In eyes with normal corneas, DCT allows suitable and reliable IOP measurements which are in good concordance with GAT. Comparison of DCT with intracameral manometry is desirable in the future.

ELT, especially in combination with phacoemulsification, is a new, promising, minimally invasive laser treatment to reduce IOP for at least 1-2 years. ELT alone is less effective in IOP reduction.

ELT is a promising IOP-lowering technique both as a stand-alone procedure and in combination with cataract surgery. It is especially suitable for patients with high preoperative IOP levels.

After 3 years follow-up of a small pilot group, combined endoscopic infrared laser surgery with cataract surgery seems to be a safe and effective way to lower IOP. It shows the same ability to lower IOP as combined cataract surgery with trabeculectomy. In addition, there are markedly less complications with the endoscope-controlled photo-ablative laser procedure.
