With continuous scientific research and technology breakthrough particular in the medical field, new inventions are constantly introduced into eye cataract surgery. One of the latest and could be considered as the significant development in cataract surgery is the use of topical anesthesia and the introductions of Multifocal IOLs and Toric IOLs.
Topical anesthesia is very helpful as it eliminates the need to bear painful injection by the patient. In the past, surgery was done by getting an injection directly into the eye, which of course caused a lot of pain and risk. With topical anesthesia, the whole operation which usually lasts for around 15 minutes is performed without the need of an injection but instead using only eye drops. The great benefit of topical anesthesia is that the patient does not need to bear the risk and pain which involved in normal surgical procedure. Moreover, the results from using this technique are much faster and satisfying. The patient can even go home after resting for some times at the hospital and without a patch.
