Visual and Refractive Results of Cataract Surgery by Phacoemulsification Method in Patients with Keratoconus

Purpose: To examine the visual and refractive results of cataract surgery by phacoemulsification method in patients with keratoconus. Methods: In this retrospective study, the files of patients with keratoconus, who underwent phacoemulsification between 2008 and 2017, were evaluated. The intraocular lens power calculation formula was SRK/T. Post-operative visual and refractive results were analyzed. Results: A total of 36 eyes of 24 patients with the mean age of 61.2±8.7 (range: 42-73) were included. The mean post-operative spherical equivalent of refractive error significantly reduced (p<0.001). The mean pre- and post-operative cylinders showed no statistical significant difference (P=0.096). The mean corrected distance visual acuity (CDVA) significantly improved (P<0.001). The mean pre-operative keratometry obtained from biometry or topography showed no statistical significant difference (P=0.506). Conclusion: Cataract surgery in patients with keratoconus and cataract, and intraocular lens power calculation, using SRK/T formula, have optimal results.
