Abstract Details

Purpose:

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

Setting:

Vissum and Miguel Hernández University, Alicante, Spain

Methods:

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.

Results:

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).

Conclusions:

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.
