Abstract Details


To analyze visual outcomes and potential complications in patients who had PRK for myopia without adjustment of nomogram, and with a minimal follow-up of one-year


In-Patient and Out-Patient Departments of Aravind Eye Hospital, Coimbatore, India


Retrospective review of charts of patients who had PRK with a minimum follow-up of one-year. All patients had the procedure carried out by the same surgeon. Ninety-four eyes of 47 patients were included in the analysis. 63 eyes had compound myopic astigmatism. 29 had myopia only, and 2 eyes had only astigmatism. Spherical correction ranged from -1.00 Dioptres (D) to -6.75D, while astigmatism ranged from -0.50 to -3.00D. The highest spherical equivalent was -7.65D. All patients underwent wavefront ablation with the Bausch and Lomb Technolas217 Z100. All patients also had alcohol epithelialectomy and the application of mitomycin-C 0.02% x 2mins


Visual outcome was analyzed at the end of one year. All patients achieved 6/6 Visual Acuity, except for 5 patients (6 eyes): 4 achieved 6/6 partial in one eye, while 1 had 6/6 partial in both eyes. No complications such as delayed epithelial healing, mitomycin-C related melt, haze, or regression was noted


PRK without adjustment of the nomogram provides satisfactory visual outcomes in mild-to-moderate myopia and astigmatism
