Purpose
To assess the clinical results of hyperopia (H) and hyperopic astigmatism (HA) Femto-second Lasik (FS-Lasik) correction.
Setting
Tertiary-care eye-center.
Methods
Retrospective study of all 188 consecutive eyes (110 patients, median age 39 years) treated using Visumax 500 (Carl Zeiss Meditec) for flap creation and Technolas Teneo-317 model II (Bausch+Lomb). Eyes were divided into 2 sub-groups according to preoperative spherical error (SE), (Group1 <3 Diopters(D), Group2 ≥3D). Safety index (SI, postoperative CDVA / preoperative CDVA) and efficacy index (EI, postoperative UDVA / preoperative CDVA) were compared within subgroups.
Results
After a mean follow-up of 3.53 ±1.19 months,145 eyes (92%) reached UDVA of 20/25 or better, and 129 eyes (73 %) reached 20/20. 6 eyes (3.2%) lost 2 or more lines of CDVA.18 eyes (9.6 %) gained one line and 2 eyes (1.1 %) gained two lines.149 eyes (79%) were within +/-0.50 D and 180 eyes (95.74%) were within +/-1.00D from target refraction.SI was 0.98±0.23 and EI was 0.90±0.27. In group1 both SI and EI were higher (p=0.001 and 0.002) than in Group2. In the 157 eyes with plano target, compared to preoperative, at last visit postoperatively there were significant differences in mean SE(p<0.001), in mean cylindrical eror( p<0.01) in mean K1(p<0.01), in mean K2 (p<0.01) and in mean Kmax (p<0.01). There was no difference in mean CDVA (p=0.396).
Conclusions
FS-Lasik correction appeared to be effective and safe when correcting H and HA erors. SI and EI were better in patients with SE lower than 3D than in those with 3D and more.
