Summary
This study compared two intraocular lenses (IOLs) in the modified Yamane technique, finding both safe and effective for aphakia and subluxated IOLs. Refractive outcomes varied, suggesting IOL-specific adjustments may be needed for emmetropia.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Biomaterials Science
Background:
- The modified Yamane technique offers a solution for complex cases like aphakia and dislocated intraocular lenses (IOLs).
- Evaluating different IOLs within this technique is crucial for optimizing patient outcomes.
- Polymethylmethacrylate (PMMA) haptic IOLs are commonly used in such complex reconstructions.
Purpose of the Study:
- To compare the efficacy and safety of Alcon MA60AC and Sensar AR40e IOLs in the modified Yamane technique.
- To assess visual acuity and refractive outcomes following the procedure.
- To identify potential complications associated with each IOL type.
Main Methods:
- A retrospective study involving 50 patients divided into two groups (n=25 each) receiving either Alcon MA60AC or Sensar AR40e IOLs.
- Surgical indications included aphakia and subluxated single-piece IOLs.
- Patients were evaluated preoperatively and at six months postoperatively for complications, visual acuity, and refractive outcomes.
Main Results:
- Both IOL groups showed significant improvements in visual acuity (p<0.05).
- Spherical refractive values differed significantly at six months (Group A: +0.75±0.48D, Group S: -0.56±0.49D, p=0.01).
- Deviation from target refraction was notably less in Group S (0.65±1.54D) compared to Group A (1.71±1.35D) (p<0.001).
Conclusions:
- The modified Yamane technique is effective and safe with PMMA haptic IOLs.
- Significant differences in refractive outcomes were observed between the two IOLs.
- Tailoring IOL selection or surgical targets may be necessary to achieve emmetropia with specific IOLs.

01:27Open Angle Glaucoma: Treatment
568
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
681
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...
