Abstract Details

Purpose:

To evaluate the efficacy of bandage soft contact lenses (BSCL) in pain relief after femtosecond laser-assisted LASIK (FS-LASIK).

Setting:

Sadalla Amin Ghanem, Eye Hospital, Joinville, Santa Catarina, Brazil

Methods:

This prospective interventional randomized single-blinded study included fifty-two patients with a mean age of 38 ± 12 years that underwent bilateral FS-LASIK with the Femto LDV Z8 (Ziemer, Switzerland). Patients had a BSCL placed on one eye at the end of the procedure. Pain was assessed postoperatively by the Wong-Baker FACES Pain Rating Scale (0 to 10) in each eye after 1, 2, 4 and 6 hours and 1 day after the procedure, when the BCL was removed.

Results:

Mean (±SD) patient-scored pain after 1 and 2 hours were 2.5 ± 2.9 and 2.8 ± 2.8 with BSCL and 4.0 ± 3.2 and 4.0 ± 3.0 without BSCL (both p =0.001; Wilcoxon test). After 4 hours scores were 1.9 ± 2.4 with BSCL and 2.4 ± 2.7 without BSCL (p =0.025). After 6 hours and in the next day, scores were 0.7 ± 1.2 and 0.2 ± 0.6 with BSCL and 0.9 ± 1.6 and 0.2 ± 0.6 without BSCL (all p >0.05). Statistical analysis showed significant inverse correlation between age and pain scores.

Conclusions:

The use of BSCL after Femto-LASIK can significantly reduce postoperative pain in the initial four hours after surgery. Younger patients had significantly greater pain despite the use of BSCL.
