Abstract Details

Purpose:

To assess tear film stability, ocular surface disease index (OSDI) score, Schirmer test value, tear film breakup time (TBUT), and tear osmolarity in patients with high myopic anisometropic amblyopia after laser-assisted in situ keratomileusis (LASIK) surgery.

Setting:

Institutional.

Methods:

PATIENT POPULATION: Eighteen amblyopic patients with high myopic anisometropic amblyopia (study eye) scheduled for surgery and good visual function in the fellow (control eye). Patients were excluded who were receiving chronic topical therapy, such as glaucoma medications, or had a history of previous ocular surgery. INTERVENTION: Examinations were performed preoperatively and 1 and 3 months postoperatively. At each visit, complete anterior and posterior segment examinations were performed.

Results:

Tear osmolarity changed from 302 ± 5.9 mOsm/L preoperatively to 308.8 ± 5.8 mOsm/L (P < 0.0001) and 304.1 ± 9.4 mOsm/L (P = 0.40) after 1 and 3 months postoperatively, respectively. Schirmer test did not change significantly 3 months after LASIK (P = 0.560). TBUT decreased significantly after first month and did not return to its preoperative value after 3 months. Subjective complaints measured by OSDI score, improved after 3 months compared with the preoperative level

Conclusions:

Although dry eye tests (Schirmer, TBUT, and tear osmolarity) are abnormal 1month after LASIK, they returned to preoperative values after 3 months. We can conclude that post-LASIK dry eye is a transient complication which will last less than 3 months with regular use of topical lubricants.
