Clinical Analysis of Glaucoma Triple Procedure of Extracapsular Cataract Extraction and Posterior Chamber Intraocular Lens Implantation Combined with Trabeculectomy

ABSTRACT

Glaucoma triple procedure of extracapsular cataract extraction and posterior chamber intraocular lens implantation combined with trabeculectomy which was undergone in 21 eyes(20 cases) since May 1984, were reviewed. The results as follows. 1. In the distribution of sex and age of 20 patients, 16 patients(75%) were male, and seventies, which were most common, were 9 patients(45.0%); fifties, 5; forties, 1; thirties, 1. The average age was 63.9 years old. 2. In type of glaucoma, chronic open angle glaucoma which was most common, were 14 eyes(66.7%); chronic angle closure glaucoma, 5 eyes(23.8%); aphakic glaucoma, 1 eye(4.8%); secondary glaucoma, 1 eye(4.8%). 3. Visual acuity improved in 20 eyes but unchanged in 1 eye, and 14 eyes(66.7%) achieved visual acuity 0.5 or better. 4. Preoperative mean intraocular pressure(IOP)was 20.9mmHg and postoperative mean IOP was 6.1, 4.5mmHg lower than preoperative level at 2 and 6 months res pectively. 5. 2.1 glaucoma medications was needed preoperatively and 0.7, 0.8 was needed at postoperative 2 and 6 months respectively. 6. There were no serious complications that affected the visual acuity. However minor complications were as follows. Hyphema were 4 eyes(19.0%); mydriasis, 3 eyes(14.3%); flat chamber, 1 eye(14.3%); flat chamber, 1 eye(4.8%); cystoid macular edema, 1 eye(4.8%).
