The Intraocular Lens: Challenges in the Prevention and Therapy of Infectious Endophthalmitis and Posterior Capsular Opacification

Expert Review of Medical Devices, 2005
Cataract is the leading cause of visual impairment worldwide. In the UK, some 30% of the population over 65 years of age have visually impairing cataract.

Misdiagnosed opacification of a hydrophobic acrylic intraocular lens

Journal of Cataract and Refractive Surgery, 2019
A 75-year-old woman was referred for decreased visual acuity resulting from "opacification of the IOL" in the immediate period after uneventful bilateral cataract surgery with single-piece AcrySof IQ intraocular lens (IOL) implantation. A neodymium:YAG laser capsulotomy had been performed in both eyes to treat the complication. Anterior segment optical

Opacification of Artificial Intraocular Lens: An Electron Microscopic Study

Ultrastructural Pathology, 2001
This paper describes the usefulness of electron microscopy in the investigation of the cause of opacification of an intraocular artificial lens (IOL), which affected both the anterior and posterior surfaces of the IOL. The explanted lenses were remarkably similar and were uniformly opaque, with "reticulated" surfaces under dissecting and ordinary light

Opacification of intraocular lens

Acta Ophthalmologica, 2015
SummarySoft hydrophobic acrylic intraocular lenses (IOLs) are increasingly being used because they can be implanted through small incisions, provide good postoperative vision. However, long‐term postoperative follow‐up has identified various problems, including calcification, glistening and whitening.Calcium deposit on surface of IOLs are sometimes ...

Reversible opacification of a hydrophilic acrylic intraocular lens

Journal of Cataract and Refractive Surgery, 2012
A 56-year-old woman with diabetic retinopathy and chronic myelogenous leukemia had phacoemulsification cataract removal and hydrophilic acrylic intraocular lens (IOL) (Akreos MI-60) implantation in both eyes. One month after surgery, significant IOL opacity and severe cystoid macular edema were observed in both eyes.

Causes of intraocular lens opacification or discoloration

Journal of Cataract and Refractive Surgery, 2007
Various pathologic processes may lead to clinically significant opacification or discoloration of the optic component of intraocular lenses (IOLs) manufactured from different biomaterials and in different designs. Factors such as the patient's associated conditions, the manufacturing process, the method of IOL storage, the surgical technique and ...

Opacification of Array SA40N silicone multifocal intraocular lens

Journal of Cataract and Refractive Surgery, 2007
We report opacification of 2 multifocal intraocular lenses (IOLs). Patients with these IOLs may be more likely to require IOL explantation than those with monofocal IOLs.

Effect of intraocular lens convexity on posterior capsule opacification

Journal of Cataract and Refractive Surgery, 1986
A consecutive series of 248 eyes undergoing extracapsular cataract surgery and posterior chamber lens implantation were evaluated. One hundred eight eyes had the implant placed with the convex side posterior and 140 with the convex side anterior. The incidence of capsulotomy required in the convex posterior group was significantly less than in the ...

Large-scale opacification of a hydrophilic/hydrophobic intraocular lens

European Journal of Ophthalmology, 2019
Purpose: To determine the prevalence and risk factors related to the opacification of the LS-502-1 intraocular lens. Methods: Cross-sectional study including patients submitted to cataract surgery between January 2010 and March 2012 ...
