Objective To evaluate the efficacy and safety of prompt phacoemulsification, intraocular lens implantation, visco-goniosynechialysis, combined with pseudo-pupilloplasty for refractory acute primary angle closure (APAC) with atonic dilated pupil and to describe a feasible method of pupilloplasty. Methods A consecutive series of refractory APAC patients who had atonic dilated pupil and undergone prompt phacoemulsification combined with pseudo-pupilloplasty at our center were retrospectively analyzed. Pseudo-pupilloplasty referred to a method of pupilloplasty which included 4.5-mm capsulorhexis, postoperative opacification of anterior capsule residue, and ultimate pseudo-pupil formation. Preoperative and postoperative measurements included intraocular pressure (IOP), best corrected visual acuity (BCVA), and anterior chamber depth (ACD). Intraoperative and postoperative complications were documented. The process of pseudo-pupil formation was also observed. Results A total of 20 eyes of 19 APAC patients were followed up for 19.7 ± 9.8 months. IOP was lowered from preoperative 44.0 ± 9.8 mmHg to 15.5 ± 2.6 mmHg at final visit (t=11.945, P < 0.001). ACD was deepened from preoperative 1.77 ± 0.21 mm to 3.40 ± 0.20 mm at final visit (t=-27.711, P < 0.001). Twelve of 20 eyes had residual angle synechiae, whereas only 3 eyes needed anti-glaucoma medications. No severe complication was observed. All eyes had pseudo-pupil gradually formed within 3 months, accompanied with the gradual improvement of BCVA from preoperative 1.18 ± 0.55 to 0.58 ± 0.22, 0.26 ± 0.09, 0.11 ± 0.09, and 0.11 ± 0.09 at postoperative day 1, month 1, month 3, and last visit. Conclusions Prompt phacoemulsification-goniosynechialysis is effective and safe for refractory APAC with atonic dilated pupil. Pseudo-pupilloplasty is a feasible procedure for pupil reconstruction.
