To present Optical Coherence Tomography (OCT) results in the evaluation of the vitreoretinal interface and macular statuses in patients undergoing laser–assisted in situ keratomileusis (LASIK).
26 healthy eyes in14 patients (4 males, 10 females) with a mean age of 34 years old (r=23–66 years old) undergoing LASIK for myopia, hyperopia or astigmatism, and without posterior vitreous detachment (PVD) were prospectively evaluated 1 day before and 1 day, one week and one month after surgery by means of fundus biomicroscopy, binocular indirect ophthalmoscopy and OCT. Mean spherical equivalent was –1.25 (r= +5.00 to –5.25), and axial length 23.50 mm (r=21.41 to 26 mm). With the Stratus 3.0 OCT (Carl Zeiss Meditec, USA), analysis of the macular morphology and thickness, and the vitreomacular and vitreopapillary interfaces was performed from six radial 6 mm scans centered on the fovea and on the optic disc by the same examiner.
None of the eyes developed a clinical PVD. Tomographically, neither separation of the vitreous cortex nor vitreoretinal abnormalities at the level of the vitreomacular and vitreopapillary interfaces was observed. Macular morphology and thickness remained unchanged in all eyes during the follow–up period (mean central thickness= 170 microns one day before, 166 one day, 171.5 one week, 171.5 one month after LASIK).
LASIK did not induce immediate PVD, macular edema or hemorrhage in low or moderate myopic, hyperopic or astigmatic eyes in this series.
