Abstract Details


To study the time course of interface healing and find its correlation with visual recovery after ReLEx SMILE.


Nethradhama Super Speciality Eye Hospital, Bangalore


78 eyes of 39 eligible patients with mean age of 25.7 yrs who underwent bilateral ReLEx SMILE procedure were evaluated. On postoperative day 1, 15 and 90, retro-illumination photographs were taken after dilatation. The granularity of interface as seen in these photographs was graded into 5 grades(gd) of severity – gd 0(clear), gd 1(mild), gd 2(moderate), gd 3(severe) and gd 4(very severe with bowmans folds). The grade of interface healing was then correlated with UDVA, contrast sensitivity and aberrations at every visit.


On day 1, 55.1 % eyes had gd 3 granularity, 44.9 % gd 2 ,while none of the eyes had grades 0, 1 or 4. At 3 months, majority of the eyes (97.3 %) had improved to gd 0 and 1. Correspondingly, the UDVA improved from mean LogMAR of -0.063 and -0.079 at day 1 to -0.085 at 3 months. HOA improved from 0.169µ at day 1 to 0.152 µ at 3 months. Contrast sensitivity scores were also seen to be improving through the complete follow up period and were comparable to preoperative scores at the last follow up. Mean MTF value at 3 month was comparable to the pre-op MTF values.


Interface healing may be positively correlated with visual acuity, contrast sensitivity and aberrations after ReLEx SMILE procedure. The interface takes approximately 3 months for healing, during which there is constant improvement in quality of vision.
