Summary
This study presents a new technique for suturing dislocated intraocular lenses (IOLs) using 25-gauge (G) instruments. The described method, 25-gauge transconjunctival sutureless vitrectomy (25G-TSV), offers a safe and effective solution for IOL fixation.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Intraocular Lens Implantation
Background:
- Dislocated intraocular lenses (IOLs) pose a surgical challenge.
- Current methods for IOL repositioning may have limitations.
Purpose of the Study:
- To describe a novel technique for suturing dislocated IOLs.
- To evaluate the safety and efficacy of using 25-gauge (G) instruments for IOL fixation.
Main Methods:
- A case series of five patients with dislocated IOLs was conducted.
- The technique involved 25-gauge transconjunctival sutureless vitrectomy (25G-TSV) with temporary haptic externalization.
- Perfluorocarbon liquid was used to manage IOLs within the lens capsule.
Main Results:
- Stable IOL fixation and optimal positioning were achieved in all cases.
- Best-corrected visual acuity improved or was maintained post-surgery.
- No major intraoperative or postoperative complications were observed, barring one instance of iris capture.
Conclusions:
- 25-gauge transconjunctival sutureless vitrectomy (25G-TSV) is a practical and safe approach for fixating dislocated IOLs.
- This technique demonstrates potential for successful visual recovery and IOL stability.

1.1K
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...

1.2K
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.
