Dissatisfaction After Trifocal IOL Implantation and Its Improvement by Selective Wavefront-Guided LASIK

Area of Science:

• Ophthalmology
• Refractive Surgery
• Optometry

Background:

• Trifocal intraocular lenses (IOLs) aim to improve vision at multiple distances but can sometimes lead to dissatisfaction due to residual refractive errors.
• Wavefront-guided laser in situ keratomileusis (LASIK) offers a potential solution for correcting aberrations and improving visual outcomes.

Purpose of the Study:

• To assess an improved wavefront acquisition technique for selective wavefront-guided aberration correction.
• To enhance patient satisfaction following trifocal IOL implantation.

Main Methods:

• A cohort of dissatisfied patients (56 eyes) who received trifocal IOLs underwent selective wavefront-guided LASIK.
• The procedure corrected all aberrations except spherical aberrations to maintain multifocal IOL performance.
• Patient satisfaction and refractive outcomes were evaluated over a 12-month follow-up period.

Main Results:

• Selective wavefront-guided LASIK achieved the refractive target (±0.50 D) in 98% of eyes and reduced refractive astigmatism to ≤0.50 D in 93%.
• Overall patient satisfaction scores increased significantly from 2.1 to 3.6 (on a 4-point scale).
• Eighty-eight percent of initially dissatisfied patients would opt for the procedure again.

Conclusions:

• Selective wavefront-guided LASIK effectively reduces refractive errors and improves spectacle independence.
• This technique significantly enhances patient satisfaction, potentially leading to greater acceptance of trifocal IOLs.
