A new procedure for the treatment of uncontrolled aphakic glaucoma has been the subject of a carefully conducted prospective clinical trial in 14 patients. The study spanned more than five years. The transpupillary argon laser photocoagulation of the ciliary process procedure, done on an outpatient basis, shows promise as a convenient, low-risk, and useful alternative procedure in selected aphakic glaucoma cases that are poorly controlled by medical or surgical measures. This new approach may also be used as an adjunct in the medical and/or surgical management of aphakic ciliary block glaucoma. The magnitude of intraocular pressure reduction is directly related to the number of ciliary processes coagulated and the level of laser energy applied. The indications for this new procedure are generally similar to that of the cyclocryotherapy.
