Selective laser trabeculoplasty following failed combined phacoemulsification cataract extraction and excimer laser trabeculotomy can control intraocular pressure for a limited time.

In eyes in which the IOP is no longer controlled following phaco-ELT, SLT could be an option to slow disease progression or prolong time until incisional filtration surgery. However, time to failure after SLT is limited. Thus, close follow-up visits are necessary in order to not delay an incisional surgery.
