Purpose
To retrospectively evaluate visual performance in eyes with implantation of wavefront shaping extended depth-of-focus intraocular lenses (EDOF IOLs) after laser in situ keratomileusis (LASIK).
Setting
Tokyo Dental College Suidobashi Hospital
Methods
Clinical records of 32 eyes of 29 patients who received wavefront shaping EDOF IOLs (CNAET0, Alcon) after myopic LASIK (Group L; 13 eyes of 12 patients) and without previous LASIK (Group C; 19 eyes of 17 patients), were reviewed. All cases had preoperative corneal astigmatism ≤ 1.5D, since toric models were not available. LASIK had been performed at other sites 10 to 20 years ago so historical data was not available. Evaluations one month after surgery included uncorrected and distance-corrected visual acuities (VAs) at 5m, 60cm, and 40cm, photopic contrast sensitivity, the symptoms of night glare, halo, and starburst, as well as the usage of spectacles.
Results
The mean uncorrected (corrected) logMAR VAs for Group L/Group C were 5m: -0.04 (-0.150) / -0.07 (-0.157), 60cm: 0.019 (0.019) / 0.046 (0.050), 40cm: 0.126 (0.204) / 0.200 (0.324). Contrast sensitivities were within the normal range for all spatial frequencies in both groups. No significant differences were observed between groups in VAs, contrast sensitivity, the symptoms of glare and halo, and spectacle usages (p > 0.05). Starburst was more prevalent in Group L (P = 0.038).
Conclusions
Wavefront shaping EDOF IOL(CNAET0) provides excellent VAs from distance to intermediate ranges in post-LASIK eyes. However, a higher incidence of starburst phenomena suggests the need for careful patient counseling.
