| Abstract | PURPOSE: To investigate the clinical significance of the internal lens signal measured using dual Scheimpflug anterior segment analyzer (Galilei(TM), Ziemer, Switzerland) in patients receiving cataract surgery. METHODS: The present study included 151 eyes of 148 patients who received surgery for senile cataracts from February 2012 to January 2013. Preoperative internal lens signals were measured preoperatively. The depth of anterior chamber and anterior angles were measured using dual Scheimpflug anterior segment analyzer preoperatively and 1 month postoperatively. Preoperative and postoperative best-corrected visual acuities (BCVAs) were measured. The relationships between preoperative internal lens signal and the changes in BCVA or anterior angles were evaluated. RESULTS: Internal lens signal and preoperative BCVA (log MAR) or preoperative anterior chamber depth were highly correlated (r = 0.287, p = 0.001 and r = -0.271, p = 0.004, respectively). Anterior angles increased 1 month after surgery compared with the preoperative values (p < 0.001). The amount of change between preoperative and postoperative anterior angles correlated with preoperative anterior angles (p < 0.001). However, no statistically significant correlation was observed between internal lens signal and preoperative anterior angles or postoperative BCVA. Internal lens signal correlated with changes in postoperative anterior angles (p < 0.001). CONCLUSIONS: Internal lens signal correlated with preoperative visual acuity and may help evaluate the cataract severity quantitatively and objectively. Internal lens signal may aid in understanding the structure of anterior segments by predicting the lens volume. Knowing the effect of visual impairment due to cataracts and predicting visual improvement after cataract surgery is necessary. |

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.
