Pars plana approach can be used for surgical injection technique

Topical ocular medications are an integral part of the pre- and postsurgical therapeutic regimen for cataract and other anterior segment procedures. The use of these mostly multi-dose topical medications introduces issues such as patient compliance, cumulative added drug cost to the patient, preservative-related alterations to the ocular surface and secondary visual quality degradation.The introduction of the “dropless” approach to the surgical therapeutic regimen appears to be a welcome modality that negates many issues with drops. However, such a turn in the path of ocular drug delivery poses new challenges and has to meet the litmus test of therapeutic efficacy, safety and absence of any major drug-related complications. New therapeutic routes of drug delivery during cataract surgery include the anterior chamber, posterior chamber, pars plana region and vitreous. Such a route of drug administration has the added advantage of direct, timely treatment of potential pathogenic organisms that may contaminate the interior of the eye during cataract surgery.
