Summary
Extended depth of focus (EDOF) intraocular lenses (IOLs) may cause sensorimotor disturbances like diplopia. This report details two cases of EDOF IOLs leading to vision issues, highlighting potential risks for specific patient groups.
Area of Science:
- Ophthalmology
- Neuroscience
Background:
- Cataracts are a leading cause of reversible blindness globally.
- The incidence of cataracts is projected to rise significantly by 2050, increasing the demand for cataract surgery.
- Extended Depth of Focus (EDOF) intraocular lenses (IOLs) are a novel technology approved in 2016, offering enhanced intermediate vision.
Purpose of the Study:
- To investigate potential sensorimotor decompensation risks associated with EDOF IOL implantation.
- To report two cases of sensorimotor disturbances following bilateral EDOF IOL implantation.
Main Methods:
- Case report describing two patients who developed sensorimotor disturbances after EDOF IOL surgery.
- Review of existing literature on sensorimotor complications following cataract surgery and multifocal IOL implantation.
Main Results:
- One patient with a history of accommodative esotropia experienced decompensation of stereopsis post-operatively.
- Another patient developed new-onset vertical diplopia after bilateral EDOF IOL implantation.
Conclusions:
- EDOF IOLs, while offering visual benefits, may be associated with sensorimotor decompensation in susceptible individuals.
- Further research is needed to understand the risks of EDOF IOLs in patients with pre-existing binocular vision anomalies.

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...
01:28Angle Closure Glaucoma: Treatment
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...
01:16Focusing of Light in the Eye
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...
01:27Open Angle Glaucoma: Treatment
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.

01:15Depth Perception and Spatial Vision
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.
