Abstract
Objective: To evaluate the changes in anterior chamber depth (ACD) and angle width induced by phacoemulsification and intraocular lens (IOL) implantation in cataract eyes using high frequency ultrasound biomicroscopy (UBM).
Subjects and methods: A prospective clinical intervention study of thirty-one eyes of 31 cataract patients underwent phaco surgery with IOL implantation at Hue Central Hospital from March to May 2017. Using UBM imaging we analyzed the central ACD and angle width by different methods: anterior chamber angle (ACA), trabecular-iris angle (TIA), angle opening distance (AOD), and trabecular iris surface area (TISA). Comparison between preoperative and postoperative measurement was done at 1 week, 1 month and 3 months after surgery.
Results: 31 patients including 13 males (42%), 18 females (58%). Average age: 69.58 ± 11.9. Changes in IOP before and after surgery at 1 week, 1 month, 3 months were 19.16 ± 4.52 mmHg; 14.55 ± 2.79mmHg; 14.16 ± 2.10mmHg; 13.61 ± 1.91mmHg. The change of ACA on UBM before and after surgery at 1 month, 3 months was as follows: ARA: 0.0985 ± 0.010mm2 ; 0.163 ± 0.007mm2 ; 0.166 ± 0.008mm2 ; AOD250:
162.45 ± 21.53μm; 352.50 ± 21.53μm; 361.71 ± 23.95μm; AOD500: 266.00 ± 24.59μm; 570.32 ± 14.43μm;
578.56 ± 19.44μm; TIA: 14.63 ± 3.87°; 28.30 ± 4.19°; 31.13 ± 3.58°; 2.23 ± 0.26mm; 3.21 ± 0.15mm; 3.20 ±
0.23mm. ARA, AOD, and TIA increased significantly after cataract surgery and showed positive correlation with ACD (p<0.05)
Conclusions: After phaco surgery, the ACD and angle width significantly increased in eyes with cataract. UBM is a good method for obtaining quantitative data regarding anterior chamber configuration.
