Summary
A case report details Toric Lentis Mplus intraocular lens (IOL) opacification due to calcium deposits after vitrectomy in a high myopia patient. Hydrophilic acrylic IOLs require caution in such cases.
Area of Science:
- Ophthalmology
- Biomaterials Science
Background:
- A 44-year-old male with high myopia and a history of optic neuritis presented with visual impairment due to cataract.
- Phacoemulsification and implantation of a Toric Lentis Mplus intraocular lens (IOL) were performed on the right eye.
Observation:
- Six months post-implantation, the patient developed a nasal retinal detachment, necessitating a 25-gauge vitrectomy with gas tamponade and endolaser treatment.
- Ten months after vitrectomy, the patient reported blurred vision; slit-lamp examination revealed opacification on the anterior surface of the IOL.
Findings:
- The explanted Toric Lentis Mplus IOL showed calcium aggregate deposits on its anterior surface.
- Microscopic examination confirmed the presence of these calcium deposits.
Implications:
- This case highlights the potential for hydrophilic acrylic IOL opacification, specifically the Toric Lentis Mplus IOL, following vitrectomy in patients with high myopia.
- Caution is advised when using hydrophilic acrylic IOLs in patients with high myopia and younger individuals due to a higher incidence of fundus diseases.
- This is the first reported instance of Toric Lentis Mplus IOL opacification post-vitrectomy, following a 2017 Field Safety Notice.

01:25Glaucoma: Overview
1.1K
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
1.0K
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
887
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.
