Femtosecond Laser-Assisted Cataract Surgery in a Patient with Persistent Pupillary Membrane

Background

Persistent pupillary membrane (PPM) is a condition of the eye involving remnants of a fetal membrane that persist as strands of tissue crossing the pupil. The pupillary membrane in mammals exists in the fetus as a source of blood supply for the lens. It normally atrophies from the time of birth to the age of 4 to 8 weeks. PPM occurs when this atrophy is incomplete. It generally does not cause any symptoms; however, it can be challenging during cataract surgery due to an increased risk of bleeding and reduced visibility [1], [2], [3], [4].
