Abstract Details

Purpose:

to compare the outcomes of the wavefront-guided LASIK and standard LASIK methods in the treatment of induced refractive errors following penetrating keratoplasty (PKP).

Setting:

The S. Fyodorov Eye Microsurgery State Institution, Russia.

Methods:

we observed 32 eyes (32 patients) with residual ametropy after the PKP, out of which 14 eyes were operated by the wavefront-guided customized LASIK technology : group I, 18 eyes by the standard LASIK technology ;group II. The uncorrected (UDVA) and corrected (CDVA) visual acuities, manifest refraction and HOAs were recorded before and after LASIK.

Results:

at 6 months, the mean cylindrical component decreased in the group I from -6.53±1.64 D to -1.12±0.97 D, in the group II from -6.23±2.7 D to -2.36±1.68 D. Postoperatively the HOA root mean square (RMS) decreased from 3.88±1.15 μm to 2.65±0.18 μm after the wavefront-guided LASIK and increased from 3.65±0.11 μm to 4.31±0.23 μm after the standard LASIK (р<0.05). UDVA compared with preoperative values significantly increased in the group I from 0.04±0.12 to 0.71±0.22, in the group II from 0.05±0.08 to 0.41±0.25. The postoperatively UDVA was higher than the preoperatively CDVA in all cases after the wavefront-guided LASIK.

Conclusions:

The wavefront-guided LASIK is effective, safe and predictable procedure for treatment of induced refractive errors after the PKP.
