Abstract Details


To evaluate the long term efficacy, stability and safety of hyperropic correction in patients who underwent laser refractive surgery in zone 6,5 or 7,0 mm.


European eye clinic Lexum, Ostrava, Czech Republic


This retrospective study comprised 58 eyes after laser in situ keratomileusis with preoperative hyperopia or hyperopic astigmatism up to 3dpt. All patientsunderwent standard preoperative examinations including cycloplegic refraction, wavefront analysis and Scheimpflug images. Surgeries were perfomed using MEL 80 excimer laser.LASIK flaps were created using LDV femtosecond laser. The follow-up was 12 months. Uncorrected distance visual acuity (UDVA ), keratometry and regression were evaluated.


There was a substantial improvement in uncorrected visual acuity in both groups. One years postoperatively, UDVA was 0,97 in group with 6,5 mm zone, and 0,96 in group with 7,0 mm zone. In group with 6,5 mm zone 97% of patients achieved UDVA of 20/25 or better. In group with 7,0 mm ablation zone 97% of eyes achieved UDVA of 20/25 or better. Manifest refractive spherical equivalent was within �Â�± 0,50 dpt in 97% of patients in zone 6,5 mm and 93% of patients in zone 7,0 mm.There were no signifficant differences between zone 6,5 mm and 7,0 mm


Laser in situ keratomileusis for low hyperopia and hyperopic astigmatism yields satisfactory visual outcomes. Our study showed similar outcomes in eyes with 6,5 mm and 7,0 mm ablation zone.
