Abstract Details


To study outcomes of manual cyclotorsion compensation in patients with clinically significant astigmatism undergoing ReLEx SMILE for myopic astigmatism.


Nethradhama Super Speciality Eye Hospital, Bangalore


Patients undergoing ReLEx SMILE with a minimum manifest cylinder of -0.75 D were included.Horizontal limbal marking was performed at 0-180 degrees in upright position. The patients eye was docked to the contact glass of the treatment pack followed by application of suction. At this point, the extent of cyclotorsion was determined using the reticule in the eye piece. Any cylotorsion was measured in degrees by noting the relative position of the limbal marks in relation to 0-180 degree axis of the reticule.The cone was rotated to align the marks on the eye to the 0- 180 axis of the reticule.


A total of 70 eyes from 38 patients with mean age of 27.9 years were included. Preoperatively, mean SE treated was -5.29 D with a mean cylinder of -1.45 D (range -0.75 to -4D). Mean intraop cyclotorsion noted was 5.1 (0-15) degrees. 50 eyes had low (< -1.5 D), while 20 eyes had high cylinder (>-1.5D). Mean follow up was at least 3months. At the end of 3 months, mean SE was -0.20 D and mean cylinder was -0.27D.83% eyes were within ±0.5D, while 100% eyes were within ±1 D of intended correction. There was a mean undercorrection of -0.12 D seen at the end of 3 months. No post-operative complications were seen and no eye had loss of CDVA.


Excellent outcomes were achieved in terms of efficacy of cylindrical correction with manual cyclotorsion compensation in ReLEx SMILE in both low and high cyl groups with good stability over a 3 month follow up.
