As of 2015, studies show that a cataract surgery performed close to the time of a trabeculectomy may have an adverse effect on the latter procedure, according to EyeNet Magazine. Some doctors may also prefer to address both conditions in a single procedure. Both doctors and patients should carefully weigh the risks of a combined procedure.

Cataract surgery may also be combined with other procedures for glaucoma, such as endocyclophotocoagulation, canaloplasty and micro-invasive glaucoma surgeries, as affirmed by the Glaucoma Research Foundation. Micro-invasive glaucoma surgeries may be especially suited for combination surgery as the same incision may be used to remove the cataract. Cataract surgery alone may be an option when the cataract becomes too large and crowds other eye structures.

Cataracts may cause glaucoma, occur as a result of glaucoma or coexist naturally with the condition, as stated by the Glaucoma Research Foundation. Glaucoma patients may experience a spike in eye pressure after undergoing cataract surgery, and they are more susceptible to damage from a transient pressure increase after the procedure.
