. The preoperative and postoperative results were compared. Results: Preoperative and postoperative anterior segment parameters were as follows: ACD 2.7 ± 0.4 and 3.5 ± 0.3 mm, ACV 143.6 ± 48.8 and 192.4 ± 59.5 mm3, nasal ACA 42.3 ± 8.4° and 53.0 ± 4.5°, temporal ACA 36.9 ± 11.9° and 45.8 ± 13.2° (P < 0.001). CCT, iris diameter, and pupil diameter changes were not statistically significant (P > 0.05). Mean axial length (AL) was 23.4 ± 0.8 mm. The IOP and corrected IOP were 14.6 ± 3.5 and 14.5 ± 3.9 preoperatively and 10.4 ± 2.4 and 10.0 ± 3.3 mmHg postoperatively (P < 0.001). There was not a correlation between AL and IOP, ACD, ACV, or ACA, and no correlation was found between IOP change and ACD, ACV, or ACA (P > 0.05). Conclusion: Measurements confirm that after uneventful phacoemulsification, IOP decreases while ACD, ACV, and ACA increase. Preoperative AL and IOP changes did not correlate with ACD, ACV, and ACA.
