Abstract Details

Purpose:

To evaluate visual performance in eyes with implantation of extended range of vision intraocular lenses (IOLs) after laser insitu ketratomileusis (LASIK).

Setting:

Department of Ophthalmology, Tokyo Dental College Suidobashi Hospital

Methods:

This retorospective study included 41 eyes of 25 patients who received extended range of vison IOLs (ZXR00, Johnson&Johnson Vision) after previous LASIK (L group; 23 eyes of 14 patients), and without LASIK (C group; 18 eyes of 11 patients). Uncorrected and distance corrected logMAR visual acuities (UCVA and DCVA, respectively) at 5m, 1m, and 50cm, and contrast sensitivity were assessed 3 months postoperatively.

Results:

The mean logMAR UCVAs (DCVAs) of E/L groups were -0.09 (-0.14)/-0.04 (-0.17) for 5m, 0.04 (-0.01)/-0.05 (-0.05) for 1m, and 0.16 (0.04)/0.13 (0.06) for 50cm. Although contrast sensitivities were within normal range in both group at all of special frequencies, C group was significantly better than L group at 18 cpd. (p = 0.03; unpaired t-test)

Conclusions:

Implantation of EDOF IOL, ZXR00, after LASIK provides excellent vision from far to intermediate distance, although there is slight concern about decrease of contrast sensitivity in high spatial frequency.
