One of the latest and the significant development in cataract surgery is topical anesthesia, and the development of multi-focal intraocular lenses. Topical anesthesia eliminates the need for painful injection and the patient can go home in few minutes without a patch.
Cataract surgery has been performed for many years. Recent technical innovations have contributed to the refinement of both cataract and refractive surgery, with the new development in intraocular lenses and the introduction of new software technology has helped a lot. Earlier cataract surgery involved simply removing the cloudy lens from the eye. As technology advanced anterior chamber intraocular lenses were developed. These artificial lenses were placed in front of iris to replace the removed lens. They worked well, but over the time the cornea was damaged in most of the patients due to vibration of lenses as a result of aqueous fluid from the back of the eye toward the front resulting in swollen cornea and cloudy vision.
The next big change in cataract surgery was the development of posterior chambers intraocular lenses. These were placed behind the iris, and thus eliminated the vibrations and thus preventing the cornea from further damage. Over the years improvements were made in lenses better quality, smaller and flexible lenses were developed so that they can be implanted with very small incision. The basic problems with all these lenses were that distant objects were visible but for seeing close minute objects and for reading one has to depend upon glasses. To overcome this problem, multi-focal intraocular lenses were developed. These lenses were designed to give the patients full range of vision from distant to near without wearing eyeglasses.
One of the latest and the most significant development in cataract surgery has been the use of topical anesthesia. In past cataract surgery was done by getting an injection in the eye which involved pain and risk. Now the entire surgery which lasts only for 15 minutes is done without an injection, using only eye drops. The advantage of topical Anesthesia is that you are spared from the risk and pain which is involved in normal operation apart from that the results are much faster and satisfying the patient can go home without a patch in just 15 minutes.
