Laser in situ keratomileusis for hyperopia
Purpose:
To study the efficacy of laser in situ keratomileusis (LASIK) for hyperopia.
Methods:
We performed LASIK on 21 eyes using the Nidek EC-5000 excimer laser with software version 2.18 AH. The Chiron Automated Corneal Shaper was used to create the flap. Retreatments were needed in seven eyes due to decentration or undercorrection.
Results:
Although a high rate of satisfaction was noted among patients, complications were encountered such as decentration (three eyes), undercorrection (four eyes); one patient progressed to low myopia with a loss of spectacle-corrected visual acuity and one patient had regression 3 months after the initial LASIK.
Conclusion:
Although this technique has several advantages over other techniques (holmium, ALK, PRK, hexagonal RK), it has a high rate of retreatment and some complications. Software refinement is needed, and patients should be adequately informed about what to expect from this technique.
