Angle-closure glaucoma: surgically remove the lens

When the iris (colored portion) of the inner eye contacts the focusing lens of the eye, thus blocking drainage of fluid from the eye, elevated fluid pressure (glaucoma) results.  This is known as angle-closure glaucoma.  This condition is often treated by making a small hole in the iris with a laser beam as a pressure-relieving measure.  However a recent study shows the most effective way to treat this form of glaucoma is to surgically remove the crystalline focusing lens of the eye (cataract surgery without a cataract).  This is a landmark change in therapy for angle-closure glaucoma.
