Abstract
Objectives: To evaluate the effect of phacoemulsification on intraocular pressure (IOP) at one week after surgery among glaucoma patients with cataracts. A further aim was to investigate whether there was a correlation between axial length (AL), anterior chamber depth (ACD) and K-readings with pre- and postoperative IOP.
Methods: A retrospective analysis was performed on 212 eyes of 212 glaucoma patients with cataracts who had undergone uncomplicated phacoemulsification and foldable intraocular lens implantation. The measurements were obtained preoperatively and 1 week postoperatively. AL, ACD, and K-reading were measured by Zeiss IOL Master Version 5, and IOP was measured by Noncontact tonometer Nidex NT-530P. The relationships between IOP change and ocular biometric parameters were evaluated.
Results: The mean age of the patients was 70.7 ± 8.6 years; 72 patients were male, and 140 patients were female. The difference between pre- and postoperative IOP was 2.95 ± 2.52 mmHg. The mean AL, ACD, and K-reading were 23.4 ± 1.1 mm, 2.98 ± 1.89 mm, 44.2 ± 3.9 Diopter, respectively. There was a significant correlation (p <0.05) between the difference of preand postoperative IOP >3 mmHg, and AL and preoperative IOP, whereas there was no significant correlation with ACD and K-reading.
Conclusion: Phacoemulsification induces a reduction in IOP in glaucoma patients with cataracts. Preoperative IOP > 15mmHg, AL > 23.42mm and ACD ≤ 2.72 mm were also significantly associated positively with reduced IOP after cataract surgery.
