Summary
The I-CARE phakic intraocular lens (IOL) for high myopia correction led to significant endothelial cell loss and serious adverse events, necessitating regular monitoring and timely explantation.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Intraocular Lenses
Background:
- High myopia presents significant visual challenges.
- Phakic intraocular lenses (IOLs) offer a surgical option for correcting high myopia.
- The I-CARE anterior-chamber angle-supported phakic IOL is one such device.
Purpose of the Study:
- To evaluate the visual quality and postoperative outcomes.
- To assess adverse events associated with I-CARE phakic IOL implantation in myopic patients.
- To determine the safety and efficacy of this specific IOL model.
Main Methods:
- A retrospective case series analysis of 29 eyes (16 patients) with high myopia.
- Data collected included visual acuity, slit-lamp examination, corneal topography, Scheimpflug imaging, and endothelial cell (EC) counts.
- Follow-up averaged 51.7 months post-implantation.
Main Results:
- Mean best-corrected visual acuity (BCVA) improved to 0.94 decimal after one year.
- Significant endothelial cell loss was observed, reaching 47% by 6 years post-implantation.
- Eight IOL explantations were required due to severe EC loss; one case of Urrets-Zavalia Syndrome occurred.
Conclusions:
- I-CARE phakic IOL implantation is not a safe method for high myopia correction due to substantial endothelial cell loss.
- Close patient monitoring (at least every 6 months) is crucial.
- Explantation is recommended when endothelial cell count drops below 2000 cells/mm².

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...
