Abstract:
Small-incision cataract surgery widens the scope of combined cataract and glaucoma surgery. Phacoemulsification is gaining in importance, although extracapsular extraction techniques are still commonly used. Trabeculectomy remains the standard filtration operation combined with cataract surgery. There are currently a number of areas of contention in combined trabeculectomy surgery, including-the use of shared or separate incisions, the use of antimetabolities, and the type of intraocular implant. Other adjunctive procedures such as trabeculotomy and endocyclophotocoagulation are also discussed in the context of combined surgery.
