Summary
Intraocular lens (IOL) waste occurs infrequently but incurs significant costs, particularly with polymethyl methacrylate (PMMA) materials and specific designs. Damage is the leading cause, highlighting the need for waste reduction strategies.
Area of Science:
- Ophthalmology
- Healthcare Economics
- Surgical Waste Management
Background:
- Cataract surgery involves intraocular lens (IOL) implantation, a critical step with potential for material waste.
- Understanding the economic and logistical impact of IOL waste is essential for optimizing surgical resource allocation.
Purpose of the Study:
- To determine the incidence and financial cost of intraocular lens (IOL) waste.
- To identify specific IOL properties and procedural factors contributing to waste.
- To analyze the primary causes of IOL wastage during implantation.
Main Methods:
- Retrospective analysis of IOL waste registers from a tertiary eye hospital in China (2016-2020).
- Inclusion of 485 cases of IOL waste from 73,246 implantations.
- Examination of IOL material, design, procedural details, and reasons for waste.
Main Results:
- IOL waste occurred in 6.62‰ of implantations, with a total cost of 429,850.26 CNY.
- Polymethyl methacrylate (PMMA) material, three-piece designs, and secondary implantations were significantly associated with higher waste rates.
- Damage (60.80%) was the primary cause of waste, followed by patient reasons (21.26%) and aseptic errors (12.50%).
Conclusions:
- While the incidence of IOL waste is low, it represents a substantial financial burden.
- Specific IOL types (PMMA, three-piece) and secondary implantations increase waste.
- Damage, often due to human error, is the main driver of IOL waste, necessitating targeted mitigation strategies.

01:25Glaucoma: Overview
548
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
479
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
430
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.
