Resumo: | The present study was aimed to evaluate the effects of topical 1% nalbuphine on corneal sensitivity and re-epithelialization, after lamellar keratectomy in rabbits. All protocols were approved by the Animal Care Comission of São Paulo State University (Protocol 028793-08) and were conducted in accordance with the Institutional Animal Committee and the Association for Research in Vision and Ophthalmology (ARVO) statement for the use of animals in research. Surgeries were performed on the left eye (Nalbuphine Group) and on the right eye (Control Group). Two groups were formed (n=10) and corneas received either 30µl of 1% nalbuphine (NG) or 30µl of 0,9% saline (CG). Treatments occurred at 7, 11, 15 and 19 hours. After the surgery, the corneas were stained with fluorescein and photographed daily; corneal touch threshold (CTT) was assessed with Cochet-Bonnet aesthesiometer, at 7 and 19 hours, 20 minutes after treatments. Data were statistically compared with repeated measures ANOVA and Bonferroni post-hoc test, and T test (P&lt;0.05). Average ±SD time for corneal re-epithelialization was 7.40±0.47 days (NG) and 8.90±0.31 days (CG) (P=0.11). The results showed that the diameter of the keratectomized area and CTT did not change significantly between both groups (P&amp;gt;0.05); however, a higher area under the curve for both parameters was observed in the NG (2771), in comparison to CG (2164). Topical 1% nalbuphine did not change significantly corneal sensitivity and re-epithelialization, after experimental lamellar keratectomy in rabbits.
