Visual Outcomes, Patient Satisfaction, and Light Distortion Analysis After Blended Implantation of Rotationally...

Area of Science:

• Ophthalmology
• Refractive Surgery
• Optics

Background:

• Multifocal intraocular lenses (IOLs) aim to provide clear vision at multiple distances.
• Rotationally asymmetric IOL designs offer unique visual performance characteristics.
• Blended IOL implantation involves using lenses with different refractive powers to optimize binocular vision.

Purpose of the Study:

• To evaluate visual outcomes and patient satisfaction following blended implantation of asymmetric multifocal IOLs.
• Assessing the efficacy of combining +3.00 D and +1.50 D LENTIS Mplus LS-313 IOLs.

Main Methods:

• Prospective interventional study involving 40 eyes of 20 patients undergoing refractive lens exchange.
• Patients received blended IOL implantation: +3.00 D in the non-dominant eye and +1.50 D in the dominant eye.
• Visual acuity, defocus curves, contrast sensitivity, light distortion analysis, aberrometry, and patient satisfaction (NAVQ-10) were assessed 12 months post-surgery.

Main Results:

• Significant improvement in uncorrected distance visual acuity post-surgery (P < .001).
• Good uncorrected near and intermediate visual acuity achieved (0.18 and 0.38 logMAR).
• Binocular assessment showed superior contrast sensitivity and light distortion analysis compared to monocular results. Higher-order aberrations were higher in the +3.00 D eye.

Conclusions:

• Binocular visual outcomes, defocus curve, light distortion analysis, and contrast sensitivity were significantly better than monocular measures.
• Blended IOL implantation with varying near additions enhances binocular visual performance and patient satisfaction.
• This strategy effectively leverages the advantages of each IOL for improved overall visual function.
