Summary
Phakic intraocular lenses (IOLs) offer an alternative to laser vision correction for high refractive errors. While no single phakic IOL is safest, all provide visual benefits, with outcomes depending on anatomical effects and long-term monitoring.
Area of Science:
- Ophthalmology
- Biomaterials Science
Context:
- Growing concerns regarding secondary ectasia after photoablation (LASIK).
- Advancements in soft foldable biomaterials have revived interest in phakic intraocular lens (IOL) implantation.
- Phakic IOLs are implanted in front of the natural lens, categorized by anterior or posterior chamber placement.
Purpose:
- To review available phakic IOL models as of 2006 and those under evaluation.
- To discuss the advantages and limitations of different phakic IOL types.
- To deduce appropriate indications for phakic IOL use.
Summary:
- Two main types of phakic IOLs exist: anterior chamber and posterior chamber lenses.
- No single phakic IOL model demonstrates superior safety; all offer visual benefits and improved best-corrected visual acuity.
- Evaluation requires long-term follow-up to assess anatomical effects on the angles, lens, iris, and endothelium.
Impact:
- Provides a comprehensive overview of phakic IOLs for ophthalmologists and researchers.
- Informs clinical decision-making regarding the correction of high ametropia.
- Highlights the importance of long-term monitoring for anatomical effects and patient safety.

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...
