Abstract

Objective. We aimed to
investigate the influences of Nd:YAG (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 (BCVA), and intraocular pressure (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 (AL),
central corneal thickness (CCT), anterior chamber depth (ACD), and pupil diameter
(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 (p=0.345). No
association was found between the capsulotomy and mean IOP changes during the
follow-up period (p=0.300). No
significant changes were found in the CCT (p=0.059).
The ACD changes occurred at preoperative; the first week and the first month
were statistically significant (p<0.001).
No statistically significant differences were found between the first month and
the third month (p=0.365). No
significant changes in the pupil size (p=0.200)
and AL (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.
