Abstract :Objective. We aimed to investigate the influences of Nd:YAG insert ignore into journalissuearticles values( neodymium-doped yttrium aluminum garnet ); laser capsulotomy on ocular biometric parameters. Methods. In this prospective study, 117 eyes of 117 pseudophakic patients were included. Full ocular examination, the best-corrected visual acuity insert ignore into journalissuearticles values(BCVA);, and intraocular pressure insert ignore into journalissuearticles values(IOP); measurements were performed before the procedure as well as one week, one month, and three months after Nd:YAG laser capsulotomy. The axial length insert ignore into journalissuearticles values(AL);, central corneal thickness insert ignore into journalissuearticles values(CCT);, anterior chamber depth insert ignore into journalissuearticles values(ACD);, and pupil diameter insert ignore into journalissuearticles values(PD); were measured by LenStar 900 optical biometry. The measurements were repeated one week, one month, and three months. Results. The BCVA improvements at preoperative, one week, and one month were statistically significant, but no significant changes in the BCVA were found at one month and three months insert ignore into journalissuearticles values( p =0.345);. No association was found between the capsulotomy and mean IOP changes during the follow-up period insert ignore into journalissuearticles values( p =0.300);. No significant changes were found in the CCT insert ignore into journalissuearticles values( p =0.059);. The ACD changes occurred at preoperative; the first week and the first month were statistically significant insert ignore into journalissuearticles values( p <0.001);. No statistically significant differences were found between the first month and the third month insert ignore into journalissuearticles values( p =0.365);. No significant changes in the pupil size insert ignore into journalissuearticles values( p =0.200); and AL insert ignore into journalissuearticles values( p =0.112); were found after Nd:YAG laser capsulotomy. Conclusıons. Our study demonstrated that the BCVA parameter changed after Nd:YAG laser capsulotomy. The BCVA and ACD values follow-up period should be at least one month after Nd:YAG capsulotomy.
