Abstract Details

Purpose:

Use a patient questionnaire and multivariate regression analysis to compare and contrast functional visual outcomes and levels of patient satisfaction of post LASIK patients having received multifocal IOLs vs. EDOF vs. monofocal intraocular lenses.

Setting:

Bucci Laser Vision Institute Wilkes-Barre, PA USA

Methods:

Three cohorts of 61 post LASIK eyes were analyzed: 35 multifocal (+3.25 ZLB00), 11 EDOF IOLs (Symfony 9/Symfony toric 2), and 15 monofocals IOLs (Tecnis aspheric 8/Akreos 7) were retrospectively evaluated. A 19-question patient questionnaire was administered to evaluate subjective patient responses with regard to halos, glare, starburst, UDVA, intermediate, and near visual outcomes. 31 objective metrics including preop spherical equivalent, angle kappa, visual aberrations, pupil size, UCVA, reading speed & accuracy, postop residual astigmatism, and spherical equivalent will also be evaluated. The 50 objective and subjective variables were regressed against “overall patient satisfaction” to identify predictors of patient satisfaction.

Results:

All patients were either very satisfied or satisfied, but a significantly greater percent was very satisfied in the MULTI & EDOF cohorts: (MULTI 28/4, EDOF 9/2, MONO 4/9). Regression revealed that near visual function variables explained greater patient satisfaction in the MULTI (+3.25) vs EDOF & MONO cohorts including UCNVA p=.001, UCIVA p=.04, reading acuity p=.014, reading speed-WPM p=.05, glasses use-near p=.0014, reading newspaper p=.002. EDOF outperformed MONO for working on a computer p=.039. Contrast sensitivity was significantly less for MULTI vs both EDOF p=.05 and MONO p=.009. All 61 post LASIK eyes revealed significantly greater HOAs vs a cohort of 350 nonpost LASIK presbyopic IOL eyes: RMS p=.009, coma p=.038, trefoil p=.049, and spherical aberration p=.011.

Conclusions:

1)Multifocal IOLs achieved high levels of patient satisfaction in post LASIK patients despite lower scores for contrast sensitivity and HOAs. 2) Regression revealed that numerous variables related to uncorrected near visual function explained the high levels of patient satisfaction. 3) Halo, glare, and starburst did not contribute significantly to scores for patient satisfaction. 4) With proper patient selection multifocal IOLs are a viable IOL choice for cataract patients who have previously undergone LASIK.
