Abstract

Purpose:To evaluate the angle morphology in immediate and early postoperative period after FS-LASIK & SMILE

Methods:Prospective interventional comparative study evaluated 40 eyes of 40 patients undergoing myopic SMILE(n=20) or FS-LASIK(n=20). Angle parameters(AOD500&750, TISA500 &750, ARA500&750, TIA500&750) were assessed immediately after surgery and on POD1 using SSOCT

Results:No change in angle parameters in either group immediately post surgery.On POD1 significant increase in AOD750(p=0.03,0.006), ARA750(p=0.02,0.03), TISA750(p=0.03,0.008) & TIA750(p=0.01) in both groups and significant increase in TIA500(p=0.003), AOD500(p<0.001), ARA500(p<0.01) & TISA500(p<0.01) in LASIK. Significant correlation between preoperative SE and change in AOD750(r=0.64,p=0.04), ARA750 (r=0.7,p=0.02),TISA750 (r=0.69,r=0.02) &TISA 500(r=0.64,p=0.04) in LASIK Conclusions: Angle parameters increased in early postoperative after SMILE and FS-LASIK; changes correlated well with preoperative SE in LASIK group
