Abstract Details

Purpose:

To evaluate and compare visual and refractive outcomes after primary LASIK surgery for the correction of low and moderate myopia using customized and standard treatment protocols

Setting:

S. Fyodorov Eye Microsurgery Federal State Institution, Moscow, Russia

Methods:

We observed 748 eyes with low and moderate myopia, out of which 258 eyes were operated by the Wavefront-guided algorithm (WFG), 243 eyes – Topo-guided algorithm (TG), 247 eyes – standard ablation (control). All flaps were formed with the femtosecond laser and all eyes were treated by the MicroScanVisum excimer laser (Russia). The customized ablations were calculated with PlatoScan and KeraScan-M softwares

Results:

The percentages of eyes achieving a postoperative UDVA of 20/20 and 20/16 were 94,2% and 69%, 93% and 47%, 88,3% and 34,8% in the WFG, TG and control groups, respectively. Postoperative SE was within ±0.5 D in 95,7%, 94,2% and 89,5%, respectively

Conclusions:

All evaluated LASIK treatment protocols are predictable and effective for the myopia correction. The treatment planned with aberrometer and keratotopography data obtained the best postoperative refractive outcomes
