PURPOSE: To evaluate the changes in functional visual acuity before and after neodymium:YAG (Nd:YAG) laser capsulotomy.
SETTING: Keio University Hospital, Tokyo, Japan.
DESIGN: Case series.
METHODS: Eyes that had previous cataract surgery with a clinical diagnosis of central posterior capsule opacity requiring Nd:YAG laser capsulotomy were evaluated. All patients had refractive error and corrected distance visual acuity (CDVA) measurements; slitlamp microscopy examinations, including posterior capsule opacification evaluation; high-contrast visual acuity measured at 5 m using a Landolt chart; 10% low-contrast visual acuity (LCVA); functional visual acuity; wavefront examination; and a Schirmer test without anesthesia.
RESULTS: The study enrolled 9 patients (4 women, 5 men; 10 eyes) with a mean age of 57.3 years ± 7.0 (SD) (range 47 to 68 years). Although there was no significant difference in CDVA before and after Nd:YAG capsulotomy, there was a significant improvement in the mean functional visual acuity, from 0.18 ± 0.11 logMAR (range -0.03 to 0.31 logMAR) to 0.08 ± 0.07 logMAR (range -0.04 to 0.18 logMAR) (P < .05). The LCVA improved significantly after Nd:YAG laser capsulotomy (P = .003). Higher-order aberrations and the root mean square of the 4th-order coefficients decreased significantly after capsulotomy, and these aberrations were significantly correlated with functional visual acuity and LCVA.
CONCLUSION: Results indicate that measurement of functional visual acuity is useful in assessing the quality of vision in patients who have Nd:YAG laser capsulotomy after cataract surgery.
