Cataract Clinical Trial
Official title:
Longtime Efficiency of Combined Cataract-Surgery and Excimer-Laser-Trabeculotomy or Trabectome in Glaucoma Surgery
This study compares efficacy (i.e. IOP and hypotensive medications) of phaco alone vs. combined phaco plus excimer laser trabeculotomy vs. combined phaco plus trabectome.
Glaucoma is one of the most common reasons for blindness. Usually an elevated drain
resistance is the reason, while aqueous humor production is normal. Medical reduction of
intraocular pressure (IOP) is first line therapy in most cases. The gold standard of surgical
treatment still is trabeculectomy (TE) but TE has a lot of drawbacks. In particular when
glaucoma and cataract coexists, the investigators therefore prefer the combined procedure
cataract extraction plus excimer laser trabeculotomy (ELT) or plus Trabectome. Indication is
cataract and a moderate elevated IOP without medical therapy or a moderate cataract and
elevated IOP with medical therapy.
The ELT is performed by an AIDA XeCl-Excimer Laser System (TUI-Laser AG, Germering, 1,2 mJ
per burst, burst duration 16 ns, wave length 308 nm, spot diameter 200 µm). 10 foramina were
made over 90 degrees of the anterior chamber angle. Trabectome procedure is performed with
the Trabectome unit from Neomedix.
