Abstract
Objective: The aim of this study was to compare the outcomes of two different capsulorhexis techniques in the cataract surgery under an anterior chamber maintainer without using viscoelastic material. Material and Methods: This study included two hundred and four eyes of 189 patients (99 male and 90 female). Cataract surgeries were done in 102 eyes, phacoemulsification in 94 eyes and lens aspiration in 8 eyes by mini-nuc. The capsulorhexis eyes were divided into vacuum (group 1; 108 eyes) group and needle group (group 2; 96 eyes). Results: A successful capsulorhexis was achieved in 102 eyes in Group 1 and in 89 eyes in Group 2 (p= 0.41). The mean sizes of capsulorhexis achieved in Group 1 and 2 were 5.87 ± 0.30 mm and 5.90 ± 0.27 mm, respectively. During capsulorhexis enhancement, 6 eyes in Group 1 and 7 eyes in Group 2 had peripheral extension (p= 0.25). Conclusion: There was no significant difference between vacuum and needle groups. Use of an anterior chamber maintainer without using viscoelastic material allowed capsulorhexis through a 1 mm incision in all cases. Phaco devices and the developments in intraocular lens technology give the opportunity to use the same incision for capsulorhexis, phacoemulsification and intraocular lens implantation. Both methods had low cost, were safe and easy to apply for capsulorhexis. Copyright © 2009 by Türkiye Klinikleri.
