Summary
This study shows that unilateral implantation of the LENTIS Mplus multifocal intraocular lens (IOL) after cataract surgery or refractive lens exchange (RLE) provides good vision at all distances with minimal side effects.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Intraocular Lenses
Background:
- Cataract surgery and refractive lens exchange (RLE) aim to restore vision.
- Multifocal intraocular lenses (IOLs) are used to correct refractive errors and presbyopia.
- Rotationally asymmetric IOL designs may offer improved visual outcomes.
Purpose of the Study:
- To evaluate visual, refractive, and quality-of-vision outcomes after unilateral cataract surgery or RLE.
- To assess the performance of the LENTIS Mplus LS-313 MF30 and LENTIS MplusX multifocal IOLs.
Main Methods:
- Thirty-nine patients underwent unilateral lens extraction with LENTIS Mplus multifocal IOL implantation.
- Visual acuity (distance, intermediate, near), refraction, contrast sensitivity, and Quality of Vision were assessed.
- Defocus curves and wavefront aberrations were analyzed.
Main Results:
- Mean uncorrected and corrected distance visual acuity were excellent.
- Good uncorrected and corrected near and intermediate visual acuity were achieved.
- Defocus curves showed broad functional vision, with generally mild visual disturbances reported.
Conclusions:
- Unilateral implantation of the LENTIS Mplus multifocal IOL was well tolerated.
- Favorable monocular and binocular performance was observed.
- High refractive predictability and minimal optical side effects were noted.
