Purpose
To investigate safety and efficacy of Femtolaser-assisted LASIK with different laser ablation patterns to correct medium to high hyperopic defect.
Setting
Multicenter clinical practice: 1. Cornea and Refractive Surgery Unit - A. Gemelli University Polyclinic Foundation, Rome, Italy; 2. Primavista Eye Clinic, Rome, Italy
Methods
178 eyes of 104 patients with medium to high hyperopic defect. Group A1: 89 eyes (mean spherical equivalent (MRSE) of +2.99 Dioptres (D) ± 1.24 SD, range +0.75/+5.25 D) submitted to 60 kHz FemtoLASIK with Technolas 217C; Group A2: 43 eyes (MRSE of +3.18D ± 1,21 SD, range +1.25/+5.75 D) was submitted to 60 kHz FemtoLASIK with Teneo 317; Group B1: 21 eyes (MRSE of +3.43D ± 0.98 SD, range +1,25/+6 D) underwent 150 kHz FemtoLASIK with VISX S4; Group B2: 25 eyes (MRSE of +2.71D ± 1.42 SD, range +0.50/+5.25 D) was submitted to 150 kHz FemtoLASIK with VISX S4 customized wavefront laser ablation. Mainmeasures: uncorrected visual acuity (UCVA) and best-spectacle corrected visual acuity (BSCVA).
Results
One year postoperatively, UCVA was 0.96 ± 0.07 SD and BSCVA was 0.98 ± 0.05 SD in Group A1; UCVA was 0.95 ± 0.21 SD and BSCVA was 0.98 ± 0.15 SD in Group A2; in Group B1, UCVA was 0.98 ± 0.04 SD and BSCVA was 0.99 ± 0.06 SD; in Group B2, UCVA was 0.90 ± 0.17 SD and BSCVA was 0.93 ± 0.14 SD. Stability of refraction obtained from three months postoperatively.
Conclusions
Femtolaser assisted LASIK resulted safe and effective to correct medium to high hyperopia. 150 kHz femtolaser unit allows to reduce the amount of energy employed and the related surgical time. Customized wavefront treatments may be useful in case of larger pupil diameter.
