Abstract Details


To evaluate the corneal ablation stability of the achieved correction of hyperopia in the long-term with the sixth generation excimer laser.


Vissum and Miguel Hernández University, Alicante, Spain


This retrospective consecutive observational case series study comprised 66 eyes of 38 patients who underwent Laser in situ keratomileusis (LASIK) to correct hyperopia with a postoperative follow-up of 3 years. LASIK procedures were performed using the 6th-generation Amaris excimer laser. Visual outcomes, stability of corneal topography and aberrometry were evaluated in the follow-up.


Statistical significant differences were found in the SE between 3-36 months (p<0.01), but no statistical differences were observed between 12-36 months (p=0.06). A statistical significant difference was observed in the mean simulated keratometry between 3-36 months after surgery (p=0.04), but no statistical difference was observed between 12-36 months (p=0.17). The horizontal and vertical optical zone diameters were 4.45±0.47 and 4.87±0.44mm 3 months postoperatively and 4.56±0.42 and 4.91±0.41mm 3 years postoperatively, respectively, with no statistical significant differences along the follow-up (p≥0.06). No statistical significant difference was detected in RMS higher-order aberrations along the postoperative of follow-up (p≥0.08).


Treatment of hyperopia using sixth-generation Amaris excimer laser provides very good results in terms of topography stability and visual outcomes after 3 years. The topography and refractive stability shows more stable results from 12 months postoperatively.
