Abstract | PURPOSE: To compare the effects of the 4-haptic angulated (FA) intraocular lens (IOL) with the 2-haptic non-angulated (TNA) IOL vis-a-vis post-operative refractive error following phacovitrectomy with gas tamponade. METHODS: A prospective study was conducted on 40 eyes of 40 patients who underwent phacovitrectomy with gas tamponade for repair of macular holes. During surgery, FA (n=20) or TNA (n=20) IOLs were implanted randomly. Post-operative prediction of mean numeric error (MNE) and mean absolute error (MAE), and anterior chamber depth (ACD) were evaluated 3 months post-operatively. Forty eyes undergoing phacoemulsification-only were used as controls. RESULTS: The MAE of the FA IOL group was significantly less than that of the TNA IOL group (0.41±0.94 versus 0.91±1.24 D, respectively) (p=0.040). The post-operative ACD of the FA IOL group (4.02±0.25 mm) was significantly greater than that of the TNA IOL group (3.54±0.31 mm) (p=0.031). There was less of a difference in ACDs between the phacovitrectomy and the phacoemulsification-only groups with FA IOLs (0.21±0.04 mm) than between those with TNA IOLs (0.51±0.06 mm) (p=0.010). CONCLUSIONS: Eyes undergoing phacovitrectomy with FA IOL implantation showed less myopic shift than did eyes with TNA IOL implantation. Anterior shift of the IOL in the FA IOL group was less than that of the TNA IOL group, as shown by ACD measurements. Thus, a myopic shift should be taken into account when calculating IOL power with TNA IOLs following phacovitrectomy with intraocular gas tamponade. |

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.
