The 70 eyes were divided equally into two groups. Group A (\n n<\/jats:italic>\n = 35) and Group B (\n n<\/jats:italic>\n = 35) underwent DSEK and DSAEK procedures, respectively. the operating surgeons prepared the manually dissected corneal grafts using lamellar dissectors. the eye bank technicians prepared the precut corneal grafts using a microkeratome. The patients were investigated postoperatively after 1 day, 1 week, 1 month, 3 months, and 6 months. The data were compared for visual outcomes [uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), spherical and cylindrical refraction, and spherical equivalent], incidence of postoperative complications, and pachymetry.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n The mean age was 56.5 (\u00b117.8) years, and the male-to-female ratio was 1.3:1. The most common indications were pseudophakic bullous keratopathy (45.71%, 32\/70), failed graft (32.86%, 23\/70), and Fuchs\u2019 endothelial corneal dystrophy (10%, 7\/70). The indications for surgery (\n P<\/jats:italic>\n = 0.732) and donor (\n P<\/jats:italic>\n = 0.258) and host pachymetry (\n P<\/jats:italic>\n = 0.986) were comparable between both groups. There was no significant difference in change of UCVA, BCVA, and postoperative refraction (mean spherical refraction,\n P<\/jats:italic>\n = 0.849; mean cylindrical refraction,\n P<\/jats:italic>\n = 0.516; spherical equivalent,\n P<\/jats:italic>\n = 0.518) between the two groups. Postoperative complications like graft detachment (\n P<\/jats:italic>\n = 0.179), graft failure (\n P<\/jats:italic>\n = 0.513), graft infiltrate (\n P<\/jats:italic>\n = 0.428), and endophthalmitis (\n P<\/jats:italic>\n = 0.493) were higher in the DSAEK group; however, the difference between the groups was insignificant. The graft asymmetry index was higher in DSAEK than in DSEK; the difference was significant till the 1-month follow-up (\n P<\/jats:italic>\n = 0.005).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The outcome was similar in both groups. Therefore, manual donor dissection can be an alternative for microkeratome-assisted dissection in low-resource centers and countries to achieve good results.<\/jats:p>\n <\/jats:sec>","DOI":"10.4103\/ijo.ijo_3282_23","type":"journal-article","created":{"date-parts":[[2024,7,11]],"date-time":"2024-07-11T12:09:08Z","timestamp":1720699748000},"page":"1728-1733","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Microkeratome versus manually dissected donor tissue for Descemet stripping endothelial keratoplasty: A randomized prospective study"],"prefix":"10.4103","volume":"72","author":[{"given":"Ritu","family":"Mali","sequence":"first","affiliation":[{"name":"Cornea and Anterior Segment Service, L.
