To investigate the effects of diquafosol tetrasodium (DT) 3% on conjunctival impression cytologic findings in addition to clinical symptoms and signs after cataract surgery in patients with preexisting dry eye disease (DED).
Ninety-four eyes of 94 patients with DED who underwent uneventful cataract surgery were included. In total, 50 patients were treated with DT 3% (group A), while 44 patients were treated with sodium hyaluronate 0.1% (group B) postoperatively, along with topical antibiotics and steroids. Conjunctival impression cytology was performed at baseline and at 4 and 12 weeks after surgery. Visual acuity, ocular surface disease index (OSDI), tear film breakup time (TBUT), keratoepitheliopathy score, Schirmer’s test, and tear clearance rate were measured at baseline and at 1, 4, and 12 weeks, and corneal aberration was analyzed at baseline and at 4 and 12 weeks.
The grade of conjunctival squamous metaplasia was lower at 12 weeks, and goblet cell density was higher at 4 and 12 weeks in group A than in group B (P < 0.05). Compared with group B, group A showed significantly lower OSDI scores at 4 and 12 weeks, longer TBUT at 1, 4, and 12 weeks, lower keratoepitheliopathy scores at 1 and 12 weeks, and lower total root-mean-square score and spherical aberrations at 4 weeks after surgery (P < 0.05).
DT 3% eye drops application after cataract surgery was effective in improving conjunctival epithelial morphology and goblet cell density as well as clinical findings in patients with DED.
