Abstract Details


Analysis of functional lacrimal complex (FLC) changes in patients after LASIK.


Ufa Eye Research Institute, Academy of Sciences of Bashkortostan


92 patients (184 eyes) with ametropia after LASIK underwent the study. Evaluation of CSF changes was carried out in terms of 1, 7 days, 1, 3 and 6 months after surgery. Diagnostic tests included: assessment of the corneal epithelium (vital staining of 0.2% fluorescein), Schirmer test-1 (without anesthesia), Schirmer 2 test, tear film break time (Norn test). In postop period patients were divided into 2 groups. The first group - 83 patients (90.2%) who had no overt signs of dry eye syndrome (DES). The second group - 9 patients (9.8%), who had severe DES.


I1st group patients Schirmer-1 test was 23,1 ± 1,4 mm,Norn test was 10,2 ± 0,8 sec. Staining of the epithelium in the central optical and paraoptical zone of the cornea revealed 3,2 ± 0,6 points. Restoration of normal CSF parameters - increase of basal and reflex tear production was by the 6-month (1,2 ± 0,3 points). In 2nd group Schirmer test-1 was 26,2 ± 1,1 mm,Norn test was 7,25 ± 0,7 sec. Staining of the epithelium in 2nd group was evaluated at 5,12 ± 0,75 points. Gradual recovery rates of FLC was observed during 6 months, without reach the norm values, indicating the continuing syndrome of 'dry eye'.


In patients after LASIK in most cases (90.2%) during the postoperative period is characterized by a border or a slight change of FLC indicators and the achievement of values normally occurs within 3 to 6 months period. Almost 10% of cases the changes of FLC in the postop period are persistent, causing dry eye syndrome.
