For patients who have both poorly controlled glaucoma and cataracts, a combined surgery may be suggested. If the cataract is visually significant it is usually desirable to perform the cataract surgery first if the glaucoma is not completely uncontrolled. Not only can removal of the cataract occasionally result in a modest lowering of the eye pressure in itself, having this done first can allow for better long-term success of a subsequent glaucoma surgery.
For patients who have controlled glaucoma and cataracts, cataract surgery with an IOL implant may be the best option. In most cases, these patients will continue with their glaucoma medications after cataract surgery.
