Ocular drug delivery systems and nanotechnology

Drug delivery to certain eye tissues has long been a major challenge for ocular scientists. Some problems with the standard formulations of drug solutions given as topical drops led to the introduction of various carrier systems for ocular dispersion. A lot of work is being done on ocular research to create safe, novel, and patient-friendly methods of pharmaceutical administration. After being enclosed in nanoscale carrier systems or devices, drug molecules are administered using invasive, non-invasive, or minimally invasive techniques. In the years to come, drug delivery may be greatly enhanced by the creation of non-invasive sustained drug delivery devices and studies into the viability of topical application to deliver medications to the posterior region. The difficulties related to a number of anterior and posterior segment diseases may be significantly reduced by recent advancements in the administration of ocular medications.
