| Abstract | PURPOSE: To determine the homeostatic response of postoperative intraocular pressure (IOP) by analyzing postoperative IOP trends after sutureless phacoemulsification. SETTING: Asan Medical Center, Seoul, South Korea. DESIGN: Comparative case series. METHODS: Normotensive eyes were treated with sutureless phacoemulsification with in-the-bag posterior chamber IOL (PC IOL) implantation. The patients were randomly divided into 3 groups according to the intended immediate postoperative IOP as follows: Group 1, IOP less than 10 mm Hg; Group 2, IOP 10 to 21 mm Hg; Group 3, IOP over 21 mm Hg. The surgeon intentionally attempted supranormal, normal, or subnormal pressurization. The IOP was measured immediately after surgery and 2 hours, 4 hours, 1 day, 1 week, and 1 month postoperatively. RESULTS: Group 1 included 88 eyes (27.8%), Group 2 included 130 eyes (41.2%), and Group 3 included 98 eyes (31.0%). The mean IOP immediately after surgery was 6.4 mm Hg ± 2.0 (SD), 14.5 ± 3.2 mm Hg, and 27.0 ± 4.6 mm Hg, respectively, with significant differences between the 3 groups (P<.05). However, the IOP values were nearly normalized in the 3 groups 2 to 4 hours postoperatively. Twenty-eight eyes (8.9%) had an IOP lower than 5 mm Hg immediately after surgery in the absence of incision leakage. There were no postoperative complications related to hypotony. Thirty-one eyes (9.8%) had an IOP of at least 30 mm Hg immediately after surgery; the IOP normalized by 1 day postoperatively. CONCLUSION: In normal eyes that had uneventful sutureless phacoemulsification with in-the-bag PC IOL implantation, immediate postoperative high or low IOP did not affect the return to baseline levels. |

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.
