The Graphical Results of Myopia after Refractive Surgical Treatment by Femto2nd Optical Maser-Assisted and Epiboly’s LASEK (Eye-Surgery) have Remained Comparable.

Abstract

Background: In this prospective cohort study (flap-off epi-eye-surgery), the results of femtosecond optical maser-assisted in situ keratomileusis (femto-eye-surgery) and epipolis eye-surgery refractile surgery for myopia were compared. Purpose: Comparison of the results of eye-surgery myopia or myopic astigmia improvement by a six- multidimensional amaris exciter optical maser and establish that both femto- eye-surgery and flap-off epi-eye-surgery are safe, effective, and predictable in Amanat eye hospital Rawalpindi. The duration of the study was July 2019- July 2021. Sample size was 400 eyes, 200 patients, 81 male and 119 female. The study was conducted after the ethical approval of the hospital ethical committee. Methods: Four hundred (400) eyes from 200 individuals were divided into two groups in this prospective cohort study. For femto-eye-surgery flaps, a femtosecond optical maser was used, while an epikeratome (flap-off) was used for epi-eye-surgery flaps.  The researchers  measured uncorrected distance graphicalacuity (u.d.v.a), corrected distance graphical acuity (c.d.v.a), visible bending (m.r), corneal asphericity (q-value), and corneal higher-order aberrations (hoas) before and after surgery. In both groups, the improvement in logmar udva following refractile surgery was statistically significant (p< 0.001 for all); it was significantly higher for femto-eye-surgery 1 day and 1 week postoperatively (p <0.001 for femto-eye-surgery, respectively). Results: Logarithm of the minimum angle of resolution (logmar) of udva after refractile surgery was statistically significant for both groups (p = 0.002); it was significantly higher for femto-eye-surgery than flap-off epi-eye-surgery (0.03 *0.06 logmar (femto-eye-surgery) and 0.54 * 0.31 logmar (flap-off epi-eye-surgery ) at 1 day postoperatively; 0.02 *0.05 logmar (f the increase in spherical aberration (z4,0) in flap-off epi-eye-surgery was reater than femto-eye- surgery : 0.626 ± 0.232 μm and 0.479 ± 0.139 μm in the front cornea; 0.556 ± 0.227 μm and 0.430 ± 0.137 μm in the total cornea (p = 0.016 and p = 0.017). There was no significant impact of the changes to the corneal hoa in the back of the eye on the corneal hoa in general. Conclusion: Despite the fact that femto-eye-surgery generated better early graphics results than flap-off epi-eye-surgery, there  was no significant difference in the results one week following surgery.
