Methods: This is an observational, cross-sectional study. We studied 116 consecutive myopic eyes with −3 diopters (D) or more of astigmatism that underwent LASIK surgery. The magnitude of uncorrected residual refractive astigmatism 3 months postoperatively was measured. Results: The mean preoperative cylinder was −4.0±0.83 D (range, −7.5 to −3 D) and the mean preoperative ORA was 0.82±0.5 D. The mean residual refractive cylinder 3 months postoperatively was −0.78±0.83 D (range, −3 to 0 D). No correlation was found between ORA and the refractive cylinder 3 months postoperatively (P=0.6). Conclusion: In eyes with high myopic astigmatism undergoing LASIK, ORA was not correlated with the residual postoperative cylinder.engjournal articlehttp://doi.org/10.1038/eye.2014.133https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4135257/http://www.nature.com/eye/journal/v28/n8/full/eye2014133a.htmlrestricted access617.753.3617.753-089LASIKAstigmatismHigh Myopic astigmatismOcular Residual AstigmatismCirugíaOptometría3213 Cirugía2209.15 Optometría
