Endothelial damage from intraocular lens insertion
Investigative Ophthalmology
|December 1, 1976
Summary
Corneal endothelial cell loss during intraocular lens insertion can be reduced. Modifying the lens surface may prevent cell damage caused by the methacrylate material's interaction with eye tissues.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Cell Biology
Background:
- Intraocular lens (IOL) insertion is a common surgical procedure.
- Significant corneal endothelial cell loss (approximately 40%) occurs during IOL insertion.
- The methacrylate surface of IOLs causes cell adhesion and damage upon separation.
Purpose of the Study:
- To investigate the cause of corneal endothelial cell damage during IOL insertion.
- To explore methods for preventing cell damage by altering IOL surfaces.
Main Methods:
- Review of previous studies on IOL insertion and corneal cell damage.
- Analysis of the biophysical interaction between methacrylate IOL surfaces and corneal endothelial cells.
Main Results:
- Corneal endothelial cell damage is attributed to adhesion and separation from the methacrylate IOL surface.
- This damage is a result of a biophysical interaction between the lens and cells.
Conclusions:
- Corneal endothelial cell damage during IOL insertion is linked to the material properties of the lens.
- Altering the IOL surface may offer a strategy to mitigate or avoid this intraoperative cell loss.

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...
01:27Open 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.

01:28Angle 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...
