Toric Aberrometric Extended Depth of Focus Intraocular Lens: Visual Outcomes, Rotational Stability, Patients'...

Area of Science:

• Ophthalmology
• Optometry
• Biomedical Engineering

Background:

• Cataract surgery often requires correction for astigmatism.
• Toric intraocular lenses (IOLs) correct astigmatism, while extended depth of focus (EDOF) IOLs aim to improve vision at multiple distances.
• Combining these features in a Toric EDOF IOL may enhance visual outcomes and patient satisfaction.

Purpose of the Study:

• To evaluate visual outcomes, rotational stability, patient satisfaction, and spectacle independence after bilateral Toric EDOF IOL implantation.
• To assess the efficacy of Toric EDOF IOLs in correcting astigmatism and providing a full range of vision.

Main Methods:

• Prospective observational study involving cataract patients with astigmatism (0.75-3.00 D) who received bilateral Toric EDOF IOLs.
• Postoperative evaluation included visual acuity at various distances, IOL stability assessment, defocus curves, contrast sensitivity, and reading performance.
• Objective measures of visual quality, such as Strehl ratio and modulation transfer function, were also analyzed.

Main Results:

• Ninety percent of eyes achieved uncorrected distance visual acuity (UDVA) of 0.2 logMAR or better.
• High percentages of patients achieved good uncorrected intermediate (95%) and near (80%) visual acuity.
• The Toric EDOF IOL demonstrated excellent rotational stability, with no cases requiring repositioning surgery.

Conclusions:

• Bilateral Toric EDOF IOL implantation provides reliable astigmatic correction and good rotational stability.
• These IOLs offer significant spectacle independence and high patient satisfaction.
• The Toric EDOF IOL delivers effective visual performance across distance, intermediate, and near visual demands.
