| Abstract | Objective To analyze the characteristics of anterior segment biometric parameters in moderate, high, and super-high myopia eyes for ICL size selection. Methods A total of 246 eyes of 131 patients were included in this prospective observational cohort study. Preoperative axis length (AL), central keratometry (Kc), central corneal thickness (CCT), white-to-white (WTW), internal anterior chamber depth (ACD), trabecular iris angle (TIA), anterior chamber width (ACW), angle-to-angle distance (ATA), crystalline lens rise (CLR), lens thickness (LT), sulcus-to-sulcus (STS), ICL size, and postoperative vault at 1 month were recorded and compared among the different degrees of myopia groups. Results The moderate myopia showed smaller ACD and TIA than high and super-high myopia (P < 0.05). A higher proportion of CLR positive (+) was in the moderate myopia group (65%), while the super-high myopia group had a higher proportion of CLR negative (-) (55.3%). (P = 0.047). There were no statistical differences among the myopia groups in WTW, ATA, ACW, STS, LT, and postoperative vault (P>0.05). In different degrees of myopia groups, vertical ATA, ACW and STS were longer than horizontal ATA, ACW and STS (P < 0.001), and horizontal-STS showed a higher correlation with horizontal-ATA (r = 0.655) and horizontal-ACW (r = 0.660) than with WTW (r = 0.591). The 12.1 mm size ICL was slightly selected in moderate myopia (35.8%) more than high myopia (14.6%) and super-high myopia (26.3%) (P = 0.013). Conclusion Compared to high and super-high myopia, moderate myopic eyes exhibited smaller ACD, TIA while similar WTW, ATA, ACW and STS, with the lens positioned more anteriorly. It should be concerned to the effect of sagittal axis parameters ACD and CLR on the ICL size in different degrees of myopia. |

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.
