Abstract Details

Purpose:

To determine possible differences in dry eye syndrome in relation to surgery methods, especially between small incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK), in Korean patients.

Setting:

Saevit Eye Hospital, Goyang, Korea

Methods:

This study involved 20 patients (20 eyes) who were treated with SMILE surgery and 23 patients (23 eyes) who were treated with FS-LASIK. The Schirmer test, tear film breakup time (TBUT), corneal staining score (CSS), and measurement of changes in the lipid layer thicknesses (LLTs) at 1 week, and 1 and 3 months after surgery were performed. Possible correlations between indicators of dry eye syndrome were then analyzed.

Results:

The TBUT was 5.52±1.50s after 1 week for SMILE patients and 4.59±2.50s for FS-LASIK patients (p = 0.02). The CSS was 0.50±0.51 after 1 week for SMILE patients and 1.14±0.99 after 1 week for FS-LASIK patients (p = 0.04). The CSS was 0.50±0.51 after 1 month for SMILE patients and 1.10±0.93 after 1 month for FS-LASIK patients (p = 0.03). 3 months later, the CSS was 0.39±0.50 for SMILE patients and 0.94±0.85 for FS-LASIK patients (p = 0.03). However, the Schirmer test and LLTs did not show a significant difference postoperatively for SMILE and FS-LASIK patients.

Conclusions:

When compared with FS-LASIK surgery, SMILE surgery resulted in significantly improved test results in the TBUT and CSS for dry eye syndrome.
