Abstract

Background: hyperopia, also known as far-sightedness, is a common type of refractive error in which light is focused behind, instead of on, the retina. This causes close objects to be blurry, while far objects may appear normal. Aim: this was evaluation study between different methods of preoperative refraction detection in hyperopic lasik including cycloplegic, manifest and wave front refraction for all patients and according to best-corrected visual acuity we do refractive surgery and analyze postoperative refraction outcome. Patients and Methods: the current study was carried out on thirty-four eyes of eighteen patients. All patients had primary hyperopia with or without hyperopic astigmatism. All patients were informed about the limitations and risks of the procedure. All patients signed an informed consent. Results: In hyperopic spherical group, the mean preoperative spherical equivalent regarding wavefront refraction was + 3.36 ± 1.26 (range + 1.70 to + 5.39 D). 6 months post operatively, it became + 0.35 ± 0.36 (rang + 0.12 to +0.90 D). In hyperopic astigmatic group, the mean preoperative spherical equivalent regarding wave-front refraction was + 3.13 ± 2.08 (range + 1.0 to +5.63D). 6 months post operatively, it became + 0.74 ± 0.43 (range + 0.12 to + 1.63D) and for Cycloplegic auto-refraction, it became + 0.92 ± 0.46 (range + 0.25 to + 1.74D). Conclusion: laser in situ keratomileusis for hyperopia, hyperopic astigmatism is a safe, effective and predictable technique. However, modification in the nomogram is needed in order to achieve good results.
