Sažetak

Persistent pupillary membrane (PPM) is a consequence of incomplete involution and atrophy of the pupillary membrane. Most PPMs require no treatment because they rarely cause visual impairment. Remnant structures vary from a few non-pigmented threads to a thick membrane covering the entire pupil. The aim of this case report is to show the advantages of Nd-YAG laser lysis of PPM prior to phacoemulsification cataract surgery. We describe a case of a patient with bilateral PPM and cataract of the right eye having significant visual loss in bright light that underwent Nd-YAG laser lysis and experienced visual acuity improvement from 0.1 to 0.9 after phacoemulsification surgery, without any complications. We conclude that in PPM patients scheduled for cataract surgery, laser lysis of PPM prior to cataract surgery is preferable to surgical excision of PPM that is associated with complications such as infection, hyphema, and risk of anesthesia. Laser lysis of pupillary membranes is a relatively simple procedure. There is less discomfort than with surgical excision, and the procedure results in a perfectly round pupil, thus facilitating cataract surgery while also preventing intraoperative hemorrhage during surgical excision that may complicate the scheduled phacoemulsification cataract surgery.
