Postoperative changes in tear break-up time (tBUT, second), dryness symptoms (Sx), Schirmer test I (ST-I, mm) and tear meniscus height (TMH, mm) over time according to incision shape with a superior (A) or temporal incision (B) in the non-dry eye group. tBUT were shorter and Sx were worse with grooved incision than single plane incision at postoperative day 1 in the superior incision sub-group (p=0.04). Sx were worse in the grooved incision subgroup at 1 day (p=0.00), 3 days (p=0.01), and 10 days (p=0.01) postoperative in the temporal incision sub-group.
