Amar Agarwal is the pioneer of Phakonit which is Phako with a Needle Incision Technology. This technique became popularized as Bimanual phaco, Microincision cataract surgery (MICS) or Microphaco. He is the first to remove cataracts through a 0.7 mm tip with the technique called Microphakonit. He has also discovered No anesthesia cataract surgery and FAVIT a new technique to remove dropped nuclei. The air pump which was a simple idea of using an aquarium fish pump to increase the fluid into the eye in bimanual phaco and co-axial phaco has helped prevent surge. This built the basis of various techniques of forced infusion for small incision cataract surgery. He has also discovered a new refractive error called Aberropia. He has also been the first to do a combined surgery of microphakonit (700-micron cataract surgery) with a 25-gauge vitrectomy in the same patient thus having the smallest incisions possible for cataract and vitrectomy. He is also the first surgeon to implant a new mirror telescopic IOL (LMI) for patients suffering from age related macular degeneration.
