Abstract | Microsurgery involves the manipulation of delicate membranes and vessels with a required accuracy often on the order of tens of microns, a scale at or near the limit of human positional ability. In addition, forces imposed by the tissue on the surgical tool during these manipulations are exceedingly small. Manual tasks performed using visual feedback alone (i.e., without tactile sensation) have been shown to take longer and be less accurate than tasks performed utilizing both visual and tactile information. Here we validate the hypothesis that retinal surgery is primarily vision based by measuring the magnitude of forces generated during simulated retinal surgery in cadaveric porcine eyes and comparing the results with the magnitude of forces discernable by retinal surgeons. Our goal is to improve microsurgical performance by developing robotic augmentation devices capable of enhancing the surgeon's ability to both position surgical tools and sense the surgical environment. The results of this study are an important guideline for such systems currently under development. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
