Evaluation of tear film following Intacs for myopia.
Journal of Refractive Surgery 2002 March
PURPOSE: To evaluate the effect of intrastromal corneal ring segments (Intacs, Keravision) placement on the tear film quality as a measure of dry eye status.
METHODS: Seventeen eyes of ten patients underwent Intacs placement for the correction of myopia with spherical equivalent refractions ranging from -1.75 to -3.25 D (mean, -2.43 +/- 0.56 D). Dry eye grade values were measured preoperatively and at 1 day, 1 week, and 1 month postoperatively using the Kowa-DR-1 interferometer.
RESULTS: Preoperatively, the 17 eyes had a mean dry eye grade of 2.18 +/- 0.39 (range, 2 to 3). One day postoperatively, the 14 eyes measured had a mean dry eye grade of 2.64 +/- 0.63 (range, 2 to 4; P = .03). At 1 week the 17 eyes had a mean dry eye grade of 2.41 +/- 0.71 (range, 2 to 4; P = .25) and at 1 month, 2.18 +/- 0.39 (range, 2 to 3; P = .75).
CONCLUSIONS: There was transient dry eye following Intacs placement, but the tear film quality was restored within 1 week of surgery.
