Summary
Acrysof toric intraocular lenses effectively correct astigmatism, achieving good uncorrected and best corrected visual acuity with minimal lens rotation. These results demonstrate a high success rate in patients undergoing cataract surgery.
Area of Science:
- Ophthalmology
- Biomedical Engineering
Background:
- Astigmatism is a common refractive error impacting visual quality.
- Toric intraocular lenses (IOLs) are designed to correct astigmatism during cataract surgery.
Purpose of the Study:
- To evaluate the medium-term outcomes of Acrysof toric intraocular lens implantation.
- To assess visual acuity, refractive error correction, and IOL rotation.
Main Methods:
- Study included 54 patients (54 eyes) implanted with Acrysof toric IOLs.
- Evaluated uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and pre- and postoperative astigmatism.
- Analyzed intraocular lens (IOL) rotation grade for different models (T3, T4, T5).
Main Results:
- Mean UCVA was 0.83 and mean BCVA was 0.94 at 2 months.
- Preoperative astigmatism (-2.25 D) was significantly reduced to -0.32 D postoperatively.
- Mean IOL rotation was 3.87°, with 91.6% within 10° of the predicted axis.
Conclusions:
- Acrysof toric IOLs (T3, T4, T5) successfully correct preoperative astigmatism.
- High success rates were observed in UCVA and residual astigmatism.
- Minimal IOL rotation was noted at the 2-month follow-up.

Angle 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...
Open 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.
