Background: currently, LASIK is one of the most common surgical procedures for refractive disorders, including hyperopic defects. Objective: to assess the results of laser-assisted in situ keratomileusis for the treatment of hyperopic defects. Methods: an ambispective study was conducted in 31 eyes (16 patients) operated on for hyperopia and simple and compound hyperopic astigmatism in the Refractive Surgery Unit of the Ophthalmology Department of the Hermanos Ameijeiras Hospital between January 2009 and December 2010. Visual acuity with and without optical correction, spherical and astigmatic component before and after surgery and intra- and postoperative complications were analyzed. Results: patients aged 40 to 49 years predominated; compound hyperopic astigmatism was the most frequent defect; the mean uncorrected visual acuity improved and remained stable up to six months after surgery; the average values were 0.87 for moderate defects and 0.79 for high defects with optical correction. The mean sphero-cylindrical component decreased. The efficacy and safety rates were acceptable for moderate and high degrees of the defects and predictability was 100 % for all degrees of ametropia. Conclusion: LASIK is a safe, effective and predictable procedure to treat patients with moderate and high degrees hyperopia and hyperopic astigmatism.
