Topical anesthesia is a safe and cost-effective method considered as the first-choice in many procedures. The objective of the present study was to develop ocular inserts as a new form of lidocaine HCl to give a sufficient level of anesthetic. Ocuserts were prepared using HPMC and PVA in different ratios with lidocaine HCl alone and lidocaine HCl ${\beta}$-cyclodextrins complex. Drug polymer interactions were studied by Fourier transform infrared spectroscopic studies. The prepared ocular inserts were characterized by means of ocusert thickness, weight variation, folding endurance, surface pH, moisture absorption, drug content and in-vitro drug release. Stability study was conducted on selected formulations, and in vivo evaluation of lidocaine HCl was also carried out. The results revealed that F7 formulations containing drug ${\beta}$-cyclodextrins with 4 % HPMC and 2 % PVA were found to have good physical characteristics and appropriate flexibility. In addition to the highest initial and cumulative percentage of drug released in vitro. The selected F7 ocuserts retained their characteristics during the stability study. The results of in vivo study showed that the addition of ${\beta}$-cyclodextrins in F7 significantly increase the drug content in the aqueous humor when compared with F3 ocuserts containing lidocaine HCl alone.
