Abstract Details


To review the clinical outcomes of cataract extraction by phacoemulsification with intraocular lens (IOL) implantation, in eyes with acute primary angle-closure (APAC).


Toho University, Omori Hospital


In this retrospective case series, the database of Toho University, Omori Hospital Medical Center was searched for cases of APAC patients with cataract. The following data were collected from the database: age, sex, pre and postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), grading for cataract, complications, additional surgery and requirement for glaucoma drugs.


Forty-two eyes were analyzed. Mean age (+/- SD) was 67.8 +/- 9.8 years (range: 45-88 years). There were 33 female and 9 male patients, with 25 right eyes and 17 left eyes. Mean follow-up duration was 725 +/- 884 days (range: 8-4509 days). In 24 eyes (57%), CDVA improved, in 16 eyes (38%), CDVA remained the same, in 2 eyes (5%), CDVA deteriorated after surgery. IOP was decreased from a mean preoperative level of 46.1 +/- 20.1 mmHg (range: 5-62 mmHg) to 12.6 +/- 3.7 mmHg (range: 4-21 mm Hg) at final follow-up. Mean preoperative grading for cataract was 2.2 (Emery-Little classification). The perioperative complications were posterior capsule rupture and zonular dehiscence in 4 eyes (9.6%). The postoperative complication was IOP peaks in 5 eyes (12%). Goniosynechiolysis (GSL) was performed in 15 eyes (35.7%) at primary cataract extraction. Trabeculectomy was performed in 2 eyes (4.8%) postoperatively. The number of glaucoma eye drops required was 0.67 +/- 1.1 (range: 0-3) at final follow-up. The IOP at final follow-up and the number of glaucoma eye drops for the GSL group was higher, also was more than those for the non-GSL group respectively (p<0.01).


In APAC patients with cataract, cataract extraction by phacoemulsification can improve preoperative CDVA and IOP. Indication for GSL will be needed further investigation. FINANCIAL DISCLOSURE?: No
