Purpose:
To evaluate optical and visual quality differences after Implantable Collamer Lenses (ICLs) implantation and femtosecond laser in situ keratomileusis (F-LASIK) procedure for two degrees of myopia (-3 and -6 Diopters (D)).
Setting:
University of Valencia, Spain
Methods:
We used an adaptive optics visual simulator (crx1, Imagine Eyes, France) to simulate the wavefront aberration patterns induced by F-LASIK procedure for -3D and -6D and the wavefront pattern of an ICL of -3.00D and -6.00D. Visual acuity (VA) at different contrasts (high (100%), medium (50%) and low (10%)) and contrast sensitivity function (CSF) at 10, 20 and 25 cycles/degree (cpd) frequencies were measured for 3 and 5-mm pupils. Modulation Transfer Function (MTF) and Point Spread Function (PSF) were calculated for a 5-mm pupil.
Results:
Ten subjects were enrolled in this study. For 3mm of pupil size, ICL provides better VAs values and CSF at all frequencies studied than F-LASIK for -3D and -6D (P< 0.05). At the same time, for 6 mm of pupil diameter, the best VAs and CSF values for both refractive errors were obtained with the ICL (P< 0.05). The F-LASIK MTF was worse than the ICL MTF which was close to the diffraction-limited MTF. The ICL showed less spread out of PSF than the F-LASIK treatment.
Conclusions:
ICL implantation and F-LASIK procedure provide good optical and visual quality, although ICLs provide better outcomes, especially for higher refractive errors and pupil sizes. FINANCIAL DISCLOSURE?: No
