%X <strong>Purpose:</strong> To evaluate axial length before and after the photorefractive keratectomy (PRK) and laser <em>in situ</em> keratomileusis (LASIK). <strong>Setting:</strong> Alhokama Eye Center, Riyadh Saudi Arabia. <strong>Design:</strong> A cross-sectional study. <strong>Methods:</strong> The study sample was comprised of 106 eyes of 54 patients. Patients were divided into 2 groups based on whether they had photorefractive surgery (PRK group) or laser <em>in situ</em> keratomiluesis (LASIK group). The intra-group comparison was performed of the changes in axial length before and after surgery using IOLMaster. <em>P</em> &lt; 0.05 was considered statistically significant. <strong>Results:</strong> There were 76 eyes (39 patients) in the PRK group with the mean age of 25.10 ¡À 3.47 years, the mean preoperative spherical equivalent of -3.16 ¡À 1.75 D, and the mean preoperative axial length of 24.79 ¡À 1.02 mm. In the LASIK group, there were 30 eyes (15 patients) with the mean age of 25.13 ¡À 4.91 years and the mean preoperative spherical equivalent of -5.58 ¡À 1.98 D and the mean preoperative axial length of 25.67 ¡À 1.35 mm. Postoperatively, the mean axial length was 24.70 ¡À 1.14 mm in the PRK group and 25.60 ¡À 1.33 mm in the LASIK group. The mean change between the preoperative and postoperative axial length was statically significant in both groups (<em>P</em> &lt; 0.00001, both intra-group comparisons). <strong>Conclusion:</strong> There was a statically significant decrease in the axial length measurements after PRK or LASIK for myopia.
