Abstract Details

Purpose:

to compare the outcomes of the topography-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 34 eyes (34 patients) with residual ametropy after the PKP, out of which 16 eyes were operated by the topography-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, keratotopography and the anterior segment tomography were recorded before and after LASIK

Results:

after the keratorefractive surgery the mean cylindrical component decreased in the group I from 6.87±1.64 D to 0.82±0.97 D, in the group II from 6.23±2.7 D to 2.36±1.68 D. Postoperatively the surface regularity index (SRI) decreased from 1.34±0.22 to 0.72±0.11 after the topography-guided LASIK and from 1.25±0.37 to 1.08±0.15 after the standard LASIK (р<0.05). UDVA compared with preoperative values significantly increased in the group I from 0.04±0.02 to 0.51±0.22, in the group II from 0.05±0.08 to 0.31±0.25. The postoperatively UDVA was higher than the preoperatively CDVA in all cases after the topography-guided LASIK

Conclusions:

The topography-guided LASIK is more effective and predictable procedure compared with standard LASIK in the treatment of induced refractive errors after the PKP
