If a patient is having a hyperopic ICL they will need to have a peripheral iridotomy (PI) either prior to surgery or on the day of surgery.

The major complication reported is pupillary block (7.7%), which can be prevented and managed with the use of cycloplegics, prophylactic laser iridotomy, oral and topical antiglaucoma drugs, or a partial fill of AC with air or gas.

Group 2 included patients with high intraocular pressure (over 21 mmHg), narrow ACA detected by gonioscopy, glaucomatous optic nerve head changes (notching of optic disc rim, higher vertical cup-to-disc ratio, retinal nerve fiber layer hemorrhages), glaucomatous visual field defects (scotomas indicating loss of the nerve fiber layer), and no history of laser peripheral iridotomy. Inclusion criteria for group 3 were normal intraocular pressure (under 21 mmHg) and no abnormal findings in anterior segment, fundus, or visual field examinations.
