[Explantation of Multifocal Intraoular Lenses - Frequency, Causes and Course]
Klinische Monatsblatter Fur Augenheilkunde
|July 8, 2016
Summary
Multifocal intraocular lenses (MF-IOL) are generally well-accepted, with explantation needed in less than 1% of cases. Explantations due to optical discomfort were rare, occurring in only 0.28% of patients.
Area of Science:
- Ophthalmology
- Biomedical Engineering
Background:
- Multifocal intraocular lenses (MF-IOL) are utilized for visual rehabilitation following cataract surgery and refractive lens exchange (RLE).
- This study investigates the frequency, causes, and outcomes of MF-IOL explantation.
Observation:
- A retrospective analysis of 1438 eyes implanted with Acrysof ReSTOR MF-IOLs between 2009 and 2014 was conducted.
- The overall explantation rate was 0.83%, with 78% of implants for cataract and 22% for RLE.
Findings:
- Explantation was required in 12 cases (0.83%), with causes including refractive surprises, epiretinal gliosis, optical discomfort (0.28%), zonulolysis, and late-onset glistening.
- Causes unrelated to optical geometry accounted for the majority of explantations.
Implications:
- Diffractive MF-IOLs demonstrate good patient acceptance and a low rate of explantation due to optical issues.
- Full visual acuity recovery was achieved in all cases 12 months post-explantation.

01:25Glaucoma: Overview
1.6K
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...

01:16Focusing of Light in the Eye
7.0K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

01:28Angle Closure Glaucoma: Treatment
1.5K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:27Open Angle Glaucoma: Treatment
1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

10.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
