Background: Compare the residual refractive power following “small incision lenticule extraction” (SMILE) surgical correction in myopic patients with moderate to severe myopia and
myopic astigmatism.
Aim: To study the pre op with post op residual refractive status comparison in low to high myopia and myopic astigmatism patients under gone ReLEx SMILE operation.
Methods: Prospective comparative analysis with 65 eyes of 33 patients classified into three groups19: mild myopia -1.00 to -3.00 D, moderate myopia -3.25 to -6.00 D, and high myopia -6.25 to -10.00 D, comprising spherical and cylindrical using spherical equivalent (SE). Using the SMILE surgery, each patient were corrected for myopic refractive error. Retinoscope was conducted preoperatively and postoperatively one day and one month following surgery, respectively. Results: Pre op 1 day and 1 month are showing a significant and gradual decrease where low and high myopia are compared, which is statistically significant for both one day (0.007) and one month (0.001) post operatively, but low to moderate (0.282) and moderate to high (0.147) post operatively 1 day and 1 month it is not statistically significant. This indicates that high myopia has greater residual power than low and moderate myopia.
Conclusion: This research concludes that residual power increases as myopia increases in severity. As the objective residual power after SMILE surgery is less than +/- 0.50D in approximately
75% – 80% of eyes, SMILE surgery is a suitable alternative for refractive surgery correction with less complications than other refractive surgery techniques.
