Summary
Secondary implantation of iris-claw lenses (Artisan IOL) effectively corrects aphakia. This safe and predictable method offers improved visual acuity and is preferred over anterior chamber and sclera-fixated IOLs.
Area of Science:
- Ophthalmology
- Intraocular Lens Implantation
- Refractive Surgery
Context:
- Aphakia presents a significant challenge in visual rehabilitation.
- Secondary intraocular lens (IOL) implantation is often necessary for aphakic eyes.
- Iris-claw lenses offer an alternative fixation method when other IOLs are unsuitable.
Purpose:
- To evaluate the safety and efficacy of secondary implantation of retroiridally fixated iris-claw lenses (Artisan IOL) for correcting aphakia.
- To compare the outcomes of Artisan IOL implantation with other IOL types.
Summary:
- A retrospective study analyzed 48 eyes of 46 patients undergoing secondary Artisan IOL implantation for various causes of aphakia.
- Procedures included anterior vitrectomy, IOL removal, and keratoplasty in some cases, with a mean follow-up of 14.3 months.
- Mean postoperative refraction was 0 dpt, and visual acuity improved significantly (median Log-Mar from 0.4 to 0.2), with normal intraocular pressures and few complications.
Impact:
- Retoiridally fixated Artisan IOLs are a safe and predictable option for correcting aphakia.
- This method demonstrates superior outcomes compared to anterior chamber IOLs and sclera-fixated IOLs.
- The study establishes Artisan IOL implantation as a preferred choice for secondary correction of aphakia.

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...
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.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
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...
