Complications After Incisional/Excisional Minimally Invasive Glaucoma Surgery-An Update and Literature Review.

PURPOSE: To discuss comprehensively the varied complications after stent-less incisional or excisional minimally invasive glaucoma surgery (MIGS).

METHOD: A review of reported complications after stent-less MIGS procedures including gonioscopy-assisted transluminal trabeculotomy (GATT), bent needle goniectomy (BANG), Kahook-dual blade goniotomy, and microincisional trabeculectomy (MIT) published between 2014-2024, were analyzed and summarized.

RESULTS

Apart from hyphema, peripheral anterior synechiae, and intraocular pressure spikes, other vision-threatening complications like cyclodialysis, Descemet's detachment, corneal edema, iridodilalysis, vitreous loss or vitreous hemorrhage can also occur intra- or postoperatively after any incisional or excisional MIGS procedures.

CONCLUSION

All possible complications are to be kept in mind during MIGS despite the procedures being minimally invasive. Adequate care should be taken during different stages of the surgery to avoid these complications.
