AIM: To study the clinical efficacy of phacoemulsification and intraocular lens implantation for cataract patients with different angle-closure degree of angle-closure glaucoma.

METHODS: There were 31 patients 35 eyes who were with angle-closure glaucoma and cataract. According to the degree of angle closure adhesions, they were divided into groups A, B. Group A(the angle closure adhesions ≤ 90 °)had 19 eyes, group B(the angle closure adhesions 90° -180°)had 16 eyes. Phacoemulsification and intraocular lens implantation were performed for both groups. The preoperative and postoperative visual acuity, intraocular pressure(IOP), anterior chamber depth, angle changes and the length of the axial length, lens thickness, vitreous length in the two groups were observed and statistically analyzed.

RESULTS: The angle-closure glaucoma with cataract patients' visual acuity was improved and the angle deepened. Gonioscopy: The number of fully open angle was 16 in the group A(84%). And in the group B, completely open angle was 13 eyes(81%). The difference of A and B was not statistically significant(P>0.05). IOP: preoperative IOP was 35.13± 4.18mmHg in A, and in B was 45.01±5.31mmHg. After 1 week, IOP in group A was controlled in 14.25 ± 3.22mmHg and group B was 14.30±3.19mmHg, there was no statistical significance(P>0.05).

CONCLUSION: Positive relationship exists between the proportion of axial length, lens thickness and vitreous length. For angle-closure glaucoma with cataract patients, a simple surgery of the phacoemulsification can effectively treat angle-closure adhesions ≤ 180 °, and for patients with angle-closure adhesions> 180 °, the joint treatment of glaucoma surgery can be considered.
