Are there any alternatives?

An alternative to laser treatment is a surgical lens extraction cataract operation, which is technically identical to cataract surgery. Although the risk is still low (less than 1 in 1000), lens extraction is usually only recommended for patients who are already developing visual problems from cataract, or for patients who are unlikely to benefit from laser treatment. Patients who choose not to have laser peripheral iridotomy or lens extraction treatment risk developing angle-closure or deterioration of established angle-closure, which can result in high intraocular pressure and loss of vision from glaucoma. Observation only is a reasonable option for patients who do not have high intraocular pressure or other signs of damage from angle-closure, and we would recommend having regular reviews by a local optometrist. There are no other alternatives to open up the drainage channels in your eye. Some patients with this condition also develop a long-term (chronic) rise in their eye pressure and may need drops or other treatments in the long-term to keep the eye pressure within safe limits.
