5. Study Description
Brief Summary
The aim of this study is to evaluate the efficacy of selective laser trabeculoplasty after a prior failed phacoemulsification and Eximer Laser Trabeculectomy.
Detailed Description
This study evaluates the efficacy of selective laser trabeculoplasty after a failed combined procedure of phacoemulsification cataract extraction with intraocular lens implantation plus Eximer Laser Trabeculectomy in open angle glaucoma or ocular hypertension. The success of SLT will be determined by the intraocular pressure and number of hypotensive drugs.
