| Abstract | PURPOSE: To evaluate the efficacy of deep anterior lamellar keratoplasty (DALK) using the big-bubble technique to manage keratectasia after laser in situ keratomileusis (LASIK). SETTING: Ophthalmology Department and Ophthalmic Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran. METHODS: In this interventional case series, preoperative and postoperative data of patients who had post-LASIK ectasia and DALK using the Anwar big-bubble technique between April 2005 and May 2008 were compiled. Indications for keratoplasty were intolerance of rigid gas-permeable contact lenses or unacceptable corrected visual acuity. Preoperative and postoperative uncorrected (UDVA) and corrected (CDVA) distance visual acuities, spherical equivalent (SE) refractive error, mean keratometry, and keratometric astigmatism were compared. RESULTS: The study included 11 eyes of 10 patients (mean age 31.6 years +/- 7.4 [SD]). The mean follow-up was 20.2 +/- 6.5 months. The mean UDVA increased from 20/400 before DALK to 20/160 after DALK (P = .39) and the CDVA, from 20/160 to 20/40, respectively (P = .007). The increase in the mean SE refractive error was 1.94 diopters (D) (from -11.53 +/- 5.4 D to -13.47 +/- 10.5 D) (P = .34). The mean keratometry was 46.81 +/- 7.2 D preoperatively and 46.31 +/- 1.9 D postoperatively (P = .81) and the mean keratometric astigmatism, 4.75 +/- 2.6 D and 4.55 +/- 2.5 D, respectively (P = .81), showing little change in either parameter. CONCLUSION: Deep anterior lamellar keratoplasty using the big-bubble technique effectively restored corneal regularity and thus increased CDVA; however, a high refractive error should be expected postoperatively.

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.
