Quantitative Analysis of Gap Between the Intraocular Lens and Posterior Capsule Using Microscope-Integrated Optical Coherence Tomography in Eyes Undergoing Phacoemulsification

Purpose— to study the relations between the posterior capsule (PC) and intraocular lens (IOL) after cataract surgery in pseudoexfoliation syndrome (PEX).Patients and methods. We examined 46 eyes of 37 patients with PEX who underwent a standard and uncomplicated phacoemulsification. The age of patients was 60–94 years. Postoperative period ranged from 1 day to 10 years. An optical coherence tomography (OCT) (RTVue XR Avanti, “Optovue”) was used to image the IOL-PC space in early and late postoperative period.Results. In the first days full contact PC-IOL was not observed in any case. The maximum of space PC-IOL was noted on the first day postoperatively. Posterior capsule had a wavy or folded profile on the scans. In the next two weeks we observed a decrease of the distances between posterior capsule and IOL. After 1 month we noted the formation of capsular bend around optic edge, the full adhesion of posterior capsule to IOL was not detected. In the late postoperative period the fibroplastic and proliferative capsular changes with secondary discontact PC-IOL was noted. Primary inadhesion of a posterior capsule to IOL was recorded in half of the cases.и. High resolution OCT was suitable for quantitative analysis of IOL-PC space. Involution changes in structures of anterior segment in the eyes with PEX had a role in closure of the IOL-PC space. Complete adhesion of posterior capsule to IOL was not observed in the majority of eyes with PEX.

Accidental intraocular lens (IOL) implantation into the corneal stroma is a rare clinical entity that can occur during the wound-assisted technique. In this report, we describe a case of an 81-year-old man who underwent cataract surgery in which the IOL was implanted into the corneal stroma with the wound-assisted technique, and we present changes in anterior segment optical coherence tomography. The IOL was removed and reinserted after widening the incision. Air tamponade was created by intracameral injection. An anterior chamber tap was performed 10 h later to reduce increased intraocular pressure. Interlayer separation of the corneal stroma was confirmed 30 min postoperatively but was corrected 4 days later. The patient’s best-corrected visual acuity (BCVA) was logMAR 0.30, and he had been diagnosed with age-related macular degeneration before surgery. Although the opacity of the corneal stroma persisted, BCVA improved to logMAR 0. When using the wound-assisted technique for IOL insertion, surgeons should take care not to implant the IOL into the corneal stroma.
