Summary
Neodymium:YAG laser capsulotomy effectively treated late capsular block syndrome (CBS) causing decreased vision due to posterior capsule opacification (PCO). This procedure improved visual acuity without significant changes in refraction or intraocular pressure.
Area of Science:
- Ophthalmology
- Surgical Procedures
- Laser Treatments
Background:
- Late postoperative capsular block syndrome (CBS) can cause decreased vision due to posterior capsule opacification (PCO).
- Capsular block syndrome may remain undiagnosed for extended periods after cataract surgery.
- Phacoemulsification with intraocular lens implantation is a common cataract surgery technique.
Purpose of the Study:
- To evaluate the efficacy of neodymium:YAG (Nd:YAG) laser capsulotomy for late CBS with vision loss from PCO.
- To assess changes in refraction, visual acuity, intraocular pressure (IOP), and complications post-Nd:YAG laser capsulotomy.
Main Methods:
- Retrospective review of patients with CBS post-phacoemulsification and intraocular lens implantation.
- Treatment with Nd:YAG laser capsulotomy for PCO-related vision decrease.
- Evaluation of refraction, corrected distance visual acuity (CDVA), IOP, and complications at multiple follow-up intervals.
Main Results:
- Nd:YAG laser capsulotomy was successful in all treated eyes.
- Visual acuity improved significantly post-procedure (mean logMAR CDVA improvement of 0.26).
- No significant changes in refraction or intraocular pressure were observed; no complications or inflammation occurred.
Conclusions:
- Nd:YAG laser capsulotomy is a safe and effective treatment for late CBS with PCO, restoring visual acuity.
- CBS can be a long-standing, asymptomatic condition preceding PCO development.
- Ophthalmologists should consider delayed CBS in patients with unexplained vision decline after cataract surgery.

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
